Improve room acoustics – for more peace and well-being
Reverberation, high noise levels and poor speech intelligibility can quickly make rooms tiring. Sound absorbers on walls and ceilings absorb unwanted sound reflections and reduce reverberation time. As a result, conversations sound clearer, noises fade more quickly and the room becomes noticeably quieter and more pleasant.

Improve room acoustics in a targeted and suitable way
Suitable solutions for every room
From a small home office to an open-plan office: Find sound absorbers to suit the room size, use and acoustic situation.
Flexible mounting on walls and ceilings
Whether bonded, suspended or magnetically attached: Different mounting systems make it easy to integrate the absorbers into existing and newly planned rooms.
Combine acoustics and interior design
Different shapes, sizes, colours and surfaces make it possible to create solutions that blend in harmoniously or add deliberate design accents.
Personal consultation and planning
Are you unsure how many sound absorbers you need or where they should be installed? Our experts will support you with selection and planning.
Less reverberation, more pleasant room acoustics
-
Effectively reduce reverberation
Large windows, smooth walls and hard floors reflect some of the sound that reaches them back into the room. As a result, sounds linger for longer and overlap, quickly making the room feel loud and restless. aixFOAM sound absorbers absorb part of the incident sound and prevent it from being reflected back into the room by hard wall and ceiling surfaces. This reduces the reverberation time and allows sounds to fade more quickly.
-
Improve speech intelligibility and reduce acoustic disturbance
Less reverberation means that voices and other sounds overlap less. This makes conversations easier in the office, improves speech intelligibility in the classroom and makes conversations in a restaurant more pleasant. It also creates a quieter and clearer acoustic environment at home.

Sound absorbers for walls, ceilings and floors
Wall absorbers and acoustic panels make use of available wall surfaces, while ceiling absorbers and acoustic ceiling panels provide additional absorption area above the room. Freestanding sound absorbers can be positioned flexibly on the floor and are particularly suitable when wall and ceiling surfaces can only be used to a limited extent.
How many sound absorbers do I need?
For light reverberation or noise in the room, it is usually sufficient to cover ~10% of the wall/ceiling surfaces with sound absorbers. For increased reverberation, we recommend around 20%, and for strong reverberation up to 30%. If you are unsure, start with a smaller number of absorbers and add more as needed.
Improve room acoustics with suitable sound absorbers
Different acoustic solutions are suitable depending on the furnishings and available surfaces. Wall and ceiling absorbers, freestanding acoustic elements or sound absorbers for doors can be used specifically where they provide useful absorption area in the room.
Wall absorbers
Acoustic panels use available wall surfaces for sound absorption and can also be deliberately integrated into the interior design.
Ceiling absorbers
Ceiling absorbers provide additional absorption area without taking up valuable wall space in the room. Depending on the application, they can be mounted directly or suspended as acoustic ceiling panels.
Acoustic partitions and room dividers
Freestanding acoustic absorbers provide flexible absorption area and can also be used to divide and structure the room.
Door insulation sets
Our door insulation sets use existing door surfaces for sound absorption and help reduce reverberation and improve room acoustics – without taking up additional wall or floor space.

Frequently asked questions about improving room acoustics
The right acoustic solution depends on the room, how it is used and the existing surfaces. aixFOAM helps assess the acoustic problem and select the right type, quantity and positioning of suitable sound absorbers.
-
Poor room acoustics are often noticeable through long reverberation, unclear speech and an unsettled sound environment. Conversations become tiring, voices and other sounds overlap, and the room seems louder than the actual sound sources would suggest. These problems occur particularly often in large or sparsely furnished rooms with hard floors, smooth walls, high ceilings and large window areas.
-
To improve room acoustics, reflected sound within the room needs to be reduced. Sound absorbers on walls and ceilings absorb part of the incident sound before it is reflected by hard surfaces. This shortens the reverberation time, makes speech easier to understand and allows noises to fade more quickly. The key factors are sufficient absorption area and sensible distribution throughout the room.
-
When planning room acoustics, the room size, ceiling height, use, furnishings and existing surfaces must be taken into account. The position of sound sources, workstations, seating areas or listening positions also influences the selection and arrangement of sound absorbers. An office, classroom or restaurant therefore requires different planning from a living room, home cinema or recording studio.
-
The required absorption area depends on the room dimensions and the amount of reverberation. As an initial guide, for light reverberation, around 10 percent of the wall and ceiling area may be sufficient. For moderate reverberation, approximately 20 percent, and for strong reverberation, around 30 percent is recommended. With the aixFOAM quantity calculator you can obtain an initial recommendation based on the length, width and height of the room.
-
Sound absorbers should be installed where a large amount of sound hits hard wall or ceiling surfaces. It is important to distribute them effectively throughout the room; concentrating the absorption area in just one location is not always the most effective solution. Suitable positions depend, among other things, on sound sources, listening and working positions as well as relevant reflection surfaces. Wall and ceiling absorbers can be used individually or in combination.
The aixFOAM positioning guide shows various methods for identifying suitable positions within the room.
-
The right acoustic solution depends on how the room is used. In offices and meeting rooms as well as in classrooms, speech intelligibility and a quieter working or learning environment are the main priorities. In restaurants, conversations should remain pleasant even when there are many guests. In living spaces, the aim is usually to reduce acoustic disturbance, while in a home cinema or recording studio, controlled and balanced sound reproduction is important.
-
Yes, room acoustics can also be improved in rooms that are already furnished and in use. Depending on the available surfaces, wall absorbers, ceiling absorbers and acoustic ceiling panels, freestanding acoustic elements or door insulation sets can be added later. In many cases, extensive structural alterations to the room are not necessary.
-
Professional consultation is particularly useful for large, high-ceilinged or unusually shaped rooms, as well as for demanding applications. If the required absorption area, suitable positions or structural limitations are unclear, individual planning can also help avoid unsuitable purchases and an ineffective distribution. The aixFOAM acoustic experts provide support in selecting a suitable solution based on the room dimensions, its use and the available surfaces.
-
Room acoustics focuses on reducing reflections and reverberation within a room. Sound insulation, on the other hand, aims to reduce the transmission of noise through walls, ceilings, doors or other structural components between rooms. Sound absorbers improve the acoustics within the room but do not replace structural sound insulation. Depending on the noise problem, both measures may be necessary.
