Note
■ Data is valid at diffuse field condition.
■ Data is valid at nominal operating condition.
■ Reference accoustic pressure 0dB = 20μPa.
■ Refer to the model specifications for nominal conditions. (Power source and Ambient temperature, etc)
■ Sound levels can be increased in accordance with installation and operating conditions.
(Operating conditions include some functional condition like Static pressure mode, air guide use, Room target temperature setting, etc and these
functions are different in accordance with each model.)
■ Sound level will vary depending on a range of factors such as the construction(acoustic absorption coefficient) of particular room in which the
equipment in installed.
■ Sound pressure level is measured on the rated condition in the anechoic rooms by ISO 3745 standard.
Therefore, these values can be increased owing to ambient conditions during operation.
