Industry Information

Soundproofing is the process of reducing unwanted noise and noise pollution, and in preventing noise from entering or leaving specific areas. Soundproofing materials and products absorb the excess sound in rooms, chambers and around pieces of equipment in order to create quieter environments for the purposes of worker safety, product testing, audio mixing and research etc.

To avoid damage to employees, products and equipment, facilities where excessive equipment noise is a concern use soundproofing products such as acoustic flooring to absorb floor vibrations or acoustic curtains to surround equipment, absorbing their sound. Acoustical ceilings, acoustic baffles, acoustic foam and acoustic panels are also common elements of sound proofing systems as they provide large surface areas of sound wave absorbent materials to reduce the reverberations within a space. Noise reduction and sound insulation have become important elements of construction and building layout as unwanted noise can not only be physically harmful and painful, resulting in hearing loss, stress and sleep loss; it can also decrease concentration, productivity, and peace of mind. Noise pollution from heavy traffic is a major concern in some areas, and sound barriers are often erected as a response. Some specialized applications such as recording studios, acoustical research centers or equipment testing procedures require customized soundproofing solutions, and anechoic chambers, which provide essentially dead space, are one example of this.

Noise can be either airborne through the air including voices and music and traffic sounds, or it can be structural or impact noise caused by machinery vibrations, footsteps or the sounds of building systems such as plumbing or heating which pass through the floors and walls. These sounds can prove a disrupting and unpleasant environment in which to live or work. Furthermore, excessive equipment noise not only causes distractions and poor communication in the workplace, but in heavy manufacturing settings, it may cause permanent audio damage to workers as well. Even though noise only stays in the air for a short time, its effects are cumulative in terms of temporary or permanent hearing loss and therefore soundproofing is a worthwhile investment for many applications. Soundproofing materials work by absorbing sound, dampening vibrations, or as sound barriers; or as a combination of the three processes. Sound absorption is achieved with the use of soft, porous, open-celled foams such as polyurethane foam, which trap sound waves within the foam's labyrinth of non-reflective cells. The higher the ratio of sound barrier surface area to open space, the greater the sound absorption; for this reason, anechoic chamber manufacturers line walls, ceilings and even floors with corrugated foam wedges or panels with pyramid or egg-crate shaped surfaces, which absorb far more sound than flat foam or other acoustic panels. Product testing rooms and acoustical research centers requiring absolutely minimal noise pollution build anechoic chambers, or noise control rooms, lined completely with acoustic foam panels, acoustic drywall and acoustical ceilings. These rooms absorb almost all the sound waves produced by a piece of equipment or machinery.

Depending on the desired results, noise reduction installation may be as simple as installing several acoustic panels or acoustic baffles on the surface of a wall, or it may be as complex as building an entire soundproof anechoic chamber. Medical hearing facilities and product testing facilities, such as computer testing chambers, require soundproof chambers to measure decibel levels given off and affected by products. Other common uses of sound proofing materials include in sound mixing studios, performance halls and theaters which use acoustic foam as sound insulation on acoustic wall panels and acoustical ceilings in order to prevent noise pollution or echoes which distort and dilute the main audio. While wall panels and sound insulation absorb airborne sound waves, acoustic flooring and vibration dampening materials reduce the amount of vibration energy transmitted between surfaces constructed of rigid materials, which typically transmit vibrations at multiple frequencies. Acoustic flooring is also important in other types of industries for reducing noise pollution caused by walking or operating equipment on a cavernous floor. Carpet and fibrous materials provide a significant level of floor soundproofing for some applications, although tiled or uncarpeted floors may be effectively soundproofed by other means. Acoustic flooring contains insulation and vibration shock absorbing materials layered on top with thin layers of acoustic foam and porous mineral boards.

