LoudnessISO532_2

class ansys.sound.core.psychoacoustics.LoudnessISO532_2(signal=None, field_type='Free', recording_type='Mic')

Computes ISO 532-2:2017 loudness.

This class computes the binaural and monaural loudness of a signal according to the ISO 532-2:2017 standard, corresponding to the “Moore-Glasberg method”.

Class instantiation takes the following parameters.

Parameters:

signalField | FieldsContainer, default: None

Signal in Pa on which to compute loudness. If signal is a Field, the listening assumption is diotic (same signal presented at both ears). If signal is a FieldsContainer, with exactly 2 fields, the listening assumption is dichotic (each field’s signal presented at each ear).

field_typestr, default: “Free”

Sound field type. Available options are “Free” and “Diffuse”.

recording_typestr, default: “Mic”

Recording type. Available options are “Mic” for a single microphone and “Head” for a head and torso simulator.
