Sound Bites

Dr. Alec N. Salt, Ph.D., Cochlear Fluids Research Laboratory, Washington University in St. Louis  was a guest on Wind Wise Radio recently 

Dr. Salt's work is worth reading. It explains how we sense and are affected by infra-sound. Important "sound bites": 1) The ear's responses to infrasound can be enormous - over 4 times larger than to sounds you can hear presented at even the loudest levels. 2) The ear's response to low frequency noise at 45 dBA is larger than to wide band noise presented at even the loudest levels. The ear is getting "overstimulated" by low frequency noises at low dBA levels and by infrasound. 3) There are at least 4 scientifically-supported mechanisms by which low frequency sounds that you can't hear can indeed affect you. And we have more on the way! I have never been more convinced that long-term exposure to low frequency noise is really dangerous. Alec Salt Alec N.
