In order to meet acoustical regulations and
recommendations, the three basic acoustical
criteria that are usually used are:
• sound absorption within a space
• sound insulation between spaces
• reverberation time
Generally, the recommended values apply to

office equipment switched on, but with the full
heating and ventilation services equipment of
the building functioning.
The optimum acoustic climate of a room will
have a sufficiently calm environment without
turning it into a lifeless space without identity
