Examples

Compute the loudness of a signal in free field.

>>> from ansys.sound.core.psychoacoustics import LoudnessANSI_S3_4
>>> loudness = LoudnessANSI_S3_4(signal=my_signal, field_type="Free")
>>> loudness.process()
>>> loudness_value = loudness.get_loudness_sone()
>>> loudness_level_value = loudness.get_loudness_level_phon()

Class instantiation takes the following parameters.

Parameters:

signalField, default: None: Input signal in Pa.
field_typestr, default: “Free”: Sound field type. Available options are “Free” and “Diffuse”.
