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.
