class ansys.sound.core.sound_power.SoundPowerLevelISO3744(surface_shape='Hemisphere', surface_radius=1.0, K1=0.0, K2=0.0, C1=0.0, C2=0.0)

Computes ISO 3744 sound power level.

This class computes the sound power level following the ISO 3744 standard.

Class instantiation takes the following parameters.

Parameters:

surface_shapestr, default: ‘Hemisphere’

Shape of measurement surface. Available options are ‘Hemisphere’ (default) and ‘Half-hemisphere’.

surface_radiusfloat, default: 1.0

Radius in m of the hemisphere or half-hemisphere measurement surface. By default, 1.0 meter.

K1float, default: 0.0

Background noise correction K1 in dB (section 8.2.3 of ISO 3744). By default, 0.0 dB.

K2float, default: 0.0

Environmental correction K2 in dB (Annex A of ISO 3744). By default, 0.0 dB.

C1float, default: 0.0

Meteorological reference quantity correction C1 in dB (Annex G of ISO 3744). By default, 0.0 dB.

C2float, default: 0.0

Meteorological radiation impedance correction C2 in dB (Annex G of ISO 3744). By default, 0.0 dB.
