ADAPTIVE AUDIO CONTENT GENERATION SYSTEM

摘要

An alarm signal alerts individuals who may be in the vicinity of the reversing vehicle and alerts the vehicle operator when the alarm signal is not be audible due to high ambient sound levels or detritus covering the alarm transducer. The background noise level in proximity to the vehicle is monitored. The level of the alarm signal is increased as the ambient (or background) sound level rises. Conversely, the level of the alarm signal is reduced as the background noise level decreases. The alarm signal is changed in volume, frequency, or both based on velocity of the vehicle. In other exemplary embodiments, the frequency content of the alarm signal is modified if the spectral profile of the ambient sound field contains spectral components that may mask the alarm signal.
