SharpnessDIN45692OverTime

class ansys.sound.core.psychoacoustics.SharpnessDIN45692OverTime(signal=None, field_type='Free')

Computes the sharpness of a signal according to the DIN 45692 standard, over time.

Note

The standard DIN 45692 does not include a method for calculation over time. The computation of the present indicator is thus not entirely covered by the standard. The method used here applies the sharpness calculation described in the standard DIN45692, using, at each time step, the specific loudness calculated according the loudness model for time-varying sounds in the standard ISO 532-1. It is the loudness model of the class LoudnessISO532_1_TimeVarying.

Class instantiation takes the following parameters.

Parameters:

signalField, default: None

Signal in Pa on which to compute sharpness over time.

field_typestr, default: “Free”

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