I'd be interested in any references indicating deleterious effects on hearing of high amplitudes at LF, if anyone comes across any cheers ppl Dr. Peter Lennox Senior Fellow of the Higher Education Academy Senior Lecturer in Perception College of Arts University of Derby

Well, it's not a secret that most live sound engineers, when faced with a 99dB(A) rule, will mix into the A curve, i.e. crank up the bass a lot. So there is plenty anecdotal evidence for more bass resulting in less weighted sound pressure. For more perceived loudness, mixing in some typical loudspeaker-like artificial distortion has prevented me from getting beaten up at a "95 at the mixer" open air metal concert. Don't ask me who came up with that rule, for that kind of music. But I've heard medical research hint at low frequency exposure having a very damaging effect across the entire hearing spectrum, which means that we are mixing around the rules but are actually endangering our audiences. Be sure to check the literature for this problem, to get a balanced view. -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
