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
noise-from outdoor noise such as that of aircraft traffic and trains and indoor noise such
as caused by floor impact toilets and air-conditioning-are 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 and soundscape
architecture and acoustics.
