Ubbink 160mm Sound Attenuator ae48c_semi_rigid mold spores and other airborneIndoor sound is potentially a greater source of noise hindrance than outdoor sound as the insulation in buildings is improved. Mechanical ventilation units make sound, which may be experienced as noise hindrance, as they displace the air through the air distribution system. They emit sound by vibration and through the casing and the air distribution system. Sound is also generated as air travels through the air distribution system, including the
