TEMPO products’ acoustic absorption

For optimal acoustic comfort

Accueil > News > Sound absorption of TEMPO Products

TEMPO’s products are acoustic absorption products. They reduce reverberation time (RT) in spaces. RT is the time required for a sound to “fade away” or decrease by 60 dB after the sound source has stopped. It’s expressed in seconds and is used for characterizing a space using the following terms: reverberant, semi-reverberant and mute. The more absorbent materials a space has, the shorter the reverberation time.

Key concepts in acoustic absorption

Sound

Sound, characterized by its level that defines its amplitude, is expressed in decibels (dB) and is given a Lp rating (sound pressure level rating) in standards and regulations.

Sound is also characterized by its frequency, expressed in Hertz (Hz). This corresponds to the number of vibrations per second. It distinguishes between low-pitched and high-pitched sounds.

Insulation and Absorption

Insulation corresponds to any process rolled out to reduce the sound level, not in the space where it’s emitted, but in the adjoining space.

TEMPO products don’t deal with acoustic insulation (airborne or structure-borne noise) but with acoustic comfort. We seek to reduce the part of the sound wave that’s transmitted through a surface (wall, ceiling, ground).

Reverberation

In a space that has no acoustic absorbent on its surfaces, the paths and durations of direct sound waves and those reflected off the surfaces are very different.
A listener receives direct sound waves and reflected waves with a time lag.
The greater this time lag (i.e. the more reverberant a space is), the more the feeling of hubbub will be felt and the more the comprehensibility of speech will be impaired.
