https://www.audiocheck.net/The MATT Test will assist in speaker and room treatment placement. The MATT test signal is the brainchild of acoustical engineer Art Noxon, president and founder of
Acoustic Sciences Corporation (ASC) and the inventor of the Tube Trap. The Matt Test was copyrighted in 1986 and converted to freeware on April 10, 2018.
MATT stands for Musical Articulation Test Tones. It was created to help the listener of an audio system to hear and measure the degrading effects of room acoustics on the audio signal. Later, after making some acoustic adjustments in the room, the improved listen-ability of the room can also be heard and measured. By recording the Before and After sound of the test at the listening position the A/B comparison is memorialized.
The original test is made up of a frequency sweep which ascends from 28 Hz to 780 Hz and descends back down to 28 Hz. The sweep signal is gated, turned on and off (50% duty cycle), at a rate of 8 times per second. Between each 1/16th second tone burst is a 1/16th second period of silence which is about 40 dB quieter than the tone burst in the test signal.
The basis of the test signal is a very slow sine wave sweep that is turned on and off rapidly, as to produce a train of tone bursts at increasing and then decreasing frequencies, each burst being followed by silence. If you listen to the test signal over headphones you will hear what the fully articulated or dynamic signal sounds like. Playing that same signal in a room will sound different. And, how different depends on the quality of your listening room.
As the frequency changes the MATT signal excites various reflections and resonant modes in your room that linger long enough that they fill sound into the silent portions of the MATT signal. This unwanted sonic lingering translates into a loss of articulation that is audible in poor rooms. A more detailed explanation on how the test works is available
here.
