Acoustic absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body. The energy transformed into heat is said to have been ‘lost’. Acoustic absorption is of particular interest in soundproofing. Soundproofing aims to absorb as much sound energy (often in particular frequencies).
An anechoic chamber (“anechoic” meaning non-reflective, non-echoing or echo-free) is a room designed to completely absorb reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise.
Semi-Anechoic Room where sound reflections only come from the floor. The walls and ceiling are absorbent making it ideal for acoustic testing.The solid floor makes this room much easier to work in than the anechoic chamber.
The walls are perforated panel to be used for sound absorption. Installed in the room to reduce wall resonance. Have sound absorption properties in the wide frequency range. Easy installation and strength.
Acoustic enclosures from SP SONIC reduce noise pollution from noisy plant and machinery without reducing the efficiency or cleanliness of the plant during normal operations.
Fabric Noise Absorption Panel Also make a great alternative to fabric stretch wall systems. These Fabric Acoustic Absorption Panels look as good as they sound.
Noise barrier is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources – other than cessation of the source activity or use of source controls.
High volume fans and air handling units are used in large commercial, institutional and industrial buildings to provide treated air to the occupants and to remove exhaust air and fumes from the buildings. This can result in duct noise levels which exceed established standards and regulations.
