Indoor noise may most commonly be thought of at home or the office, but how about other areas at the workplace? A production floor, a warehouse, a storage room, anyplace machinery is under roof and so on. At Sonic-Shield, we use both sound barrier and sound absorption materials to dampen or completely deaden indoor noise from a variety of sources in the home and office BUT, we also use sound dampening enclosures, acoustic panels, curtains, baffles, blankets and a wide variety of other solutions to address your specific indoor noise problem.
Below, you will find a short list of the most common types of indoor noise that you are likely to encounter, and how we generally address indoor noise problems.
- Sound transmission through walls – We use combinations of sound barrier and sound absorption materials, combined with customized construction techniques, specific to your indoor noise problems to reduce the sound transmission through exterior or interior walls. Our Sonic-Shield acoustic barrier materials, when added to a typical wall, can increase the STC of the wall from 33 to over 53, reducing the perceived loudness of the transmitted noise by 75%!
- Sound transmission through floors and ceilings – Walking on hard surfaces, such as tile or wooden floors creates indoor noise that can easily pass through floors and disturb occupants below, in a multi-story home or office. We use combinations of sound absorbing under layment on floors and sound barrier and sound deadening materials on ceilings to reduce the transmission of sound through floors.
- Sound transmission through windows – Windows can transmit the largest amount of noise into homes and offices. Various solutions can be employed to reduce this indoor noise, including the use of acoustic windows, sound dampening treatments in the window mullions, and acoustic caulking or acoustic films applied directly on the window, which dampens indoor noise without having to replace the windows.
- Airborne noise from industrial machinery that passes through openings, apertures and other structural gaps can be treated by “plugging the gaps” with sound insulation or sound absorption materials.
- Acoustic reverberation within rooms -Highly reverberant rooms adversely affect the quality of sound within the room, negatively impacting our ability to hear speech or audio equipment, resulting in a “muddy” sound. Again, we use customized sound deadening materials, some of which can be covered in decorative fabrics that can be installed on walls or ceilings within rooms.
- Heating, Ventilation and Air Conditioner noise – Indoor noise from fans in HVAC systems travel through the ducts and return vents, and may affect every room in the house or office. We have developed effective duct and fan silencers that are capable of reducing indoor noise by 15-20 dB, a reduction of perceived loudness by 67-75%. In some cases, we will prescribe the use of acoustical plenums or acoustical wraps on the ducts to eliminate resonance or noise from duct panel vibration, as vibrations generally mean more noise!
- Structural borne sound, created by impact or vibration can be treated either at the source by building an enclosure or at the “receiving end” by creating a barrier for the noise, or decoupling the “receiver” from the vibration causing the indoor noise.
- Outdoor air conditioner (AC) evaporators – Noise from outdoor AC evaporators can often be heard by homeowners within the house or on outdoor patios. We have developed a modular sound deadening panel system, containing both sound barrier and sound absorption materials, which are capable of reducing the direct transmission of noise to the environment and minimize acoustical reflections off of nearby walls and structures.
Sonic-Shield offers a full range of soundproofing products and develops customized soundproofing solutions to solve even the most demanding indoor noise problems. Our team of acoustic experts can help you pinpoint sources of noise and rapidly develop cost effective solutions to; eliminate, block or absorb the noise.
Sonic-Shield believes that while there may be similarities, no two indoor noise pollution problems are exactly alike. Accordingly, our soundproofing solutions reflect our ability to identify, and when necessary, develop and fabricate the appropriate soundproofing materials for your particular needs.
Whether you have a problem requiring an immediate solution or have the luxury of planning for a problem that will exist in the future, inside or outside, we would like to discuss your indoor noise or vibration problem with you.
