• Measurements are taken 3.3 ft away from the front of the unit.
• Data is valid under nominal operating conditions.
• 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.
• Reference acoustic pressure: 0dB = 20μPa.
Operating Conditions:
• Power source: 220V/60 Hz
3.3 ft.
• 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.
