Acoustic comfort is defined as a psycho-physical condition where a person, in a specific environment, experiences a sense of well-being in relation to the specific activity that he/she is doing.
Considering the complexity of Acoustics in professional spaces we will not analyze in this section the parameters related to professional audio and music spaces.
The acoustic comfort is the result of the right balance of acoustic conditions in an environment, not to be confused with the complete absence of noise.
In this regard, it is interesting to think about the acoustic condition that is created inside an anechoic chamber. The laboratory is designed to make sound absorbing measurements by creating an artificial state of absolute silence, which often causes a strong discomfort for people who access for the first hour. The explanation of this phenomenon is very simple, since the state of total silence does not exist. This is probably linked to aboriginal self-defense mechanisms that makes us feel a state of absolute silence as a sign of an imminent threat.
We all had the experience every day, for example when we are in a completely empty restaurant and silence is not necessarily associated to a real sense of acoustic well-being.
The acoustics conditions of well-being or malaise is not only determined from the level of noise in a room. It is necessary to consider the characteristics of "spectral" sound, because if it is too high or too low it could be very uncomfortable. An acoustic correction therefore aims to reduce the ambient noise by acting on the reverberation component.
