Test your hearing knowledge of the entire range of human hearing...

a quintessential asset for all audio engineers.

This is a quiz that has you hear frequencies ranging from 20 Hz to 20000 Hz.

You'll guess which frequency it is, and get a certain number of points depending on

how close you were. Each frequency tested is a generated sine wave, corresponding to a 31-band EQ.

Use with care; make sure that you turn the volume to a reasonable level to prevent hearing damage.

Try getting 440 points or above for a special treat! (440 Hz is the note that Orchestras tune to.)

Scoring System: 100 pts for the correct answer, -10 pts for each interval away you are away from the correct answer.

Disclaimer: Please use headphones with a frequency response of 20Hz to 20000Hz for the best results, as

your android device may not be able to play all of the frequencies in this range with its built-in speakers.
