SoundRacer sounds for Electric Vehicles
External alert/warning sounds
Warning sounds are developed in cooperation with each vehicle manufacturer to develop the sounds to a unique sound profile for each vehicle. The sounds for electric cars are normally based on recordings from a standard 4 or 6 cylinder internal combustion engine car. In the process we will adapt the sounds to the use as warning sounds following guidelines and requirements from the authorities in the main markets for the specific vehicle. The sound control software also includes a function to mute the warning sound above a specific vehicle speed, suggested level is 18 mph/29 km/h. This function is one of 30 parameters that can be set when generating the sound files with the Windows software that are included with the sound module.
What sound do people prefer? This is a new question that the automotive industry must investigate when they develop electric cars. The survey of more than 400 people in North America and Europe found most people favoring a ”traditional engine sound” (almost 50%) or a V-8 engine sound” (20%).
What type of sound has the best warning effect? Probably a realistic engine sound since most people immediately recognize it as coming from a motor vehicle.
Example: For electric fork lift trucks we have delivered our EV Sound system with the sound of a big diesel engine.
