Please listen to the following media (FLAC) file. It will play a tone that moves from low to high.
Give your answer based on how far into the audio file you can hear before no sound comes out (ie, the timestamp, how many 'seconds' etc)
!!! WARNING: !!! Turn down your headset / speakers, and people with sensitive hearing / prone to headaches beware. The file is tuned to be quiet but the sound is considerably ear-piercing so proceed at your own risk.
