![]() Pneumatic exhaust noise can be reduced by up to 30dB by fitting silencers. 5 Fitting Silencers to Pneumatic Exhausts In axial or centrifugal flow fans, you can increase noise control simply by changing control systems or pulley sizes and resetting dampers. It reduces room-to-room noise by up to 46dB. Meanwhile, Soundstop 5 is a multi-purpose acoustic barrier that's ideal for ceiling voids or within partition walls. Acoustic Socket and service boxes are made from two layers of 10mm-thick high-density gypsum-based board and will ensure the acoustic integrity of any metal or timber-framed separating wall containing sockets and/or services. Instead of fitting silencers, it is often possible to achieve a 10 - 20 dB reduction in airborne noise from a duct or opening by lining the last bend in the ductwork with foam or fibreglass, or constructing an absorbent, lined right-angled bend to fit on the opening. Typically used in extraction, ventilation and cooling, ductwork involves openings in walls and enclosures. 3 Preventing Noise Being Carried by Ductwork This method can also help to reduce cooler noise. One of the most effective fan noise reduction techniques what will cut down on up to 12 dB is to ensure at least 2-3 duct diameters of straight duct between any feature that may disturb the flow and the fan itself. Common sources of excess noise are bends close to the fan and dampers. 2 Running Fans EfficientlyĬuriously, when fans operate at peak efficiency, they're at their quietest. It takes screws and nails direct, and is extremely durable, yet only 17mms thick. Maxiboard soundproofing for ceilings and floors can also help meet Part E Regulations and can be used to form enclosures and independent structures. It can be used to comply with the Building Regulations Approved Document E (2003), is easy to install and is only 28mms thick. It offers high levels of airborne and impact insulation when used on timber. Maxideck, an acoustic flooring solution, can be used in kitchens and bathrooms. Maxideck and Maxiboard from Sound Reduction Systems (SRS) can help with soundproofing for floors. Or information about noise reduction in the home, please read our guides to domestic sound proofing techniques.ĭamping is typically used in applications such as chutes, hoppers, panels and tanks, damping usually uses two noise reduction techniques: layer damping, in which a layer of bitumastic damping material is stuck to a surface, and constrained layer damping, which is more rugged and involves construction of a laminate. We've offered 10 simple, low-cost noise reduction solutions in this post that can be used to eliminate excessive noise in a variety of settings. Sound Reduction Systems has provided acoustic solutions in a variety of settings. Working in a noisy setting is unpleasant, and taking steps to decrease unwanted sound exposure is good to both productivity and safety. | Website Custom Crafted by Bright Cloud Studio.Excessive noise can be both distracting and harmful to one's health.
