The use of noise silencers is a necessary way to control noise coming from engine combustion, fans and blowers. Diesel-powered equipment, with its many advantages, does have the drawback of being somewhat noisy.When placed in a room/enclosure with poor sound-absorption characteristics, this noise can be deafening and quite disturbing to those who find themselves in its environs. When looking at generator enclosure designs it is best to insist the enclosure structure is engineered in such a way that there are no points at which noise measured is more than 3-5 db(A) higher than the promised average. Don't mix it up with the damping (attenuation) of high frequencies of air. These acoustic building ventilation systems are a combination of noise attenuation solutions coupled with good ventilation practices. These high flow solids handling pumps deliver first-rate efficiency and include run dry options. To reduce sound coming through walls and floors, caulk around light fixtures, receptacle boxes, and door casings. Architectural Acoustics, Second Edition presents a thorough technical overview of the discipline, from basic concepts to specific design advice. Once the sound attenuation approaches 40 dB(A) of reduction (40 dB(A) is considered the maximum economically viable reduction by a standard prefabricated enclosure) it is not unusual to see more enclosure space devoted to air handing as to the muffling of the engine itself. The desired effect is to reduce unwanted noise like echoes or high-pitched laughing. Typical sound attenuated generator enclosures consist of panels that are multi-layered composite treatments comprising of an impervious exterior layer as well as a layer of porous sound absorption material facing towards the inside of the equipment. The ratio between direct and reverberant sound would be very large. As a result you may choose from a selection of standard or custom engineered duct silencers that will satisfy the requirements of each application.
