acoustic absorption

Often acoustic absorption of materials is given in decibels instead.

Acoustic absorption is of particular interest in soundproofing.

Acoustic absorption is critical in areas such as:

It has virtually no permanent acoustic absorption, relying on room shape and deflective elements to achieve control of reverberation.

Martin Richman designed and created 270 fabric-covered acoustic absorption panels, which were dyed and painted.

Because acoustic absorption and the absorption of light depend on different principles, there is no need to boost artificially visual contrast by staining.

It is therefore recommended that at least 60% or more of the reflective surfaces inside this type of isolation booth be treated with acoustic absorption products.

The choice of sound absorbing material will be determined by the frequency distribution of noise to be absorbed and the acoustic absorption profile required.

Some acoustic energy is lost every time an echo is formed, but most of it (approximately ) is lost from acoustic absorption.

Acoustic absorption refers to a material, structure or object absorbing sound energy when sound waves collide with it, as opposed to reflecting the energy.

Spaces which are highly non-diffuse are ones where the acoustic absorption is unevenly distributed around the space, or where two different acoustic volumes are coupled.

Sound reflections: by limiting the reflection using many methods, e.g. by using acoustic absorption (deadening) materials, trapping the sound, opening a "window" to let sound out, etc.

This system gives a large acoustic absorption at low frequencies (under 500 Hz) and reduces at high frequencies to compensate for the typical absorption by people, lateral surfaces, ceilings, etc.

The ship felt mushy, foamy, the rubbery tiles of the acoustic absorption material making the surface less able to reflect the sound waves of an active sonar pulse from a surface ship.

Therefore it is usually recommended that some type of acoustic absorption product, such as acoustic foam, heavy curtains, acoustic panels, or absorption baffles be used on a significant percentage of the screen surface and opposite the screen in order to soak up and dissipate as much of the direct and reflected sound energy as possible.

It attempts however to normalize the measured difference level to the level which would be present when the rooms are furnished by measuring the quantity of acoustic absorption in the receiving room and correcting the difference level to the level which would be expected if there was 10m Sabine absorption in the receiving room.
