The following quote was obtained by the news editors from the background information supplied by theinventors: “Regardless of whether it is that of a car, truck, or a van, a vehicle’s cabin should be an oasisof silence. A quiet cabin offers welcome relief from environmental noise. Such noise can be self-inflicted,i.e., it can arise from the vehicle’s own engine or from the vehicle’s tires as they grip the road. Otherenvironmental noise is that caused by external noise sources, such as horns or jackhammers.“Nevertheless, it is undesirable for the cabin to be completely isolated from the environment. Thereare, after all, sounds that are important to hear. Among these sounds, referred to herein as “desired audiosignals,” are those that signal danger. Examples include sirens from emergency vehicles, back-up soundsfrom nearby vehicles, proximity warnings from nearby vehicles and horns from nearby vehicles, includingthe sound of bicycle bells. Other examples are sounds that originate from living beings, such as animalnoises, for example, the sound of barking dogs, or the crying or shouting children. Other examples includesounds with actual semantic content. These include specific safety-related utterances such as “Help!” or“Look out!”.
