Soundproofing is often used to control the amount of noise in an environment. In order to do this, multiple methods can be used such as absorbing sound, dampening vibrations, or sounds barriers.
Noise absorption materials suppress echoes, reflections, resonance, and reverberations whereas noise reducing materials lessen the energy of the sound waves. Before implementing soundproofing materials, it is important to research the best solution for each application. Some components are used in conjunction with each other and others may be used if the space allows. A variety of industries utilize soundproofing materials such as industrial, commercial, and even residential to make places acoustically pleasant. Common places include recording studios, edit rooms, research facilities, function halls, gyms, and even upgraded laundry rooms. To block noise for industrial workers, acoustic curtains are often used when need be.
Soundproofing involves using materials that are able to trap noise and prevent reverberations that would send noise pollution back into the space. Materials that are corrugated, uneven, or jagged in appearance are the most effective because they increase the ratio of the sound barrier and opening space. They allow the sound waves to dissipate more fully and absorb noise. Examples of this can be foam, wedges, rock wool, sheetrock, high mass vinyl, fiberglass, rubber, aluminum, composite, glass, polyethylene, mineral wool, and soundboard. Mineral wool fibers are good example of soundproofing options that are non-combustible and have high melting points allowing them to be used around heat generating industrial machines without serious risks. These materials can be applied during or after construction of a space, however post-construction soundproofing is often far less effective than installing a sound-proofing material from the beginning.
