Hi I am new to the group but hoping someone may be able to help. I am looking at the positive effects of low frequencies in music, predominantly below 50Hz. This involves aural as well as mechanosensations. I am interested in seeing if reinforcing the low frequency content below 50Hz can help produce a more immersive listening experience at lower overall sound pressure levels (particularly when measured using the A weighting scale). Trouser flapping bass! I am struggling to find papers on the subject. Any suggestions are welcome!
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.
