Subject: Re: Audibility of fire alarms From: federico avanzini <avanzini(at)DEI.UNIPD.IT> Date: Mon, 20 Sep 2004 10:01:35 +0000Brad, a good general reference for auditory warning/alarm design is N.A. Stanton and J. Edworthy, eds., Human Factors in Auditory Warnings, Ashgate, 1999. The focus is mainly on information coding in non-verbal warnings, perceived urgency etc. but as far as I remember there's also some discussion about audibility of alarms for hearing-impaired listeners. Also, a quick googling returned T. Grace, Improving the Waking Effectiveness of Fire Alarms in Residential Areas, Fire Engineering Research Report 97/13, School of Engineering University of Canterbury, New Zealand, May 1997. http://www.civil.canterbury.ac.nz/fire/pdfreports/Grace.pdf Don't know about the contents, but the title is nicely on topic :-) Regards, Federico Brad Ingrao wrote: > Does anyone of any research that identifies the acoustic > characteristics needed to arouse people from sleep.
