Which one of the following frequencies of a wave in the air can be heard as an audible sound by the human ear? A. 100,000 Hz B. 0.10 Hz C. 10 Hz D. 1,000 Hz
Weegy: As a couple of people have pointed out, human hearing ranges from 20 Hz to 20,000 Hz, but as people get older and as they damage their hearing by listening to very loud music, firing guns without ear protection, [ working in very noisy environments or having other physical damage, that upper end drops off. At 64 yrs old, with a long history of a target shooter before we thought about ear protection, and after many years as a rock and roll disk jockey, I'm lucky to hear above 12,000 Hz on a good day! The guy going by who is rattling your car doors with his stereo will be as bad off as I am by the time he's 25 and in need of hearing aids by 50. ] (More)
