Will sound pass through well? I'm looking for a replacement foam speaker cover (intercom). Currently it's 3/4" to 1" thick (could be less thick).

read previous answer. Media will pass air for cooling circulation, and would pass sound as well. How well it would pass sound, I can't determine from my application.

is anyone using this as PC dust filters? saw same product on youtube and guy said it was not affecting air flow?

Yes, on the air intake for a rack mounted power amp. It works well.

When you hold this 30 ppi filter up to the light, can you see through it? thank you.

I can see specs of light through it, but I cannot see what is on the other side. It is opaque but lets specs of light through.

Would this work for my ventless whirlpool dryer bottom filter?

That's a question to ask a Whirlpool dealer.
