Sound levels

The table describes the sound levels stated in sound pressure
level.
Sound pressure level:
Sound pressure level is defi ned as the sound level, which at an ear
level of 1.8 metres, is perceived one metre from the heat pump.
Measured in a sound measurement room without echo at an
outdoor temperature of +7ºC and 50ºC fl ow temperature.
Example:
When the heat pump is installed outside with free sound propaga-
tion the sound level drops by 6dBa with each doubling of distance.
