How much does the volume change while rolling through the middle range? To play a constant tone, click Play or press Space. All of these tools generate a series of tones from your computer and then measure the volume (SPL) of those tones using the microphone. Note that at the bottom and top of the range your speakers may not be able to reproduce the sound, especially if they’ have smaller drivers—like the one on your cell phone’s primary body speaker. This is necessary so that the microphone can pick up the signal from all of the drivers. It will make things a lot easier. Disconnect any subwoofer and turn off any filters in the receiver before starting your testing. You could also use a DisplayPort or HDMI connector if your stereo supports it. The highest level (and most expensive version) allows for 24 measurements per octave. An inexpensive voltmeter can measure levels at speaker terminals, and other points in the signal chain. Call our tech support line at 1-800-CALL-MTX if … Cheaper speakers are able to achieve this over a small portion of 20-20,000Hz, while better speakers can achieve this over greater portions of 20-20,000Hz. Try this video on several devices and you’ll quickly hear the differences from one speaker to the next. You will also need software that generates test tones at different frequencies and then reads back those tones using the microphone connected to the computer. For fun, here are a few frequencies to help connect these numbers to real life sounds: Reviews and pictures of amazing speakers can be found at Stereophile.com. The 60 second online subwoofer test. ETF has a free demo that should do everything you need. Use a laptop for speaker testing if you have one. The different recording levels are designed to give you the perfect gain match for your application. How to use TrueRTA: There are 4 levels of TrueRTA. How it works: You listen to a series of test tones and identify the frequency of each one as you go. The video above runs through the spectrum of sound from 20Hz all the way up to 20KHz. I would give it five stars if it had 1/3 octave test tones from 20 to 18,000 hz. Do that by placing your speaker where you plan to put it permanently, and placing your mic in the place where you’d be listening. If you don't have a microphone for testing, you may want to build your own instead of spending a lot of money for one. For free software I recommend AUDio MEasurement System (AUDMES). Alternatively, you can test where the speaker will perform best before placing it. You will not be able to hold it steady enough. This test isn’t always scientific. First of the test signals boink.mp3 is a collection of tones at individual frequencies. If not, you can select/change your Input/Output devices from the Tools->Select Sound Card menu option. Simply tap on the sound wave icon and pick between sine, square, sawtooth or triangle. It will not cause lots of random narrow spikes in your tests, so it can be used to try to find any spikes in a response curve. In the Tones Files section you will find audio files ranging from 20 Hz to 20 KHz. To see how speakers work, this animation is extremely helpful for grasping the basics: How Speakers Make Sound, 16Hz – The lowest note on large organs (low C on a 32′ stop), 20Hz – “The lowest people can hear” (not strictly true, but this is an intro…), 32Hz – The lowest note on many church organs (low C on a 16′ stop), 65Hz – Very deep bass singers can sing this note, 1000Hz – Very high sopranos can sing fundamental frequencies in this range, 3500Hz – Fundamental frequency of the highest note on a harp, 8372Hz – Fundamental frequency of the highest note on an organ (high C on a 2′ stop). (Amplitude / Computer Volume) on the right side of the screen from -10dB to 0dB. How to use AUDMES: This tool is very easy to use. From the top right of the popup window, click Level Check to check the sound level. These frequencies range from 100 to 15000 Hz. Speaker Testing and Analysis Now that you have built your speakers, it is time to test them. It takes about a minute to run each test. In fact, turn the volume all the way up just for checking: your speakers might be working but playing weak sound. Frequencies lower than 20 Hz are beyond our frequency hearing range: our low frequency response test - which starts as low as 10 Hz - should remain inaudible until it reaches 20 Hz. However, most important characteristics (like smooth frequency response and centering) can be estimated by ear. Speaker cleaner app is a very simple frequency generator which generates different frequencies and performs a sound test and audio test on your speakers. At the beginner level you are tested on four different frequencies, then you can work your way up to guru level with all 31 frequencies. The frequencies in this signal are 16, 18, 20, 22, 26, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 120 and 150Hz. Try reversing polarity (swap + & -) on one of the drivers to see if the dip goes away. If you are testing a single driver, then place the microphone right in front of the driver, centered on the cone and aimed directly at the driver. If you find a sound system that you like, remember, although ‘flat’ means accurate reproduction, it does not necessarily mean that you will like how it sounds when listening to music/audio that you are familiar with. Place the speaker off the floor and away from any walls (including behind the speaker). As review, we can look again at the spectrum of white noise (equal energy per unit hertz) versus pink noise (equal energy per unit octave) below. Low Frequency Response and Subwoofer Audio Test (10-200 Hz) Subwoofer Kick Test. Now that you have built your speakers, it is time to test them. Download 1kHz Left Channel. With an uncalibrated microphone you can still design a series or parallel notch filter, but you should not add a contour network based on results from an uncalibrated microphone. Click the play button below to begin the test. Frequency based Speaker Analyzer It generates a simple sine wave frequencies which will let you test the quality of any kind of speakers, internal or external. Mosquito Tone Audibility Test (17.4 kHz) Place the microphone in front of the speaker. With every tool, you should first raise the volume of your computer and lower the volume of both the stereo/receiver. Do not try to hold the microphone in place with your hand. Make sure that you don't have any active crossovers or equalizers enabled if you are using a receiver. This test can be done with speakers you have constructed or ones you buy off the shelf. If you still want to purchase a calibrated microphone, check out the combined calibrated microphone + software deal from True Audio. It should sound like it comes from thecenter of the monitor if you balance control is set correctly. To give your speakers a quick test, hit play on the video: Do your speakers sound evenly from bottom to top? There is a free version of TrueRTA, but it can only take 1 measurement per dB which is not adequate for real speaker testing. Most of this error is above 4kHz and is a soft error.
