Test your hearing range! A series of pure sinewave test tones covering the audio spectrum from 20 Hz to 22 KHz, each preceded by a vocal announcement giving the frequency of the following tone. Tones created in Cool Edit Pro. PLEASE:- 1) Download the file, don't try the test using the Freesound preview. 2) You need a decent quality sound card/interface or you may well be hearing false sub-harmonics at the top end of the test.

Note that the upper limit of human hearing falls rapidly with age. While people in their teens can hear 20,000 Hz, many older people cannot hear above 14,500 Hz.

Thanks! I needed test tones to deliver a physics of sound lesson to my k-12 students and this is perfect!

open the mp3 in Spek and you will see that it is a mono 128kbps at 44.1kHz, which the sampling rate by definition is capable of encoding up to 22050 hertz. you will see that all tones at various frequencies have the same decibel reading.
when encoding a song, yes, the cut off is around 18-20 kHz, but it is based on the audio as a whole, either a custom encoder option retains high frequencies, or the mp3 algorithm places more weight in the high end in this file specifically.

You are so right, swagsternigga
