Yes, low level sound over an extended period will also damage your
hearing. The background noise in a server room, for instance.

It takes a while for the damage to occur, and it's not absolute. Less
acute hearing doesn't mean total deafness.

There are many different kinds of hearing loss that come under the term
"industrial deafness". Ringing in the ears is one kind. Near total loss
at specific frequencies is another. Partial loss across many frequencies
is another again.
