Abstract

Воспринимаемая громкость аудиосигнала измеряется с помощью модификации спектрального изображения аудиосигнала как функции от эталонной спектральной формы так, чтобы спектральное изображение аудиосигнала ближе соответствовало эталонной спектральной форме, и определения воспринимаемой громкости модифицированного спектрального изображения аудиосигнала.
