The period of time between the silencing of a sound source, i.e. the origin of the sound waves, to the reduction of the reverberation to a defined fraction of the initial value is known as the reverberation time. In a nutshell, a reverberation time of four seconds means that the sound can still be perceived for four seconds. Depending on the room and requirements, these four seconds may feel annoying. It should be noted that the requirements for the room acoustics, i.e. relating to the reverberation time, may be very different depending on the purpose of the room. An airport hall has different requirements to a music school or a library, which is exactly where our acsono panels come into play. Thanks to our in-house planning and production of the panels, we offer tailored absorption values for the most demanding requirements.
