Is it really true that alot of people start listening to softer music as they get older because of their ears?

Alot of relatives of mine loved bands like Boston and Led Zeppelin
when they were younger. Now they never listen to them anymore. They
listen to Blues and soft rock, or country.

Is it because they think that the bands they listened to when they
were young, are too loud for them nowdays?
@ Gork, I think you are wrong. Whenever you go to a get together or a
place that has alot of older people, most of the time they have the
music on at soft volume. Whenever the music is too loud, most older
people want it turned down.
