Calculate Psychoacoustic Binaural Loudness (Sones)

Description

Calculates the total perceived binaural loudness based on the Pieper et al. (2021) and Moore et al. (2016) binaural summation models.

Usage

calculate_binaural_loudness(x_left, x_right = NULL, alpha_b = -0.25)

Arguments

x_left	An object of class 'SII' for the left ear.
x_right	Optional. An object of class 'SII' for the right ear. If NULL, assumes a perfectly symmetric bilateral fitting ('x_left == x_right').
alpha_b	Numeric. The binaural inhibition factor. Default is -0.25, reflecting classical normal-hearing binaural inhibition.

Value

A numeric value representing the total binaural loudness in Sones.
