Digging down deeper into one of the links I posted yesterday reveals the existence of the World Forum for Acoustic Ecology, “an international association of affiliated organizations and individuals, who share a common concern with the state of the world soundscape as an ecologically balanced entity.” Looks like they’ve been around a while, I’m not sure how I missed them. Oops.
Via USENET comes a post from Gordon Brown that may address one of the Google questions I pointed to yesterday. A paper prepared by Casella Stanger describes the difficulty in finding sources of any low frequency noise. Note that despite the pessimistic tone of the posting, finding a source of low frequency noise can be done - just understand that it may not be easy, and in many cases may be expensive and time consuming.
Courtesy of the Noise Pollution Clearinghouse is a White Paper by noted expert Paul Schomer that discusses annoyance from noise. Again, the paper has been around for a while, but it’s worth noting because the paper gives an excellent summary of the different noise criteria used by U.S. Federal agencies, including the FAA, FHWA, FTA, FRA, and HUD.
