“…Jeon et al ͑2007͒ found that the sound pressure level of refrigerator noise in an actual living room was about 10 dB higher than the level measured in an anechoic chamber 1 m from the front of the refrigerator. They also investigate the tolerable level of stationary refrigerator noise in the real living environment.…”

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.

“…Recent studies on the improvement of sound quality of refrigerators have been shown to effectively reduce annoyance. Jeon et al 3 found the fundamental sound quality characteristics of stationary refrigerator noises by investigating Zwicker's 4 loudness, sharpness, roughness and fluctuation strength, and determined dominant metrics affecting subjective responses. Sato et al 5 clarified the time varying characteristics of refrigerator noises according to the full operating cycle by using auto-correlation function (ACF) parameters 6,7 .…”

Just Noticeable Differences (JND) in sound quality metrics-Zwicker's loudness, sharpness, roughness and fluctuations strength, and Auto-CorrelationFunction (ACF) parameters-were investigated using refrigerator sounds. An original refrigerator sound was set as a reference stimulus and the reference signal manipulated in terms of sound quality for use as a comparison stimulus. Forty participants were asked to evaluate the differences in sound quality of sound pairs, and the value of JND was determined using the criteria of 75% correct answers. The results showed that JNDs of loudness, sharpness, roughness, and fluctuation strength were 0.5 sone, 0.08 acum, 0.04 asper, and 0.012 vacil, respectively. JNDs of ACF parameters such as ⌽"0…, 1 and 1 were 2.0 dB, 0.4 ms, and 0.08 dB, respectively. The results of the present study provide criteria for sound quality enhancement of refrigerator sounds, especially the amount of value for perceptual improvements. © 2008 Institute of Noise Control Engineering.

“…Whereas in the past century, the great majority of acoustic studies have concerned noise and annoyance reductions, several psychoacoustic studies now focus on improving the sound quality of industrials products, meeting consumer expectations. Different methods such as sensory evaluation, sorting tasks or dissimilarity evaluation have been used to characterize a large variety of product sounds like interior car sounds [34], car door closing sounds [26], vacuum cleaners [13], refrigerators [14], airconditioning noise [31,36], coffee machine sounds [17] and even soundscapes of train stations [38]. Intentional sounds such as alarm sounds [32,33], sonic HCI [5,8,35] and car horn sounds [20] have also been explored.…”

In this paper we focus through a series of interviews on the relation between sound and brand identity in the context of musical and sound design for the industry. The interviews showed that the sound design process involves stakeholders who have different domains of expertise, which leads to difficulties in the interaction between them. As a solution, we propose a methodological framework for designing sound identity supported by two communication tools: a deck of cards allowing the different stakeholders to share a common vocabulary concerning both brand and sound concepts, and a sound charter which is a way to communicate guidelines for sound design through the use of sound identity semantic descriptors, illustrated by sound examples.
