>You exposed your ignorance in basic audiometry. The spoken voice  frequency content is 
in the low range. The  loss it is the most common occurrence among  the elderly resulting in  
their inability to discriminate the words.<

Well, not exactly.

Spoken voice is indeed in the lower range, but consonants, particularly sibilants, which are 
essential for being able to hear conversational speech, are high range.  *That* is why 
people with high frequency hearing loss have difficulty with speech discrimination, which is 
exacerbated by background noise.  It's also the reason why singers on acoustic recordings 
are often unintelligible.

Anyone interested in their own hearing might want to visit one of the online sites that allows 
you to check, such as 

http://onlinetonegenerator.com/hearingtest.html

It's certainly not the same quality as a test performed by an audiologist in a proper setting, 
but it'll give you some idea.  Like it or not, some degree of high frequency hearing loss is 
virtually universal, as demonstrated here:
