That are the ones that have a mosquito ring tone on the phones so the
teacher cannot hear it.
I've heard this one and have my doubts that a phone speaker has either
the
frequency response or power to reproduce this properly.
We were thinking that at work. Still, you cannot stop made up stories from
doing the rounds.
I downloaded a wave file and played it on the rather tinny speakers of a
laptop and I couldn't hear it but my daughter was going to chuck the laptop
out the windows after 30 seconds.. she was 21 at the time. I expect that it
would work as a ring tone.
I would have though cheap and tinny were the perfect pitches for
mosquito coasters.
