• microphone frequency response function

  Hi all

  I am doing a test with 3 types of sensors to study the properties of the surface of a material.

  The first is the sensor in the modal hammer.

  The second sensor is a geophone, while the last is a sensor of air coupled in the form of a microphone.

  Apart from the microphone that is directly connected to the laptop by USB, the instrumented hammer and the geophone is connected to the NI 9233, which is connected to the NI USB-9162 that eventually connects to the laptop.

  Does not support this material analog trigger so software triggering is used.

  I use an example of http://www.ni.com/example/28438/en/ vi

  I installed successfully the LabVIEW VI to read the raw data from all the sensors and to obtain the frequency response of the geophone due to the momentum created by the hammer signal.

  I tried to get the frequency response of the microphone due to the modal hammer However no results appear in the graph for the frequency response of the microphone.

  My question is, what's going on and how can I fix this so that I can get the frequency response of the microphone?

  I enclose my vi for your review.

  I can't fix your VI because I don't have DAQmx or SVFA Toolbox. What I joined is a simulation that shows some of the concepts.

  The left side simulates the acquisition of two channels (hammer and geophone) via the DAQ hardware and a sound channel (microphone).  Don't worry too much about the details. I just threw together quickly. The hammer is a square pulse, the geophone signal is a cycle of a sine wave with the noise and the microphone signal is a cycle of a triangular wave more noise. Each pulse is delayed at the beginning of the acquisition by different amounts to represent delays of transmission of the audio and vibration.  The values are arbitrary and do not simulate any what physics.

  I used the sampling frequency, block size and controls the duration of your VI, so the number of samples and the sampling frequency should be the default values for your VI. The three graphs show left the three generated signals. Note that the Microphone graph x autoscaling off axis. Also, the data are all in waveforms or arrays. I avoid using the Type of dynamic data produced by screw Express because it effectively masks the data structure.

  The right side shows a way to make the trip. I used the basic Detection.vi of the control palette trigger level of waveform and get the Subset.vi of waveform in the waveform palette. Note that there is separate shutter screw for acquisition of data channels and the sound channel. Because they are not started at the same time and they do not have the same dt (= 1/sample rate), the waveforms are not cumulative to use a single trigger. The geophone signal is synchronized with the hammer for a trigger signal the hammer can be used to get the two subsets.

  Note that with the default times the pulse of the microphone occurs 30 ms after the geophone impulse but in subsets, it happens about 4 ms before the geophone. This is due to the independent intervention.

  Since you do not have a common signal or a trigger for both devices (acquisition of data and sounds), you may not know exactly what the relationship of synchronization between them. On each run, the differences between start times will vary. So, you will need to make some kind of calibration to determine the offset.  I think some sort of periodic stimulus that will produce several impulses for the geophone and the microphone. The first pulses aura of indeterminate delays but subsequent impulses should be reproducible delays. The relative spacing and directions during the calibration tests must be identical to the position of hammer for the real experience.

• Frequency response of a filter

  I have the coefficients of the filter from the filter that I need in my program. I need to find the frequency response of the filter. Is there any function in LabVIEW that helps me do that?

  I guess I need a function that is similar to the freqz function in matlab for this.

  Thank you guys!  I discovered what I wanted. But thanks to guide me.

  I'll post the answer so that others can use it

  First of all, I discovered the transfer (from the filter coefficients) of the filter function using the:

  Digital Filter Design toolkit-online Utilities => tf (DFD build transfer Function.vi filter)

  The output filter obtained this was wired as a the input filter for:

  Digital Filter Design toolkit-online filter analysis-online Freq resp (DFD Plot Freq Response.vi)

  I had the required frequency response .

  @Sd.Kfz.10 I could not use the filter filter RII where the coefficients are given as input (in the toolkit signal processing) and FIR because I wanted the only filter response. These FIR and IIR filters requires the table of input signal.

  I used for the linear predictive coding for speech recognition. I modeled the vocal tract as a model (a filter all-pole) Autoregressive using a the AR modelling.vi in the ADSP Toolbox. I wanted to see the frequency response of the filter modeled but I only had the filter coefficients.

• frequency response plot DFD rad / s

  Hello

  I'm trying to get the filter frequency response using the frequency plot vi DFD response. Is it possible that I can get the mangnitude and phase response of the plots of the frequency in radians per second? Now it gives me focus of frequency in Hz.

  Suni-

  The output of the frequency plot DFD response is an array of clusters of wave graphic form.  You will need to index the table out each graph (there is one in your example) and then bring out the start frequency and out of the frequency of the cluster so that you can convert to radians and insert and rear.  The attached picture shows what I mean...

