Active noise cancelling (ANC) is a software process that uses existing in-vehicle infotainment hardware to eliminate undesirable noise within the interior of a vehicle. This elimination technique is known as harmonic order reduction, where unwanted audio signals are identified by sensors and filtered out of the overall interior vehicle sound. [ 3 ]

Structure-borne noise is attenuated by isolation, while airborne noise is reduced by absorption or through the use of barrier materials. Vibrations are sensed at the steering wheel, the seat, armrests, or the floor and pedals. Some problems are sensed visually, such as the vibration of the rear-view mirror or header rail on open-topped cars.

All Airbus A321LRs, like the one my parents are flying to Paris, for example, have the same window layout, but different airlines may set up their cabins differently, meaning the seats may have ...
The interior of the new Saga consists of all-new parts and components, as well as borrowed ones, with only minimal carryovers from the outgoing generation. [30] Proton had also invested considerably in solutions to reduce transmissions of noise, vibration and harshness into the cabin, in an effort to create a more mature and refined Saga. [31]
Research shows that window seats are more isolated and are furthest away from the aisle, where passengers and crew often walk by and can more easily spread germs. Of course, if you really want to ...
