Film fans and music lovers know and love the moment when the first tone sounds in the home cinema or HiFi room. One thing is critical here now – The perfect sound! However, the high quality speakers and expensive HiFi or sound system are frequently disappointing after they have been erected. Why is their sound not as good as expected, but instead only produce a muddy, humming sound?
The reason is the poor room acoustics in the home cinema or music room, which can be improved by using sound insulation. However, a distinction has to be made here between the insulating of sound from the outside and soundproofing in order to improve the acoustics in a room.
The film experience in the home cinema becomes a pleasure thanks to sound insulation. Sound absorbers help improve the acoustics in the room and achieve the full effect of the sound from the sound system or HiFi system.
How does the soundproofing or sound insulation work in the home cinema?
When the tension in the film reaches its climax, a powerful sound rounds off the sound entertainment. However, out of consideration for the neighbours, the family or other residents, targeted sound insulation measures should be taken. The point of soundproofing or sound insulation in the home cinema above all is to prevent the transfer of noise to the outside.
Heavyweights stop noise in the home cinema
If the sound pressure level increases, ceilings and walls in the home cinema start to vibrate and transfer noise to adjacent rooms. To prevent this, it is necessary to strengthen the material of these construction elements. This is only successful with a decent mass. Sound insulation mats with a profiled surface, such as pyramid foam or nubbed foam are flyweights and therefore are not recommended.
Acoustic elements with a high material density, such as heavy acoustic foam, heavy acoustic foil, or a combination of both absorbers are ideal for strengthening walls and ceilings and for blocking sound transmission.
Room-in-room concepts prevent sound transmission
To prevent the transfer of structure-borne sound and to reduce noise as much as possible, we recommend using so-called room-in-room solutions. For this, a second wall – for example made from drywall – is placed in front of the room's actual wall. The space between these walls should then be filled with sound absorbers. Sound insulation elements with a high intrinsic weight (heavy acoustic foil, heavy foam) or sound absorbers with a smooth surface and a strong thickness are ideal here. The thicker the material of the selected absorber, the more sound that is swallowed and absorbed. Cladding the wall construction with acoustic material completes the cinema-look and ensures an elegant ambience.
A "floating" floor is recommended for decoupling in order to prevent noise transmission. Windows and doors can also be subsequently insulated. More information about this can be found in our aixFOAM knowledge area (German).

Sound insulation or soundproofing of walls and ceilings in the home cinema prevents arguments with the neighbours – for undisturbed film enjoyment.
How can sound insulation improve poor room acoustics in a home cinema or music room?
To improve the acoustics in the room, various sound absorbers are used to dampen the sound. As a result, bass humming or flatter echoes are prevented and the system and the speakers can realise their full sound potential.
Sound absorbers for problems with high frequencies and flatter echoes
Shrill-sounding highs or flatter echoes, which are created by long reverberation times and unwanted sound reflections, should be dampened with absorbers made from acoustic foam. Profiled sound absorbers such as the traditional nubbed foam or pyramid foam can be fitted as broadband absorbers on walls and ceilings in the room. They absorb disruptive frequencies and reduce reverberation. The profiled surface disperses the sound as well and ensures a natural sound.
Typically, covering 20 – 30% of the wall or ceiling surface with absorbers is sufficient. They should be fitted gradually in order to prevent "over dampening" and an unnatural sound in the room.
Sound absorbers such as nubbed foam on the walls of the home cinema as broadband absorbers reduce reverberation and remove flatter echoes – for the perfect film sound
Bass absorbers for problems with bass booms or bass humming
In order to dampen low frequencies and bases, so-called bass traps or absorbers made from thick foam are used. Alongside panel absorbers, bass absorbers or even low tone absorbers are particularly effective. They are pyramid-shaped and should be placed in the corners, with the points facing the room. This installation is also why they are called corner or edge absorbers.