• Flat frequency response

  I probably wouldn't ask this question because I charge people for my amateur obviously recording capabilities but it's one I've ever had explained to me and I need to know the answer to one...

  I would like to settle the matter in this way:

  When you get in the car and pop in a cd of product professionly, most of the people get the control treble for 6-10 (on a scale of 10) and bass (4-10) upwards according to the factory speakers and the type of material and whether or not they care what their music sounds like. When you get home and you listen much finer stereo home always to listen to professionally produced album, always reach you for these high and low buttons and crank them several notches or if you have a graphic equalizer twist you on a smiling face .

  There is so much importance in the world of recording to get out of your room with shock absorbers flat frequency response and bass intercepts and spread around the reflections with deflectors, etc etc... etc., we spend thousands of dollars on such things and some measurement software to make sure that it is flat. Then we use this flat response to produce music that sounds good and waiting for the translation of these cd players and home stereo systems.

  (I will additonally Preface my question by saying that I had no problems to make my music to translate my home studio to any other system of reading, but I'm a little confused as to what is happening.)

  Now finally my question (s), when we reach for these buttons high and low on our car and home reading systems, are we really just try to compensate for the lack of bass and top of the range in these systems so that we can get a flat frequency response and too make the music sound good on any system?     or

  Do we as listeners prefer the face smiley in music frequency response and are we take a cd that has a flat frequency response and make a smiley face out of it to make it sound to our ears? (Please don't give me an answer for material/gender.)

  The reason why I ask is because I have to put a graphic equalizer on my monitors 2031A truth to make professional stuff sound good thanks to them and then I Mix round my music for the same material/any sound of course. (I'm not really interested in any monitor bashers or I would already put this on to Gearslutz.)

  Even once be reformulated... The masses think that music sounds good when you have a flat frequency response or the smiling face and if the these States among young people, how are supposed to realize that when the facility from our home studio produces a flat frequency response, do give us our EQS instructors like me?

  Additonaly, I understand that when talking about frequency response flat in the rooms, that we are not talking about launch thanks to a system sine waves and the going of their frequencies, measure so them we can detect everything on the focus/deficiencies in the room then maybe this question is a little more to the tuning monitor.

  If you are looking for Fletcher and Munson in Google, you could start to do a little the beginning of any idea why this is not quite as simple as it seems... and I'm not sure I can give you a complete answer, although I peut give you a few things connected but somewhat randomly, to meditate wearing my acoustician Hat:

  The fundamental problem is that, when things are quieter (and less distorted, by the way) our ears get more sensitive to frequencies medium, and if we listen to music like that, it always sounds as if the bass and treble are unbalanced. In cars, it is slightly different though; the frequency response of everything that is there generally tends to be anything but flat - and often too emphasizes the middle range anyway. Treble tends to be absorbed very easily in padded cars, and because most car speakers got nothing as acceptable to the tweeters in order in General, it is not surprising that people want to increase the treble. As for the bass - well I am still lower that personally, but I know what you mean in principle!

  If by a "commercial" CD, you mean the one where the voice is important, so yes I can easily imagine why you could as naturally want to increase the response to the extreme - that makes sense, if you think about it. The mid-range voice is prominent and probably compressed, so its average level is stronger support - helps it stand out. But also it distorts the overall time response - support can be balanced so it's not serious in itself, but which does not always if you have the wrong applied voice settings, or at the very least, applied said. And some voices are much worse; for example Sealion dying (AKA Celine Dion) makes the most appalling racket in the middle range, and you should certainly less of it!

  So, really, I would say that it is not a question of bass/treble, but a mid-range one. If you look at commercial CD in general, you tend to find that the energy distribution is pretty even on the entire audio band, which means it comes off at 6 dB/octave, if you look in hearing (it is something energy/Hz), but in reality most of the CD these days are here mixed a little brighter than that - more like a - 3 dB/octave descendant of about 1 kHz , and it is partly to make up for a lot of things - some of which are cars... You have to watch out for the problem of good distortion - most people don't realize, but you are able to tolerate rather high undistorted sound anything with levels of serious distortion in it, and if this distortion is in the middle range, then you will like it more quiet even when. Then under-run decent, over-rated sound systems always sound more clean and strong but you should beware - they can damage your ears just as much, if not more.

