WebRoughness – fluctuation strength. Roughness is a complex effect which quantifies the subjective perception of rapid (15-300 Hz) amplitude modulation of a sound. It is hard to describe in words, but below are some sound files that hoepfully will give a sense of what is meant by rapid modulation. The unit of measure is the asper. WebPsychoacoustic tuning curves can be measured using the notched-noise method. This form of measurement can take a considerable amount of time and can take around 30 minutes to find each masked threshold. [10] In the notched-noise method the subject is presented with a notched noise as the masker and a sinusoid (pure tone) as the signal.
