TWO-WAY VAHU INDOOR UNITS
Acoustic Data
• Measurement taken 3.3′ away from the unit.
• Measurements taken with no attenuation and units operating at full load normal
operating condition.
• Sound level will vary depending on a range of factors such as construction
(acoustic absorption coefficient) of particular area in which the equipment is
installed.
• Sound power levels are measured in dB(A).
• Tested in anechoic chamber per ISO Standard 3745.
