Automobile manufacturers have shown a great interest in an innovative noise reduction system developed by Trelleborg that uses active force cancellation. The active force cancellation system uses special actuators located near mount attachment points to generate waves at the same frequency and amplitude as those created by noise and vibrations. The system is also perfectly suited to new and more environmentally-friendly engine configurations. Trelleborg is also looking to target specific vehicles with particular noise reduction requirements. Manufacturers are also looking to reduce emissions by introducing that switch off certain cylinders when the engine is not operating at maximum power. Active force cancellation systems could be ideal for those cars whose engines create more vibration than others.
