    E, Bb and B on my bass guitar sound "boomy"

    Sign in to disable this ad
    When i play E (open) Bb and B on my low E string they sound incredibly bassy and not warm and round like the other notes. I tested it through headphones and they sound fine, so i have to assume the problem is in my room acoustics, right?

    I'm in a small square room 2620mm W 2950mm D 2660 H (8'7x9'8x8'7 approx). I've two acoustic foam panels, one on my left wall (when facing speakers/computer) and one behind my computer. I guess my logic was to not deaden the room totally, but control a portion of the reflection.

    I find it interesting that 3 notes on my bottom string resound stronger than the rest when played at the same velocity.

    I read in mixing with your mind, when finding where to set up drums in a room to record you can use the floor tom and walk around to dif parts beating the drum to find where certain frequencies resonate, how would i apply that to finding how to acoustically treat my room? Is that even possible? Can i put foam in certain places so that those notes on my bass won't resound louder than the rest?

    Any help/advice you're able to offer is greatly appreciated

    You need bass trapping, not foam. And LOTS of it a room that size.

    All four corners, floor-to-8' high at a minimum. You could triple that (upper corners where the wall meets the ceiling and where the floor meets the wall) and it wouldn't be too much.

    A few sites that have very usable information -

    www.realtraps.com
    www.gikacoustics.com

    and a neighbor of yours -

    www.johnlsayers.com Some very nice "DIY" corner traps there that might be right up your alley.

    This seems obvious now... so small room = ultra reflective as their is nowhere for the frequencies to go except round and round?

    Is this what you mean by bass trap?

    More like GIK 244's or RealTraps. Foam isn't dense enough (and in that case, large enough) to really hit the spot.
