There is a wealth of information regarding the negative effects of Low frequency noise but most of it relates either to vibration issues or sleep related problems. The low frequencies produced in concerts have had very little specific health related research. I recently had a long conversation with one of the major custom earplug manufacturers who was of the opinion that the low frequency levels were of little concern at rock and pop concerts and that is was the A weighted band that we should be concerned with. As I am looking at ways of reducing the A weighted levels by increasing energy in the sub 50Hz region I am looking for research done that may relate to this small but interesting area. I have over the past ten years been using sub to help produce a more immersive experience at low levels. I was wondering if any of the group had tried anything similar. I know there has been research done on gaming chairs using vibration but has anyone done work with sound waves?
