Note
■ Data is valid at dif
fuse field condition.
■ Data is valid at nominal operating condition. Refer to the model specifications for nominal coditions.(Power source and Ambient temperature, etc)
■ Reference accoustic pressure 0dB = 20μPa.
■ 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.
