Acoustic Warning Device Evaluation

Acoustic warning devices truly pose a three-horned dilemma: a device must be capable of alerting motorists to the train's approach, not annoy residents, and not damage train crew hearing. This project examines new technology, such as hypersound, that might be able to resolve this dilemma and the combination of acoustic characteristics that might be manipulated to achieve an effective warning that does not annoy or damage crew hearing. This project is examining the spectral characteristics of devices, timing and duration of sound and no-sound intervals, etc., to improve device effectiveness.
