No matter it is a medium sized office building, a small house or a huge manufacturing amenity, HVAC systems play a vital role in offering much required temperature regulation and airflow throughout the structure. Nonetheless, HVAC systems frequently generate noise pollution, generally in two unique ways.
HVAC systems create major gusts from blowers or fans to empower air throughout the system. The ductwork works like a highway for noise and reverberations. Nose reduction panels are necessary to lessen noise to levels tolerable to the building occupants.
Another way HVAC systems generate noise is through vibration. With time, the supports and hangers can loosen, enabling the ductwork to sway and vibrate. The vibration may start as a slight rattling sound, and if it is left untreated, ultimately works its way to higher and unpleasant decibel levels according to the noise measurement chart.
To successfully insulate a HVAC system from undesired noise pollution, both the problems should be addressed. How can you address both the causes of HVAC noise pollution and adhere to the building fire codes? One of the more popular options is Mass Loaded Vinyl that comes with a foil facing.
Another solution after db noise level measurement would be a Mass Loaded Vinyl (MLV) product that has both the quilted fiberglass decoupler and a foil facing. Any component of the reflected sound wave will be more dispelled into the fiberglass absorber. It is suggested to always check with your local building codes before the installation of an noise suppressor or MLV product.
MLV can solve various challenging noise problems, and HVAC is one of the various applications where it has some value when it comes to HVAC systems noise control. Next time your HVAC system is too much noise, just keep in mind you can cool it off with these noise reduction products.
