I need to acoustically isolate my electronic drums and I need some help?
To start with I studied music tech at uni so understand the principles of acoustic isolation but I'm struggling to get this to work. My ELECTRONIC drum kit is in my loft conversion currently sitting on top of 70mm of chipboard which is resting on top of a sheet of laminate underlay (designed to stop foot fall transferring) and about 10-12mm of rubber matting. My thinking was that the chipboard acts as a dense floor which i isolated from th rest of the structure by the rubber and the underlay. Its failing miserably! In the rooms below you just get just the lowest frequencies but its louder there that in the loft! Any ideas on what else I can try would be really appreciated.
Just to make it really clear I am talking about an electronic drum kit and it is the sound of hitting it that is the problem (as opposed to having the amp up too high)
Answer:
The problem you have there is your cushioning medium is perfect for low resonance noise transfers (because it's solid) so you could fill the floor board gaps with foam or use a foam sheet instead of rubber as all the air bubbles effectively destroy the sound wave as in an Anechoic chamber, or get some heavy duty springs from a hardware store and set the chip board sitting on these on top of the rubber, this tends to kill all the noise from a vacuum pump i have in a similar set up.
