Beware Absorption Myths
Tip: Highlight text to annotate itX
Today I'd like to talk about some of the myths that go along with room acoustic products.
There's a lot of them out there and I'm just trying to get you to do your own thinking.
Not the manufacturers' thinking, do your own thinking when it comes to acoustical products.
In front of me I have four bales. Each bale is about a foot and half wide. This is a common
sound absorbing material used by professional studios, project studios, amateurs in listening
rooms across the world.
And to absorb, let's just use an example so you can kind of get a feel of what we are
talking about here and you can use this information when you see a claim made by a manufacturer,
to absorb a 100% at 185 cycles or 185 Hz, you will need 6 ft. You would need all of
these material in front of you. So if you see a manufacturer claim they are absorbing
a 100% of a certain frequency and their cabinet is only this thick you need to be a little
bit cautious. You need to say to yourself, "Oh wait a minute, it takes a lot of sound
absorbing material to absorb a 100% of anything." So look at the test results, make sure it's
verifiable. The laws of physics can be bent but they cannot be broken.
