General information about room acoustics

What areas of application are there for sound absorbers?

Sound absorbers are used to optimize room acoustics in various environments, including offices, conference rooms, gaming rooms, home studios, rehearsal rooms, public spaces and private households. By minimizing disruptive echo effects, they improve speech intelligibility and create a more pleasant acoustic environment.

How do sound absorbers work?

Sound absorbers improve room acoustics by absorbing sound waves and converting them into heat. This prevents reflections and reduces reverberation in the room.

Can sound absorbers reduce outside or neighborhood noise?

Sound absorbers are primarily designed to optimize room acoustics and minimize reverberation. They absorb sound, minimize echo and reverberation in the room and thus help reduce noise. However, they cannot significantly reduce noise that is transmitted from room to room or from outside.

How many sound absorbers do I need for my room?

The amount of sound absorbers required varies depending on the size of the room and acoustic requirements. As a rule of thumb: For slight reverberation, around 10% of the empty wall surface should be provided with sound absorbers, for increased reverberation around 20% and for strong reverberation around 30%.

Where should sound absorbers be placed?

Sound absorbers should ideally be positioned opposite the sound source to achieve the greatest effect. They should be placed so that they absorb the so-called initial reflections.
