Whats the difference between High frequency and Low frequency hearing loss?

Question

Answer 1

Sound occurs over a wide spectrum of frequencies.  The human ear is sensitive to a frequency band withing that spectrum.  Since sounds occur at different frequencies, you will not be able to hear the sounds at the high end.  The frequency that dogs can hear covers a different range.  That is why a dog can respond to a human voice, but also to a silent dog whistle which is too high of a frequency for humans.  The most common frequency hearing loss for men is the same frequency that their wives speak.
