Improving the acoustic comfort of an activity room for children is a recurring problem in a nursery, especially if the construction is based exclusively on sound-reflecting materials such as concrete or glass. For then ambient sound levels are usually too high, which is causing the occupants, young and older a nuisnace whose consequences are stress and excessive fatigue. As a result, children do not have favorable conditions for learning, and supervisory staff have difficulty in performing the tasks they are required to perform in their professional activities: they all suffer from an unfavorable sound environment.
ITS can help improve the acoustic comfort of a children's activity room by marketing absorbent materials that reduce the harmful effects of excessive reverberation. The selection of these absorbing materials in terms of quality (which absorption coefficient to retain at the frequencies corresponding to the envisaged sound emissions ?) and in quantity (which surfaces to cover e.g. for the ceiling and on the walls ?) is the subject of a study based on on the measurement of an indicator of the acoustic quality of the considered space, in the state where it is when ITS has been requested: the reverbetaion time (duration), which can be subject to a result guarantee after works, illustrating the quality of the soundproofing performed.
An absorbing ceiling or suspended baffles, a wall absorbing lining are common components of any soundproofing system envisaged for the improvement of acoustic comfort of an activity room for children.
