sabinsyksiköinä

Sabinsyksiköinä is a Finnish term that translates to "in units of sabins" when referring to acoustic measurement. The sabin is a unit of sound absorption, named after physicist Wallace Sabine. It quantifies the sound absorption of a material or surface. One sabin represents the absorption of one square foot of a perfectly absorbing surface at a frequency of 1000 Hz. In practice, materials are rated with absorption coefficients, and their total absorption in a room is calculated by multiplying the area of the material by its absorption coefficient and then summing these values for all surfaces in the room. The total absorption of a room, measured in sabins, is a crucial factor in acoustic design, influencing reverberation time and overall sound quality. A room with high total absorption will have a shorter reverberation time, meaning sound will decay more quickly, which can be desirable in environments like recording studios or lecture halls. Conversely, a room with low total absorption will have a longer reverberation time, which might be preferred in concert halls for a richer, more sustained sound. Therefore, "sabinsyksiköinä" indicates that a measurement or calculation is being expressed using this standard unit of sound absorption.
