Hearing changes, becomes desensitized.
Also, I would rather have people give up (geez, I have to listen to silence
or play a beep speed test (with seconds of silence between chirps) rather then

Insert tests that people will obviously 'fail' if their hearing or equipment
is totally shot or they are operating carelessly or they are trying to
pollute the sample set.

(I.e. masking tests where no masking could logically be occuring)
