Music Rehearsal Room, Drum Room

The drums or musical instruments cover pretty much the whole range of the frequency scale from very low frequencies (bass drum, bass) to very high frequencies (hi-hats, guitars). The materials you require depends on what you want to achieve.

1. Optimising the interior acoustics

If you only want to attenuate the interior of the room to reduce the noise level for the player or persons who are in the room, it is best if you use foams (convoluted, pyramid or plane) which are at least 4 cm, but better still 6 cm or 7cm or more in thickness. The thicker the foam, the better even lower frequencies are absorbed. Thus a thickness of 4 cm is sufficient to attenuate snares, hi-hats and cymbals (or also guitars, etc.), but you require at least a thickness of 6 or 8 cm for bass so that you can audibly reduce the bass booming in the room.

In principle, you can choose any of our foams. You should choose our acoustic foam made of Basotect if you want very high-quality attenuation on the one hand and, on the other hand, if you want to use a bright, non-yellowing foam which will leave the room lighting bright and comfortable, or if you also attach importance to a high level of fire protection. If you are looking for a low-cost version, you can also use our 2 m² convoluted foam from our special offers (4 cm or 6 cm thick) or you can choose our more visually appealing pyramid foams. Our ester convoluted forms are often used too because they are of a very high quality and are also light grey and thus do not darken the room lighting too much.


2. Insulating outward music in other rooms

A significantly more expensive and more difficult solution is outward soundproofing!

Noise insulation is much more complicated than pure acoustic improvement or resonance removal. Please first read our information “Structure-borne sound and airborne sound” to understand how sound waves spread. Please do not use convoluted foam for noise insulation. Plane and heavy sheets are better in our opinion. First, you need to prevent the sound from hitting walls or ceilings directly. It should be absorbed in advance, for example, by the foam to prevent the masonry from vibrating. The lower the frequency of the sound source, the thicker the foam should be! We recommend our rebond foam  in this case. This foam is heavy and very well suited for noise insulations and is simply adhered with our mounting adhesive to the wall.
An even better construction is a 3-layer solution:
You mount on the wall, for example, first a 4 cm (or thicker) rebond foam sheet, then a heavy bitumen sheetand then again a rebond foam sheet. The bitumen sheet is available double-sided and self-adhesive so that only the first foam sheet has to be adhered to the wall! The thicker you choose this construction, the better our noise insulation turns out, particularly for low frequencies, but then the heavier it is and naturally the more expensive also! You may need additional mechanical fixing due to the weight.


How does this construction work?
The sound first hits the outer foam sheet, penetrates this in part and causes the bitumen sheet to vibrate. This bitumen sheet distributes the energy over the two foam sheets (thus on the front sheet and the sheet behind it. Thus only a fraction of the energy reaches the wall, depending on the thickness!


Very low frequencies, which you not only hear but also feel, are problematic! Often, for example, the amplifier or the bass drum of a drum set are directly on the floor! The floor also conducts the noises outwards via structure-borne sound (and even more or less around the foam on an insulated wall!). It is important to lay a thick carpet and to decouple relevant instruments from the floor: Build, for example, a platform with 8 cm absorber sheets and chipboard or a platform with rubber feet for the drums! Thus the structure-borne sound can be transferred only attenuated to the floor. The same applies for relevant amplifiers or other devices that vibrate.


However, it has often been seen in practice that medium and high frequencies are usually experienced as more disturbing - however, these are often well attenuated with medium foam thicknesses.
