Acoustic data
Sound Pressure levels
•
Measurements are taken 3.3 ft away from the front of the unit.
•
Sound pressure levels are measured in dB(A) with a tolerance of ±3.
•
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
Operating Conditions :
•
Power source: 220V/60 Hz
•
Sound level will vary depending on a range of factors including the construction
(acoustic absorption coefficient) of a particular room in which the unit was installed.
