What is Reverberation?

One of the key aspects of acoustics within a room is reverberation. Reverberation is the outcome of sound being reflected by a surface in which a large number of reflections join up and eventually absorbs into the objects in the encompassing environment, such as furniture or people. The most commonly known example of the reverberation is an echo which is caused by the reflected sound waves to pass at different times, causing a delay in speech. Echos can be heard when the delay of the sound is 100ms from the source.

What is Soundproofing and the effects?

Soundproofing inhibits sound from coming into a room or building from outside. This is accomplished by altering the physical structure of a building so that airborne noise and vibrations are restricted from passing through. When it comes to soundproofing, if air can pass through it, then noise can also get through it. The most common way sound waves travel is air-borne noise, which can be produced by voices or speakers. The other method would be impact noise, which for example includes footsteps or knocking.

What is Sound Diffusion?

Sound diffusion is another key component, which is the process of disseminating the number of sound waves reflecting in a certain direction, thus scattering the energy. A diffuser causes the sound to disperse evenly in random directions as a result of the different depths in the design of the system.

They are also an excellent alternative or can be used to complement a Soundis sound absorption product because they do not remove sound energy, but instead interrupts discrete echoes by scattering or dispersing sound energy over a wide area without absorbing it from the room, while still improving speech intelligibility and maintaining sound clarity.

What is Sound Absorption?

Unlike sound diffusion, sound absorption is the process of removing sound energy from an environment, while diffusers reflect sound waves in different directions. Depending on the class of absorption, a highly absorbent material will only reflect a small proportion of the sound energy.

Whilst absorbing the majority by turning the sound energy into heat energy when the waves hit the absorbent material. (To achieve a Class A sound absorption, the product is required to absorb over 90% of the energy) Sound Diffusion and Sound Absorption products can be used together, to achieve optimal acoustic values, as they do allow to enhance the effectiveness of the systems combined.
