Sound insulation and perfect acoustics for concert halls and function rooms

What are the challenges for sound insulation in concert halls and function rooms?

The light in the room goes off, the stage or podium is lit, the public listens excitedly. Now comes the decisive moment when perfection is required – not just from the musicians, artists and speakers, but also from the acoustics in the function room.

Typically there are two factors that the critical for optimum acoustics with regard to sound insulation in function rooms and concert halls: Firstly, the insulating sound from the outside, or insulating noise inside, and secondly improving the sound in the room.

The perfect acoustics for the great moment on the stage – without echoes, reverberations, noise and disturbing sounds. Sound absorbers improve the acoustics in the concert hall or in the function room and ensure great sound moments.

How can the acoustics in the concert hall or function room be improved?

Large floor areas and high ceilings: Two features, which frequently cause poor acoustics and noise in concert halls. The sound spreads unhindered and even quiet tones and noises cause distorted echoes. In order to prevent this and for a targeted influence on the room sound, sound absorbers are used for sound dampening. Unpleasant reverberations, echoes and bass drumming are prevented and the spectators can enjoy the events in full.

Sound absorbers against problems with flatter echoes and reverberations

Flatter echoes, which occur due to long reverberation times due to unwanted sound reflections from wall and ceiling surfaces, should be dampened with sound absorbers. aixFOAM sound dampening mats can be fitted as broadband absorbers on walls and ceilings.

For large spaces with high ceilings, free-handing sound absorbers with suspension or cable systems, as well as acoustic sails beneath the ceiling, are possible. They absorb disruptive sounds and frequencies and reduce reverberation.

Profiled sound absorbers, like the classic nubbed foam or pyramid foam, disperse incident sound as well and thus ensure a particularly natural and pleasant sound.

In order to avoid "over-dampening" and unnatural acoustics, you should proceed gradually and first start with a smaller quantity of sound absorbers.

Clear the stage – for good acoustics in the function room or concert hall. aixFOAM sound absorbers improve the room acoustics and the sound and voice quality. As a result, the spectators can listen to and follow the events without problems.

How does the soundproofing work in the concert hall and function room?

The soundproofing in concert halls and function rooms should prevent noise from outside (street noise, train noise, plane noise, etc.) from entering the room and disturbing the concerts and events. Additionally, noises should not escape from the room or hall and thus become an issue for the surrounding area. This is important above all in locations in residential areas or for buildings where several halls have performances at the same time.

Soundproofing the wall and ceiling

If sound insulation is not taken sufficiently into account during the construction of the event building, subsequent soundproofing actions are needed. Depending on the sound pressure level and the location of source of the noise or sound, structural measures are necessary in order to effectively soundproof the walls and ceilings of the hall.

Extensive information and detailed instructions about soundproofing walls and ceilings can be found in our aixFOAM knowledge article (German).

Which role does fire protection play when selecting the sound absorbers for concert halls and function rooms?

Selecting the right sound absorbers for concert halls and function rooms is critically determined by the required fire protection provisions for these premises. aixFOAM sound absorbers are available in various fire protection classes. The absorbers with the designation "MH" in our "Architect Line" are certified, e.g. according to fire protection directive DIN4102 B1, which typically applies to public and commercial buildings.