Soundproofing is not only required for testing chambers, studios and noisy facilities, but also for smaller equipment such as computers or domestic appliances, and for consumer machines such as cars or jet skis. Mufflers, grommets, shocks and vibration isolators are examples of soundproofing applied locally to equipment. Computers contain soundproofing materials, and computer workstations in offices are often housed in soundproof or semi-soundproof rooms. Sound isolation rooms, also known as audiometric booths, are available to audiologists, doctors, hearing aid specialists and hearing clinics for hearing testing and to gather more research on the way in which sound travels and works. Federal government regulations stipulate maximum noise levels in work environments, schools, offices, airports and other public buildings, often requiring these facilities to install a certain amount of soundproofing in order to remain functional and safe.

Soundproofing Types

  • Acoustic baffles are constructed of one or two cores of dimensionally stable medium density glass fiber and suspended vertically from a ceiling structure. Acoustical baffles are designed for areas where standard acoustical ceilings are not feasible or as an additional acoustical treatment in existing spaces.
  • Acoustical blankets consist of polyvinylchloride outer shells and acoustical batting. Acoustical blankets can be hung from vertical uprights or attached to a frame, enclosing a piece of equipment to absorb and stop noise.
  • Acoustical ceilings consist of a suspended ceiling grid and high sound absorption lay-in acoustical panels or tiles and provide a lightweight and attractive ceiling system. Acoustical ceilings, which are quickly installed, can be used to control the quality of sound effectively in a specific space.
  • Acoustic curtains are heavy duty drapes or linen panels made of specially designed materials that prevent noise from moving between spaces.
  • Acoustical enclosures are used when sound must be prevented from spreading from one area to another. Acoustical enclosures include recording booths, industrial enclosures of all kinds, highway walls and noise barrier walls.
  • Acoustic foams are used to line sound-reflective surfaces. They reduce noise by allowing the sound energy to penetrate into the material and be dissipated by its cellular or fibrous nature prior to reaching the reflective surface.
  • Acoustic flooring are layers of sound-absorbent material underneath flooring material that reduces sound heard between floors in multi-level buildings.
  • Acoustic panels are fastened to walls in order to absorb unwanted noise.
  • Barriers provide a high density layer used to separate or prevent noise from entering a certain area or leaving a contained area. Common uses for barriers are bulkheads, firewall treatments, cab floors and pipe wraps.
  • Clouds are panels similar to acoustical baffles but are hung in a horizontal position from the ceiling or roof structure.
  • Damping materials aid in the control of vibration and structure borne noise often through friction or time. This method is common with sheet metal panels, cab enclosure panels, boat hulls and deck plates and HVAC ductwork.
  • Diffusers scatter a sound wave from a surface. Sound direction is changed so listeners may experience sound coming from different directions at equal levels.
  • Intake silencers decrease the noise and destructive low frequency pulsations at blower inlets.
  • Isolators can reduce vibration by having greater attenuation in one direction than the other and are often found installed under some defined load factor between two surfaces, such as generator pads.
  • Modular acoustical panels are easy-to-use portable panel products, such as partitions, wall-mounted panels, baffles and privacy screens.
  • Noise pollution refers to any unwanted and unpleasant sound.
  • Noise reduction strives to diminish the amount of noise pollution in a given area by breaking, blocking, absorbing or isolating unwanted infiltrating sound waves.
  • Reflectors are used to regulate the amount of sound that is reflected off a surface. Reflectors are often used in acoustically sensitive settings.
  • Silencers reduce the level of sound through either absorptive, reactive or a combination of mechanisms.
  • Sound absorbers are noise control materials and are directly related to the amount of surface area available to be treated. Sound absorbers are frequently found in machine enclosures, housings, industrial environments and medical, marine and transportation applications.
  • Sound barriers use a walls of high density material to reduce roadway noise.
  • Sound insulation or acoustic insulation absorbs the frequencies transmitted by sound waves and prevents unwanted noise and vibration.
  • Sound proofing refers to the methods used to reduce the intensity of sound.
  • Soundproofing materials are used to control or reduce the amount of noise in a given environment by blocking the sound from entering or leaving the space.
