Frequency range for human ear

[danroll]

does anyone know where i can find a diagram showing the frequency range for the human ear??

Its generally quoted as 20Hz to 20kHz.

I typed this:

into google, and got this:

My answer from body and soul:

Normal hearing range for children/adolescents is around 20Hz to 20,000Hz. As you get older the hair cells in the cochlea get damaged or destroyed - this usually affects the hair cells that deal with high frequency sounds first ( as they are neared the "entrance" to the cochlea ). So most people will lose these high frequency sounds first. I test hearing for a living - and it is not very uncommon for people in their 80's to not hear anything above 6,000Hz.



My father-in-law has quite bad noise damage to his hearing - and he has normal (less than 20dBHL threshold) hearing to 4,000Hz - and then no measurable hearing at higher frequencies.



N.B. the description of cochlear function in the first paragraph is VERY simplified.

Odd, this was in my physics exam today.

very odd indeed

It was part of a question about ultrasound.