  Car interiors they increase the chances of the mid-range boost that occur?  I think it's a pretty safe bet they do, in General, simply due to the size and the acute problem, I've already mentioned. And if you try to compensate for too much mid range, then the rest follows. More home replay systems these days seem to be heavy mid-range for me as well - I heard something cheap recently which was something as a flat - response and they really agrees that they are in both chambers.

  If you want to listen to material as it really should be, then you need to experience it live first, and then I would say do a direct comparison with what you hear in your monitors. I'm lucky - I can do fairly regularly with a variety of materials. I tend to leave things like dish, as they are saved? Well, it depends on what it is. If it is somehow classical, then sometimes I watch carefully the low balance, but generally, I leave the rest alone. The rest of our days I just get its good - and this can mean all sorts of settings, depending on all sorts of things. More and more, I came to the conclusion that medium too is not necessarily a good thing – but it's mainly because of the general lack of good material around these days.

  Regarding the monitors and flatness - well it is not really a problem for most people, compared with obtaining their correct listening environment. If you have a pair of cheap monitors in a good room, chances are the results will sound better than a cheap pair in a room uncorrected - despite what all fans of monitor on gearslutz might say. Nowadays, even the least expensive may seem quite respectable. But the flatness is not really a problem with the monitors - a decent impulse response and low distortion are much more important. Chances are that if a manufacturer got that right, the monitor will be properly 'revelation' anyway - which is what a monitor is supposed to do.

  The only thing you do not do however, is QE the stream of your monitors - that went out of fashion, as soon as he came in--fortunately. You can set the room so that it is the most truthful. If you EQ the battery monitor, it will inevitably be only its good in one place in the room, and it's no use to man nor beast. Things only decent that can do real room correction systems is to equalize the immediate response of time to account for what is actually between you and monitors which if done properly can improve an image without end stereo.

  If the answers? Well not really. But at least I explained a bit (but not all) of the questions.

• Pavilion dv6 slow and non-responsive

  Hello

  I have a pavilion referbished with Windows 7 about 6 months ago and for most of the time it worked great. However, one day he gave me an error message during start-up by saying he could not start and that he should try again. I have yet to get this error, but since then he acted weird. It starts normally and the first first seems normal, if there might be a little slow. However, after about 10 to 20 minutes of use, it will start to slow down the hydro-huileuses gel and effectivly upward. I can still control slider, but most of the programs are no longer.

  Three other things:

  (1) Norton will not open, even if I try as soon as the computer starts when everything else works fine

  2) unless I try immediately after start-up computor not restart or shut down. The icons will disappear, but it does not start to close. It also has problems going in the Task Manager after the first few minutes.

  (3) it works perfectly in safe (at least relitive in safe mode) mode.

  What I've done so far:

  I did a full scan of malwarebytes: he found nothing but during the scan, a message saying poped windows is maybe damaged.

  I called Norton:  I tried to figure out why it wouldn't boot up normally and it does not work in SafeMode (which is dumb). They had me run another program designed to run in safe mode, what did not and could not help me with another problem.

  I did a system restore- it did nothing

  I did a scan of the memory- he also found nothing

  I called windows tech sup port - they were completely unhelpful and told me to talk to hp

  I went to h p sup port: I did a scan of the missing drivers and found I was missing an update of the BIOS. I installed it and it seemed to help at first, but the probblem remains.

  I think that there is a driver, or something on windows which is corruppted, or else I have a virus that is very well hidden. Unfortunettly my simptems aren't enough destinct for google - able. Is their no way to deal with this, without having to reinstall windows?

  In addition, you seem to be able to pass Windows 7 ro 8 without losing data (or vista to 7), can do you a re - install any without losing files. If I have to reinstall some programs it is very good. I know it must be something that I ask micrcosoft, but as I said they were completely useless and told me to check with hp.

  Hello Wigmy.  I understand that you are having problems related to slowdowns, ultimately makes the phone unusable.  Is this correct?

  Honestly, it seems you did a very good job to go beyond the usual suspects.  You did a scan for viruses and malware, with no luck.  Make sure that all drivers are up to date, and who had no effect.  You also tested the memory, and it passed.

  I see a little more possibilities here.  A possibility is that the hard disk contains errors, then you will want to check that as well.  Another possibility and one who seems more likely to me is that some of the system of the operating system files are damaged or that you are indeed infected with a stealth virus.  I think that this second option is the culprit, due to the fact that the laptop works very well when it is started in safe mode.

  First, make sure that the disk hard past the built in hard drive test.

  1. Reboot the laptop.
  2. Until the BIOS loads, press F10.
  3. Under Diagnostic Tools Select Hard Drive Test and let it run.
  4. Display the result.

