Ceilings, islands and acoustic panels - advantages for use in public buildings

There are many advantages of using acoustic materials in commercial interiors and they are strongly related to the character of such objects. Sound absorbers reduce reverberation time, make speech clearer and reduce reverberation noise in the interior.

Industrial acoustics

Consider which rooms require good speech intelligibility. Taking into account the PN-B-02151-4 standards, these will be: classrooms and studios, lecture halls in primary, secondary and higher schools, auditoriums, as well as courtrooms, auditoriums, and others of this type. It is worth mentioning that the requirements related to speech intelligibility are sometimes superior to the reverberation time criterion. According to the design practice, it can of course be stated that the following facilities can also be added to the group of the above mentioned rooms: sports halls in schools and sports centres, as well as railway stations and churches.

Coupling in acoustics

Reverberation noise is first of all a source of errors in the communication path, it also causes faster fatigue, increased deconcentration, as well as hinders learning or work. It is also extremely unfavourable in the case of convalescence of patients in hospital buildings. It is worth noting that the noise is intensified - noisy rooms make the loud behaviour intensify, which has a negative impact on the course of classes or the concentration and efficiency of employees. Adequate acoustics in classrooms and offices undoubtedly helps to eliminate such problems. Reducing reverberation noise in educational or, above all, sports halls, causes a gradual indirect improvement in the condition of hearing aids and voices in teachers. This is because they are forced to strain vocal cords frequently, and sometimes they must stop the process of illness or make it shift in time.

Reducing reverberant noise will make them feel better and increase the comfort of their work. In the case of places that are intended for rest, regeneration or convalescence, it will have a beneficial effect on the regeneration of students, hospital patients and office workers.
The rooms where silence is absolutely necessary are, of course, libraries, reading rooms, churches, media centres and exhibition halls in museums. Unfortunately, they are usually designed in such a way that despite the appropriate efforts of the users (i.e. observing the required silence), it is not possible to obtain the recommended sound levels.
