Calculate the operation noise when external air is being fed by combining the noise when only external air is being fed as
shown in the diagram for operation noise characteristics and the operation noise of the unit as stipulated in the catalogue.

The operation noise conforms to JIS standards and constitute measurements taken in an anechoic chamber 1.5m directly
below the indoor unit. Under normal circumstances, the diagram shown above is greater owing to the effects of surrounding
noise and reverberation when the unit is actually installed.
