ANR squeal on descent

I used to have a squeal problem with my DCs. Since I wear glasses, it
was suggested that the seal is compromised and feedback can occur. It's
been a long while since I've flown so I don't recall if that was in fact
the problem.

Denalis to deal with this but they say all ANR's do this.

My experience was just the opposite, compromise the seal to kill the
squeal... Wow, poetic...

I don't think it is. I asked the buyer and he says he wears his glasses
above the seals.
