A close-up image of acoustic foam. Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airborne sound waves, reducing their amplitude, for the purposes of noise reduction or noise control. [1] The energy is dissipated as heat. [2] Acoustic foam can be made in several different colors, sizes and thickness. [3]
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.
A "Mr. Clean Magic Eraser" brand sponge, made from melamine foamMelamine foam is a foam-like material consisting of a melamine-formaldehyde condensate.It is the active component of a number of abrasive cleaner sponges, notably the Magic Eraser.
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
Due to the closed-cell nature of rigid polyurethane foams, PUR insulation has minimal water absorption, which coupled with an appropriate cover, makes it a particularly suitable in applications where bacterial growth is a concern. Polyurethane insulation is suitable for insulating pipes with surface temperatures ranging from -196°C to 148°C. [7]
Resonating bass traps will absorb sound with high efficiency at their fundamental frequency of resonance. As such, a knowledge of the frequencies of resonances which require damping is helpful before designing and constructing a resonating bass trap. This can be attained by calculation of the room's modes or by direct measurement of the room ...
Using a combination of sound absorption materials, arrays of microphones and speakers, and a digital processor, a restaurant operator can use a tablet computer to selectively control noise levels at different places in the restaurant: the microphone arrays pick up sound and send it to the digital processor, which controls the speakers to output ...
