Acoustic comfort is an environmental key factor for all living areas that must have minimal performance so as not to be unsuitable for their destination, in particular with regard to the problem of reverberation limitation and also with regard to the issue of isolation to airborne noise.

In nurseries, day-care centers, kindergartens: to atrium, activity and play rooms, sleeping rooms must be paid a special attention in terms of acoustics, as to offices, medical rooms, rooms reserved for staff and also halls and stairwells.

In France, the recognition of acoustic comfort as an environmental key factor in buildings is not yet translated into a regulation (in the form of orders or decrees) that all the aforementioned premises should meet, but the appropriate values ​​of the indicators of acoustic performance of interest are the subject of a fairly broad consensus.

In educational establishments, whether nursery schools or not, rest and exercise rooms, teaching premises, activity and play areas, reception halls and closed assembly rooms shall be soundproofed, as teachers' rooms, medical rooms (e.g. infirmaries), meeting rooms, washrooms, dining rooms, kitchens, and also circulations and cloakrooms; where they exist, music rooms, multipurpose rooms, sports halls or noisy workshops must be soundproofed as well.

In health facilities, acoustic performance indicators must meet minimum values ​​for accommodation and care spaces, examination and consultation rooms, medical and nursing offices, waiting rooms, operation, obstetrics rooms and bithing rooms, as well as in the internal circulations, and other premises where patients may be present.

In hotels, rooms and bathrooms, indoor circulations must have high-performance sound insulation, and also offices, staff rest areas, cloakrooms, reception halls, reading rooms, meeting rooms, bars, kitchens, and even: workshops, shops, garages, car parks, delivery areas, toilets, TV rooms, laundries, garbage rooms; when hotels are equipped with them: gymnasiums, swimming pools, restaurants, casinos, reception rooms, discotheques and dance halls must comply with the regulations in force in relation to noise limitation.

In residential buildings, the main rooms, kitchens and bathrooms must be sufficiently efficient in terms of airborne noise insulation with respect to other dwellings, common indoor circulation building, garages (individual or collective) and business premises.

Acoustic comfort – an environmental
key factor in buildings
   

Work rooms where machines and appliances are likely to expose workers to a daily sound exposure level exceeding 85 dB(A) shall have minimum characteristics so as to limit the amplification of sound levels in relation to reverberation.

In France, recognition of acoustic comfort as an environmental key factor in buildings is reflected in regulations (in the form of orders and decrees) to which all the above-mentioned premises are subject.

In addition, in the offices and associated areas (individual or collective offices, open spaces, meeting rooms, relaxation areas, restaurants, circulations, and even: floors to be set up) acoustic comfort as an essential environment factor can be properly accouted if an ad hoc standard, despite not mandatory, is considered.

Moreover, insulation of air noise between premises, insulation from the noise of the outdoor space, shock noise level, reverberation time, noise level from equipment for sports halls (i.e. reserved for the practice of following sports: gymnastics, athletics, volleyball, handball, basketball, tennis, fencing and table tennis) are specified in another ad hoc standard which is also not mandatory.

Acoustic comfort is an environmental key factor in buildings for which ITS offers its services (measurements, study, advice, sizing).
