Development and Validation of a Method for Predicting the Perceived Naturalness of Sounds Subjected to Spectral Distortion - Having partitioned distortion into linear and nonlinear distortion and having explored the degree to which such distortions degrade the perception of naturalness, the authors now propose a model to explain the perceptual effects of linear distortion, namely, irregularities in the frequency response. Using the data from 168 filtering conditions, a perceptual model based on excitation patterns has been developed to predict subjective judgments. The model is based on the difference between the excitation patterns for undistorted and distorted pink noise. Two validation experiments supported the model.

Why Are Commercials so Loud? -- Perception and Modeling of the Loudness of Amplitude-Compressed Speech - According to urban legend, commercials are broadcast with higher loudness levels than programming. An empirical study confirmed that four-band compressed speech sounds louder than uncompressed speech by as much as 3 dB when the rms levels are matched. An audio engineer can control only the perceived loudness of broadcast program material if a loudness meter is available for monitoring the program. However, loudness models require significant computational power if used in real time.

Measuring and Predicting the Perceived Quality of Music and Speech Subjected to Combined Linear and Nonlinear Distortion - A new model is presented for predicting the perceived quality of audio signals subjected to both linear and nonlinear distortion. Earlier research produced metrics for predicting the effects of linear distortion (frequency response irregularity) and nonlinear distortion (production of spurious spectral components). The new model, which includes both metrics, provides predictions that correlate highly with results of subjective tests: Correlations were 0.90 for music and 0.85 for speech.
