In another new advance for the Crown Hybrid, Toyota will be equipping the car with three noise canceling speakers in an effort to ensure maximum quietness in its cabins.
Called the “active noise control” system, it detects noise via three microphones and generates anti-phase signals to counter it. The system can reduce noise by 5 to 8dB, according to the company.
The Crown Hybrid uses the same hybrid engine system as Toyota’s high-end Lexus GS but generates more noise due to the tuning for better milage. The noise cancellation system is Toyota’s high-tech solution to achieve a similar level of quiet as its luxurious cousin.
The system is in constant operation, sending out its anti-phase signals through two speakers on the front doors plus a woofer in the rear. It even continues to function while music is playing.
