Operating Noise of Indoor Units
7.1.1 Difference between Catalogue Data and Actual Noise
Operating noise differs depending on the place of measurement (room) because of the various
degrees with which the room reverberates the sound. To determine the amount of reverberation
under uniform conditions, the unit has been measured in a dead room with results having been
compiled in the below table. The actual sound produced in unit operation can be determined from
Table 1.
Sound pressure rise due to room reverberation (Higher than catalogue data)
