It's been a little while since we've heard about the supposed dangers of electric and hybrid vehicles that shut down their engines and therefore stop producing the sound of fuel being ignited and exhaled, but the issue is apparently alive and well. Lotus Engineering and Harmon International, two heavyweights in their respective industries, have teamed up to create a new technology known as Electronic Sound Synthesis (ESS).

Lotus Engineering and Harman International have announced a partnership to develop Active Noise Control (ANC) technology for cars. Lotus will continue to develop their existing range of ANC technologies, and Harmon Becker will be the exclusive manufacturer of the systems, which could be customized and sold to OEMs as upscale infotainment sytems. ANC technologies currently being developed by Lotus include Road Noise Cancellation, Engine Order Cancellation, and Electronic Sound Synthesis.

Toyota's Crown Hybrid gets brownie points for good gas mileage, but it's apparently a troublemaker in the motor noise department. Instead of merely adding insulation to the bulkhead, Toyota engineered an Active Noise Control system to reduce engine noise inside the cabin.
