s07527 The impact of decorrelated low-frequency reproduction on auditory spatial imagery: Are two subwoofers better than one?William L. MartensUniversity of Aizu Aizu-Wakamatsu, Fukushima Japan
In contrast to sound reproduction systems using one subwoofer,
the use of two subwoofers enables the presentation of decorrelated
low-frequency signals that produce useful variation in auditory spatial
imagery. Controlled listening experiments confirmed that this variation
is lost when decorrelation is not reproduced at low-frequencies, and that
this loss is particularly great for signals exhibiting negative values of
cross correlation.
