ACCOUSTIC NOISE POWER CHART (dBA) AT UNIT PORTS
The data shown on left chart come from measurement performed according
to ISO 5136 Standard. These data represent the sound power directly
measured at the fresh air distribution port and exhaust air from building
port. To get the actual noise level in the room, consider noise attenuation
resulting from total ductwork installation.
