Room acoustics is a field of building engineering activity that relates in particular to the comfort of speaking and listening for spaces in which they must be favored, but also, in general, to the habitability of premises, since they are likely to be occupied.

Thus, room acoustics is intended to allow obtaining, for different buildings whose construction, when it is successful, is the reputation of their builders, specific performance, in line with very strong technical requirements such as those required for operas, theaters, cinemas, concert halls.

For such constructions, many performance indicators are used e.g. clarity at 50 or 80 ms (C50, C80), early decay time EDT (Early Decay Time), speech transmission index STI, central time TS, definition D50, sound force G, lateral efficiency (LF and LFC).

ITS has the means for calculating these room acoustics performance indicators.

In addition, room acoustics aim to offer comfort conditions (according to the ambition of the parties involved in the project, often modulated according to the existence or the absence of regulatory obligation: acceptable, or sometimes: the best possible), for living places as varied as station or airport halls, meeting rooms, premises of educational institutions (e.g. rooms for teaching or practical activities, administration, library, information and documentation center, music room, meeting room, teacher's room, medical room and infirmary, multipurpose room, dining room), sports halls (e.g. gymnastics, athletics, volleyball , handball, basketball, tennis, fencing, table tennis), health establishments (e.g. restaurants, staff rest rooms, public reception areas, accommodation or treatment rooms, examination rooms or consultation, medical or care offices, premises and circulation accessible for public), or institutions for children under 6 years (atrium, playrooms - and activity rooms – for the different sections, sleeping rooms, offices, medical premises , rooms reserved for staff, halls and stairwells likely to be used regularly by children).

For such premises, the reverberation time (duration) is often a fundamental indicator of their acoustic quality.

ITS has the means for the calculation of this indicator for room acoustics performance as well as means for its on-site measurement (e.g. before works to carry out a diagnosis, or after works, to check the effectiveness of arrangements made in terms of soundproofing) .

It is also the case for other living places that are the restaurants, the bars, the places with diffusion of amplified music, as well as the offices and associated spaces (individual or collective offices, open spaces, empty levels, meeting rooms / training rooms, relaxation areas, aisles).

In the case of work premises, the noise level decay per doubling of distance from a source is the current performance indicator: ITS also has the means for simulating this indicator of room acoustics performance as well as the means for its measurement on site.

In terms of room acoustics, the ITS service offer includes on-site measurements, comparison of measurement results with reference values (e.g. regulatory or normative), and improvement proposals (description of recommended actions), sizing and marketing of solutions (soundproofing equipment), with or without installation.
