What sounds get harder to hear with age?

Dr. David M. Vernick, MD
Ear, Nose & Throat (ENT Specialist)

As people age, their actual hearing for sounds decreases. They have the most difficulty hearing quiet, low-decibel sounds. But the loss usually isn't uniform across the frequency spectrum. People with age-related hearing loss usually have more trouble hearing high-frequency, low-decibel sounds like a hiss, a whisper or the "s" or "th" sounds that begin a word. Their hearing may be normal or close to normal in the low-frequency range, but moderate or worse in the high-frequency range.

Typically with age-related or noise-induced hearing loss, the damage occurs in the high frequency or high-pitched sounds, and those are the words that give meaning to the sentence or to what is being said. It's the high-frequency consonants that actually make the words mean something. So, if the phrase, "Please sit down on the chair," is said to someone who has a high-frequency hearing loss, they might hear something like, "Ease it own on uh air." It doesn't make any sense. That's because all the high-frequency consonants have been filtered out by the hearing loss. Hearing in the low pitches stays relatively good, so the vowel sounds in speech, A-E-I-O-U, are low-pitched and easy to understand and easy to hear.
