WebReverberation (also known as reverb), in acoustics, is a persistence of sound after it is produced. Reverberation is created when a sound or signal is reflected. This causes numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most …

Sabin (unit) - Wikipedia

The sabin (or more precisely the square foot sabin) is a unit of sound absorption, used for expressing the total effective absorption for the interior of a room. Sound absorption can be expressed in terms of the percentage of energy absorbed compared with the percentage reflected. It can also be expressed as a coefficient, with a value of 1.00 representing a material which absorbs 100% o… WebSabins refers to the total amount of absorption within a space. Most noteworthy, in order to calculate Sabins, a consideration for the surface area and absorption must take place for every material within a space. To obtain the sabin values, we use the volume (length x width x height) of the room as well as the surfaces materials. proprietary cartilage blend 中文http://scihi.org/wallace-sabine-architectural-acoustics/ requirements in agile methodology
