Abstract:
1. A sound pressure level prediction method, the method comprising: acquiring, using an acquisition unit, sound pressure levels for a first fan measured at a plurality of locations forming a hemispherical path around the first fan, and at least one sound pressure level for a second fan, the second fan being different from the first fan and the at least one sound pressure level being measured at the same location as at least one of the plurality of locations, along the hemispherical path, used for measuring the sound pressure levels for the first fan; and predicting, using a prediction unit and based on the acquired sound pressure levels for the first fan and the at least one sound pressure level for the second fan, a sound pressure level for the second fan at a location along a hemispherical path around the second fan, where the sound pressure level for the second fan at the location along the hemispherical path around the second fan has not yet been measured.
