With age we lost the ability to hear high frequencies. I’m 28 and I cannot hear frecuencies above 15KHz.
Here is a ringtone called ‘the mosquito’ which young people use for their cellphones to prevent adults from noticing that their cell phone is ringing. The ringtone frecuency is at 17KHz.
I’m curious to know if you can hear this ringtone or not: Please leave a comment on this post with your age(*) and let me know if you can hear it.
