Consumers haven’t found much to be unhappy about with electric cars. They can reach the same speeds of their gas-guzzling counterparts. The car’s lithium-ion battery can travel a commuter’s daily average mileage on a single charge–and they are getting better with constant technical advances. You can still get the same great makes and models you love for similar to lower prices due to tax credits, for instance BMW car prices can be cut by nearly $7,500–making them affordable for a wide range of buyers.
However, there is one aspect of electric cars that has been a cause of concern. They’re quiet. While that can be considered a blessing in contrast to the sounds emanating from combustible engines, electric cars can be almost too quiet. Since the internal operations of the vehicles are run on electric pulses they can be devoid of nearly all sound presenting safety issues for pedestrians and others.
Sounding the alarm are advocates for the blind, who potentially would be most affected since they rely on sound to travel around cities, especially when crossing intersections. But all pedestrians can be at risk, since not everyone takes the time to look both ways before crossing.
Electric car makers have teamed up with blind advocates like The National Federation of the Blind to come up with a solution. They have begun outfitting electric cars with sound technology that will alert pedestrians. The sound effects kick in when the car is moving forward or in reverse. Makers are even considering creating sound for when cars are idle too.
Sound is to be generated from a synthesizer under the hood of the vehicle and broadcasted through speakers in the wheel wells. It will cease when the vehicle reaches around 20 mph when the sounds from the tires and wind will be enough to make the car’s presence known. And, passengers will be unable to hear them in the cabin. Challenges will persist, however, as electric car makers must formulate sounds that will alert, but at the same time, not annoy.
