Train Horns - noise info - help please!!!
Posted: Thu Jul 14, 2016 7:02 pm
Hi! wondering if anyone out there can help me out with a question regarding train horns? Someone had suggested to me that train horns provide "unidirectional noise" rather than "omni directional". As far as I can see - only ultrasound creates unidirectional noise. Trying to establish safe distance guidelines (to protect hearing) from a train horn used in a unique application - horn is stationary - not moving (as it would be on a moving train). Trying to confirm that standard noise calculations apply with train horns. Thxs.