  Once we exclude the corruption/problems with the hard disk, the next step will be to do a full recovery of the machine.  , You will lose all data that you do not back up.  The Recovery Manager will be an option allowing you to back up your files.  However, you can start in safe mode and save a USB key or external hard drive as well.

  Here are the steps for recovery.

  1. Restart the PC.
  2. Press F11 during boot up until the Recovery Manager starts to load.
  3. Select "System Recovery" and follow the instructions.
  4. Allow the recovery complete and verify that this solves the problem.
  5. Display the result.

  I hope you find this useful!

• Pavilion x 2 detachable 10 ": the quality of sound on audio jack output

  The sound quality on the audio 1/8 "jack to an external system that is, use a mp3 player is terrible. Low frequencies are cruelly and it is not unlike an old transistor radio. While perhaps marginally acceptable with a helmet style earplugs, playing through an external system is not.

  There seems to be not having only one choice of audio driver for this system, and it is updated by the press on the system. Is there another available pilot or something else I could try to improve the quality at least at the level of a mediocre mp3 player? Or is there something faulty with the material?

  The main use for this system has been like an audio player. Its size USB port size, complete for mini-USB and flash drive is seemingly perfect. I do not anticipate the lack of sound quality, so disappointing. I understand this laptop is not audio high-end, but my sound quality of the phone going circles around it, that something seems not quite. I am playing not even .mp3, .wav files and uses 2 different players with the same results.

  Any recommendations would be greatly appreciated.

  You can mark this message as 'Solution' which makes it more important in research and Internet feeds, so more people will see if the suggestion to use the usb external sound card has been beneficial. I am pleased to have been of assistance.

• Questions about the frequency step response

  Hello

  I use the Signal Express 3.0. I'm not clear on the transfer functions in step of frequency response with different modes of calculation of the average. What I got from the help file is this H (f) = Sab (f) /Saa (f) which is cross the frequencies on the spectrum auto where is the pulse and b the signal response signal. When the mean quadratic value is used, I wonder if the transfer function becomes greatness of cross spectrum divided by the magnitude of the spectrum of the car. When an average of vector is, everthing is used in complex numbers. He averaged temporal signals, frequency domain signals, or the results of transfer functions?

  Thank you very much.

  The algorithm to calculate the spectrum is the same in both modes.  However, the method of calculation of the average can have a huge impact on the outcome.  Mean quadratic value is performed on the spectrum itself, after the calculation.  Vector averaging is done on the input signals before the calculation.  With an average of vector signals must be consistent (have the same phase) or the result will be bad due to the signal being on average by far.

• Questions about an average of response spectrum and frequency of feeding mode.

  Hello

  I have a few questions about an average of mode. When I generate a sinusoidal signal from one output to two input channels channel to see if my DAQ card works well and vector averaged in the power spectrum for DFT, the amplitudes was different from the previous one of the amplitude, which was supposed to be 1 v peak. They range from 0.5 v to 0.6 v peak. When the calculation of the average model is RMS, the amplitudes were close to 1. I wonder what are the fomulas of RMS and average vector. Does that mean that I could not accurate if I use an average of vector? In a time of frequency response, why I coherences of difference and the amplitudes using the vector and the mean quadratic value?

  Thank you

  Ningyu

  rico1985,

  The differences in modes of generation are as they sound: 1 sample output only a sample writing, N samples will be released however many samples configure you for each entry, and the continuous samples released samples continuously until a specified user action happens (you press the stop button or a logic that you created gets fulfulled). The range of Signal output allows you to set a ceiling high and low level of your output signal and it only affects the quality keeping in this beach. Timing to set a deadline for the time between the acquisition of the sample. If a new sample becomes unavailable before the timeout setting, you will get an error. This is useful for looking at a network, because if the network goes down and you stop getting data from a machine and then you would like to know about it. I point you to those videos that are short tutorials on how to make the most of these actions in SignalExpress.The SignalExpress 3.0 Help file is also your first point of contact for all your questions on getting started. These two resources should get you up and running in SignalExpress in no time. (either by the way all your questions answered using these resources) Bravo!

• Response frequency (simplified answer)

  Hi guys, I would like to use this method (this appears as an example vi) to determine the frequency response of my system with my input signal (no answer: square wave) I'll first need to "pull" the impulse response. Can someone explain what 'pull' means on this occasion. In the example, it uses a call to the library, but I need more details.                                                                                                             Thank you, ds1
