ToneToNoiseRatioForOrdersOverTime

class ansys.sound.core.psychoacoustics.ToneToNoiseRatioForOrdersOverTime(signal=None, profile=None, order_list=None)

Computes the ECMA 418-1/ISO 7779 tone-to-noise ratio (TNR) for specific orders over time.

This class computes the TNR, as defined in ECMA 418-1 and ISO 7779 standards, following specific orders over time in a given time-domain signal and its RPM signal.

Class instantiation takes the following parameters.

Parameters:

signalField, default: None

Signal on which to compute tone-to-noise ratio.

profileField, default: None

RPM profile corresponding to the input signal.

order_listlist, default: None

List of the order numbers, as floats, on which to compute the tone-to-noise ratio.
