Architecture and the interior are not the only critical components for a relaxing atmosphere in your own four walls, but also the acoustics. The room acoustics in the living rooms and home affect communication and the quality of the accommodation considerably and can be improved by the targeted use of sound insulation.
There are mostly two different causes of poor or unpleasant room acoustics. Direct noise can be one disturbing factor, another can be unwanted reverberation or excessive reverberation times.
A high noise level or sound pressure level describes the dominant volume in a room. If this is particularly high, noises quickly become a problem. The noise source here may be outside the room or the building, e.g. loud noises from the neighbourhood or traffic noise. The noise source may also be in the building, e.g. a juddering washing machine can cause noise. In any case: Once the noise source is known, targeted measures for sound insulation and soundproofing can be taken.
Reverberation describes how long noises remain in the room after the source of the sound has been switched off. This time is call the reverberation time. In modern architecture, visually elegant, but sound-hard materials such as glass, concrete and hard woods are used. These surfaces reflect incident sound, thus increasing the reverberation time, and ensure that noises sort of get stuck in the room.
If there are many noise sources in a room, there is often an overlaying of multiple frequencies. As a result this creates a sort of "noise stew", which not only makes hearing and understanding uncomfortable, it even makes it impossible.
By installing sound absorbers on walls and ceilings, the reverberation can be reduced and the room acoustics in the home or building can be improved.
In order to stop noise transmission in a home or a building, it is necessary to shield off the noise source. To do this, the walls, ceilings and floors can be fitted with sound insulation mats. Flat sound absorbers with a high intrinsic weight and a high material thickness are best for this, e.g. sound insulation panels made from heavy acoustic foam.
Sound insulation on walls and ceilings can prevent noise from outside entering a room or a building, but can also preventing noises escaping from inside to outside. This is sensible, above all, if you want to avoid problems with neighbours or prevent disturbing noise such as traffic noise.
So-called room-in-room concepts for decoupling building elements in particular have proven themselves in practice. This soundproofing method prevent walls and ceilings becoming sound conductors. We have summarised the most important factors and instructions for soundproofing in our aixFOAM knowledge article "Soundproofing wall and ceiling" (German).
Footstep dampening has a very special place in the area of soundproofing. Footstep noise is a specific form of structure-borne sound and is not caused by air vibrations hitting a solid body and then passing through it, but instead by the impact of two solid bodies. Supposedly light steps can quickly become an annoying plague for neighbours in the apartment below.
Especially with modern parquet and laminate floorings, the right choice of insulating underlay can be critical. There are different possibilities here, such as laying rolled products, but also heavy acoustic foam panels are footstep dampening beneath the pressure distribution layer in the floor.
Retrofitting soundproofing on windows and doors is a particular challenge. Unlike the solid brickwork of buildings, these construction elements vibrate easily when air-borne sound (street noise, music, etc.) hits them and they become sound conductors. The retrofitting of sound absorbers can be a good alternative here to the relatively price-intensive sound insulation windows and doors. In our aixFOAM knowledge area (German) you will find extensive articles (German) about sound insulation on windows and doors and instructions for DIY solutions.
Acoustic foam sound absorbers are excellent for improving the room acoustics in the home or in the building. The material of the porous absorbers allows sound waves to penetrate deep into the acoustic elements and absorbs disturbing frequencies.
By fitting absorbers on hard surfaces such as walls and ceilings, the reverberation if reduced by targeted sound dampening. Typically, in order to lower the noise level and create a pleasant climate, it is enough if 20 – 30 % of the wall area of the room is fitted with absorbers.
In addition, we know from experience that it is sensible to proceed gradually with the sound dampening to find the optimum room acoustics. This not only prevents "over-dampening" and thus unpleasant artificial acoustics in the home, it also saves money.
Alongside traditional acoustic absorbers for walls and ceilings, acoustic sails or free-standing acoustic elements offer another alternative for sound insulation indoors.
For acoustics for well-being and relaxation, you need a professional sound insulation partner. As a manufacturer with 60 years' experience, we make high quality sound absorbers "Made in Germany" and know what is critical for good room acoustics. Through constant further development of our products, and with an open ear for the needs of our customers, we have succeeded in combining effective sound absorbers with attractive designs.
