Sine Sweep - Full Spectrum (20 Hz - 20 kHz) - Audio Check
https://www.audiocheck.net/testtones_sinesweep20-20k.php
These audio files scan all audible frequencies from 20 Hz to 20 kHz in a 20 second time span. When the time scale is logarithmic, sweeping between 20 Hz and 40 Hz (one octave) or from 10 kHz to 20 kHz (one octave) will take the same time. When the time scale is linear, sweeping from 20 Hz to 40 Hz will be much faster, and equal to the time ...

In a study by James Boyk at Caltech Ref 1, he found that 68% of the sound energy of a. bunch of keys jangling resided above 20kHz. Of musical instruments, a crash cymbal has 40% of its energy above 20kHz and. harmonics are visible to above 102kHz (which is the upper frequency limit of the. study).

The vibrations that create a sound at 20 hertz are very low—a bass rumble—and have a long wavelength. It’s vibrating the driver twenty times every second. Most music and audio plays in the range of about 80 hertz to 15,0000 hertz. At 15,000 hertz the pitch is a high whine due to its extremely short wavelength, like a smoke detector alarm.

Files being tested. The first one plays back full range white noise, with frequencies extending up to 22 kHz. The second file plays back a low-pass filtered noise, with no sonic content above 20 kHz. Listen to both files: if you think you can hear a difference try the test below, otherwise pick a lower cutoff frequency at the top of this column.
