What Do I Need
This process explains how acoustic panels absorbs excess sound (noise) in a space.
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 two most commonly-used sound absorption materials are high-quality acoustic foam and specialized acoustic fiberglass (no, not the stuff you buy at the hardware store). For brevity, at times we’ll generically call acoustic foam just plain “foam,” although there are very dramatic differences in cell structure and density between acoustic foam and the thousands of other types we could manufacture. (This is why you can’t just run down to the local SuperMart and buy mattress pads with which to acoustically treat your studio.)
While Absorption is an important piece of acoustical treatment, make sure to complete your room plan by also including our Bass Trapping, Diffusion, and ISO-Series products in order to maximize the effectiveness of your total treatment system. Additionally, our Construction/Isolation products can be used for sound isolation of a space.The energy transformed into heat is said to have been ‘lost’.
When sound from a loudspeaker collides with the walls of a room part of the sound’s energy is reflected, part is transmitted, and part is absorbed into the walls. Just as the acoustic energy was transmitted through the air as pressure differentials (or deformations), the acoustic energy travels through the material which makes up the wall in the same manner. Deformation causes mechanical losses via conversion of part of the sound energy into heat, resulting in acoustic attenuation, mostly due to the wall’s viscosity. Similar attenuation mechanisms apply for the air and any other medium through which sound travels.
The fraction of sound absorbed is governed by the acoustic impedance of both media and is a function of frequency and the incident angle.Size and shape can influence the sound wave’s behavior if they interact with its wavelength, giving rise to wave phenomena such as standing waves and diffraction.
Acoustic absorption is of particular interest in soundproofing. Soundproofing aims to absorb as much sound energy (often in particular frequencies) as possible converting it into heat or transmitting it away from a certain location.
In general, soft, pliable, or porous materials (like treated acoustic panels) serve as good acoustic insulators – absorbing most sound.
