Acoustics_Vocabulary



Is the term for the study of sound and how sound is experienced. The field of acoustics is divided into several specialist areas.
 * Acoustics **

A classification of suspended ceilings according to their ability to contribute to the acoustic privacy between work stations. . The Articulation Class (AC) can be calculated from the interzone attenuation. This can then be used as a tool to classify and compare acoustic ceiling systems. A high Articulation Class gives some privacy, a lower Articulation Class means lower privacy. Confidential conversation and work tasks demanding concentration need good privacy. || AC Occurs when noise bounces between parallel surfaces in a room.

<span style="font-family: Verdana,Geneva,sans-serif; font-size: 130%;">The time it takes for the sound pressure level to fall by 60 dB after the sound has been turned off. Measuring the reverberation time allows us to calculate the total sound absorption. The reverberation time varies according to the frequency.

<span style="font-family: Verdana,Geneva,sans-serif; font-size: 130%;">The ability of a building element or building structure to reduce the sound transmission through it.
