A reliable sound insulation and good acoustics without disturbing noises, flatter echoes or overlying frequencies are a must for perfect recordings in the sound studio.
In general, there are two challenges related to sound insulation for recording studios, which are critical for a precise, professional sound: Firstly, the insulating sound from the outside, or insulating noise inside, and secondly improving acoustics in the studio.
For sound dampening or even sound insulation for sound studios and rehearsal rooms, the important thing is to prevent noise from entering the room and disrupting the sensitive sound recordings. In addition, noises should not escape from the studio and thus become an issue for the neighbours.
In order to prevent walls, floors and ceilings vibrating as a result of the sound, and thus emitting noise into the surroundings, the mass of these elements should be increased by installing sound insulation. This reduces material vibrations and prevents sound propagation.
Profiled sound insulation mats such as nubbed foam or pyramid foam are not suitable for this form of sound absorption because of their low mass. We therefore recommend using acoustic elements with a high material density, e.g. acoustic heavy form, heavy acoustic foil or, ideally, a combination of both acoustic elements.
Another very effective possibility for preventing the transmission of structure-borne sound through walls and ceilings is decoupling using so-called room-in-room concepts. Partition walls are placed in front of the walls of the room. This creates an air cushion between the two walls, which already weakens the noise level. The space should be filled with sound absorbers in order to completely block the sound. We recommend sound insulation elements here with a high density (heavy acoustic foil, heavy acoustic foam) or sound absorbers with a flat surface with the largest possible thickness. The floor of the sound studio should also be "floating" so that sound transmission is prevented.
To improve the sound in the sound studio or rehearsal room, the sound in the room has to be dampened selectively. Acoustic foam sound absorbers are particularly well suited for this. The open-pore foam allows the sound to penetrate deep into it and absorbs it. As a result, unwanted reverberation is reduced and the overlying of frequencies is prevented.
The stronger (thicker) the material of the absorber or insulation panel, the lower the frequencies that can be dampened. Bass absorbers or bass traps are therefore typically particularly thick.
The first step towards sound dampening in the sound studio is typically to install sound insulation panels as broadband absorbers on walls and ceilings. This prevents sound reflection and reduces reverberation times.
Foams with surface profiles, such as the classic nubbed foam or pyramid foam not only absorb unwanted frequencies but also disperse the sound. As a result, the composition and quality of the reverberation is changed, creating a more pleasant and very natural sound.
In general it is recommended to proceed gradually with sound dampening in the sound studio. If sound absorbers are arranged over too large an area, this quickly leads to "over dampening" and an unnatural sound. Mostly it is sufficient to cover 20 – 30% of the wall and ceiling area with acoustic elements. This improves the sound and at the same time is less expensive.
Sound dampening of drums in the rehearsal room or sound studio represents a challenge because a particularly large amount of structure-borne sound is generated when playing them, which is transferred into the floor. It is therefore advisable to decouple the drums from the floor. This is succeeded best by placing the drums on a small riser. Like the walls and ceilings, the platform should also be filled with heavy acoustic foam or heavy acoustic foil and be covered with a "floating" wooden panel. This blocks sound transmission. In addition, we recommend placing suspended acoustic elements above the drums. The aixFOAM sound absorbers in aluminium hanging cassettes or ceiling sails are particularly good for this.
As a manufacturer of high-quality acoustic foam sound insulation elements, we at aixFOAM know how important but also challenging the subject of the sound insulation is for the sound studio. The sensitive microphones pick up every sound – disturbing noise loses nothing here! In our online shop you can choose the right solution for optimum studio acoustics from various sound absorbers or get free advice from our experts.
Thanks to 60 years of experience and constant optimisation of our high-quality acoustic foams, we have succeeded in developing flexible and simultaneously stylish sound insulation elements with high absorption coefficients. aixFOAM sound absorbers reduce noise, improve the sound and are available in various fire protection classes and material thicknesses. Choose your favourites from several colours and surfaces. Different installation options, such as our self-adhesive kit, make installing the sound absorbers easier or like out hanging cassettes provide visual highlights.
