Selecting sound isolation

To work out my box-in-a-box I needed two types of materials: something “fluffy” for the walls, and something “strong” to carry the floor.

Reducing floor vibrations

Because our “music room” is on the first floor, I created a floor which is isolated from the real floor. To achieve this I needed a material which absorps vibrations and is strong enough to carry the weight of the floor and the drum.

I found such material on akoestiekwinkel.nl: Regufoam after reading this page on their site. I used type D150 which comes in the size of 50025025mm.

To be able to distribute the weight, these sheets of foam where cut in pieces of ±170*125mm. With an additional piece of MDF enough height was created to fill the remaining area with sound isolation.

Sound isolation for the walls

I mailed with eco-logisch.nl to ask them which product would be the best fit to isolate a drum booth and they suggested to use something with enough thickness: Metisse of 5cm.

To make sure most of the sound is kept inside the booth, the new floor and walls don’t touch the outer floor and walls = box-in-a-box. By leaving the walls uncovered the isolation can absorb the sound and avoid reflections, thus also reducing the level.
