Re: Shape of background noise

[Ralph Muehleisen <muehleisen@xxxxxxx>]

While useful for studying the changes in background noise over the last 65 years, the last reference is probably not applicable to characterization of nearly any modern built environment.  I believe that changes in building construction and building systems along changes in outdoor environmental noises make such a dated study inappropriate.  I would suggest that you avoid references before the mid 80's.
