The active road noise cancellation reduces overall sounds by 3-4dB. This reduction is equivalent to reducing the volume of the sound system by four steps. In general, you won’t believe tires and road creates that much sound right? But the fact is they do. They produce lots of noise. F...
In addition to Road Noise Cancellation, HALOsonic offersEngine Order Cancellation(EOC) andElectronic Sound Synthesis(ESS). EOC uses active noise cancellation technology to reduce the drone and rumble induced by the engine in the car cabin. It uses the engine RPM signal as a reference to generate ...
How the Harman solution works: the chassis of the vehicle is fitted with accelerometers; the system can measure the correlation of road vibration and resulting noise inside the cabin. An algorithm in the controller creates inverse sound waves coming from each speaker through the car's audio system...
“But we know it’s much more difficult to control noise in a large space like a car cabin compared to the relatively small area around your ears. However, through research advances and our relentless efforts to solve tough problems, we’ve achieved a level of road noise reduction that ...

How active noise cancellation works Silentium’s ARNC is similar to that found in a pair of high-end noise-cancelling headphones, but more advanced as it manipulates a larger amount of air. Up to six strategically positioned accelerometers on a vehicle’s chassis monitor unwante...
Strategic location in the middle of the city, walking distances to shops znd restaurants. However from 12am to 3am onwards you have to bear the bass sound from the club nearby. Could have requested for change of room but no guarantee of the noise cancellation. Hope the clubs can get more...
The circuit, which follows the line of the airfield's perimeter road, was established in 1968. Our car skills days will be on Wednesday 23rd April 2025 (full day) and Tuesday 20th May 2025 (2 sessions; one morning and one afternoon), Morning sessions start at 8am, afternoon sessions ...
cancellation (EOC) technology uses a non-acoustic signal such as a repetitions-per-minute (RPM) sensor representative of the engine noise as a reference to generate a sound wave that is opposite in phase to the engine noise audible in the car interior. As a result, EOC makes it easier to...
