“…Cardozo and van der Veen ͑1979͒ showed that subjective annoyance results primarily from the lowfrequency component of refrigerator noise. Tamesue et al ͑2005͒ proposed a method for predicting a psychological impression of noise by using the instantaneous spectral distance. Similar evaluations of sound quality have been conducted in several mechanical engineering applications, such as automobiles, heating, ventilating and air conditioning ͑HVAC͒ systems, and wheel loaders ͑Lee et Khan and Hogstrom, 2001;Khan and Dickson, 2002͒. The psychoacoustical parameters, originally proposed by Zwicker and Fastl ͑1999͒, were designed to quantify the listener's perception and evaluation of sound quality.…”

Psychoacoustical and autocorrelation function (ACF) parameters were employed to describe the temporal fluctuations of refrigerator noise during starting, transition into/from the stationary phase and termination of operation. The temporal fluctuations of refrigerator noise include a click at start-up, followed by a rapid increase in volume, a change of pitch, and termination of the operation. Subjective evaluations of the noise of 24 different refrigerators were conducted in a real living environment. The relationship between objective measures and perceived noisiness was examined by multiple regression analysis. Sound quality indices were developed based on psychoacoustical and ACF parameters. The psychoacoustical parameters found to be important for evaluating noisiness in the stationary phase were loudness and roughness. The relationship between noisiness and ACF parameters shows that sound energy and its fluctuations are important for evaluating noisiness. Also, refrigerator sounds that had a fluctuation of pitch were rated as more annoying. The tolerance level for the starting phase of refrigerator noise was found to be 33 dBA, which is the level where 65% of the participants in the subjective tests were satisfied.

The authors propose a method for estimating and/or predicting the listening score and psychological impression of speech audibility taking into account an effect of the hearing loss due to aging under fluctuating noise. In a real acoustic environment in which audio signals are transmitted and listened to, both the sound pressure level and the frequency component of the noise show an irregular fluctuation over time. Taking the above into consideration, the index of I which reflects the mutual relationships between the spectrum level of the speech peaks and that of the noise within a short time scale, is introduced. Prediction accuracy of I is estimated, regarding how the listening score and psychological impression of speech audibility change in the case of listening to monosyllables under an actual noise environment. The predicted results are in good agreement with the observed values from psychological listening experiment that both the audio signal and the noise which passed through frequency filters simulating hearing loss due to aging are transmitted to subjects with normal hearing.
