Question: Which way should I turn a foam ‘mattress’ on a door for temporary soundproofing, grooves to door or vice versa


Question by esha26: Which way should I turn a foam ‘mattress’ on a door for temporary soundproofing, grooves to door or vice versa
I notice in sound studios the grooves are toward the room. So, if I’m trying to keep hallway noise out of a room, I’m thinking grooves should be turned towards the door. What do you think?

Grooves towards the door.

    Grooves toward the room to deflect and absorb the sound.

    Hi Slither – You’re doing some creative thinking; good for you. When my brother and I were in a band together and yes, practiced in a garage, we tried the set-up both ways and it was most effective for sound-proofing to have the grooves facing into the room. We even had padding on the ceiling because our drummer would get carried away with drum solos. (Santana started out as a garage band, just down the street, in San Mateo, CA!) If you are trying to mask the sounds from (the noisy neighbors) next door, and already have the grooves facing outward/toward the wall to absorb outside sounds, you’ll find you have to have the “grooves” facing inward just so it’s a flat-to-flat surface, or the mattress may keep flopping over. Experiment and see what works best for you.

    We ended up tacking material over the mattresses, so it provided a little more atmosphere/appeal.

    All that being said, according to http://www.soundproofing.org, it helps to have padding/grooves on BOTH the side(s) facing outward AND the side facing inward. According to this website, they suggest soundproofing caulk, a 3″ dead-air space, and a few other things because your project involves both noise absorption, as well as noise blocking, and it explains how to do it all. I’m glad you asked; I learned a few things, too.

    Best of luck!

    If you have the grooves toward the door it will give you a little more acoustic dampening.

    your right, but really a foam mattress should knock down sound either way, because the “grooves” as you put them are against a flat surface and the door is reflecting off a flat surface so it shouldnt make any difference

    The grooves should be towards the room. The grooves serve the purpose of reducing out of phase echo tha bounces off the walls. It’s not really soundproofing though. For soundproofing the grooves don’t matter much. Put soundproofing on the ceiling too, because the ceiling acts like a drum and transmits the bass frequencies.
