Neurally Based Measurement and Evaluation of Environmental Noise

This book deals with methods of measurement and evaluation of environmental noise based on an auditory neural and brain-oriented model. The model consists of the autocorrelation function (ACF) and the interaural cross-correlation function (IACF) mechanisms for signals arriving at the two ear entrances. Even when the sound pressure level of a noise is only about 35 dBA, people may feel annoyed due to the aspects of sound quality. These aspects can be formulated by the factors extracted from the ACF and IACF. Several examples of measuring environmental noisefrom outdoor noise such as that of aircraft, traffic, and trains, and indoor noise such as caused by floor impact, toilets, and air-conditioningare demonstrated. According to the noise measurement and evaluation, applications for sound design are discussed. This book provides an excellent resource for students, researchers, and practitioners in a wide range of fields, such as the automotive, railway, and electronics industries, andsoundscape, architecture, and acoustics.

Introduces parameters for noise evaluation based on the human auditory system Describes many kinds of noise characterized by the autocorrelation function (ACF) and interaural cross-correlation function (IACF) Helps to predict subjective annoyance caused by ACF and IACF parameters Includes supplementary material: sn.pub/extras
