Soundproofing of a hall for amplified music: dance club

Soundproofing a hall for amplified music (such as a discotheque or dancing club, a concert hall, an auditorium) is not only necessary (for the envelope of the building which must oppose sufficiently the transmissions noise), which is based on the respect of an emergence limit value i.e. the difference between the A-weighted equivalent continuous pressure levels of the ambient noise (hall for amplified music in operation) and residual noise (in the absence of the noise generated by the hall for...

Silencer for superheated steam circuit

A silencer for superheated steam circuit is necessary when its downstream part opens into the atmosphere, because the expansion of the pressurized fluid is then accompanied by noise emissions characterized by an acoustic power whose level currently reaches or exceeds 150 dB (A), which would be of a nature (if nothing was done) to cause severe auditory trauma to workers operating nearby and a serious disturbance to the neighborhood.

ITS will participate in the construction of a silencer for a...

Noise control of an electric power plant

Noise control of an electric power plant causes facing technical issues of all kinds.

Acoustics have, of course, a place of choice, since acoustic powers are involved whose overall levels exceed 135 dB (A) for many equipment constituting such installations, in a context where sound levels below 80 dB (A) at 1 m are often required (for the protection of site personnel), however, sound levels as low as 60 dB (A) or even 50 dB (A) are imposed at the limit of industrial property: the health of the...
