Active noise reduction technology | enjoy the quiet space during the journey


Silentium active noise reduction technology ANC, whose core is an algorithm. The sensor monitors the noise signal, and the core algorithm, through calculation, produces the "anti-noise" sound signal, which eliminates or reduces the original noise by the superposition of the opposite frequency sound wave. which is very different from the traditional passive noise reduction method, ANC can adaptively track the noise spectrum changes, so as to achieve the effect of noise reduction. Active noise reduction technology of Israel Silentium is in the absolute leading position in the world.

honrock and Active Noise Reduction

 Honrock's strategic investment in israel's proactive noise reduction technology company Silentium, become its first chinese shareholder in 2016 and its only partner in the domestic railway industry. This advanced layout is based on future passenger comfort requirements for high-speed rail will certainly improve this judgment.


Silentium Current achievements in domestic rail industry

The research and development cooperation between honrock and Zhongche Group in VIP seat active noise reduction has been carried out, and the display of active noise reduction technology in laboratory and real car has been completed, and the noise reduction effect can reach 3~5 dB. in real car experiment. This project is mainly aimed at the active noise reduction in the head area of passengers in VIP passenger room, using the QBDT technology developed by Silentium company. we are currently in the design stage of the prototype seat.

The technical analysis of the noise sources in the cars is also carried out by honrock for the metro vehicles, especially the investigation of the noise characteristics of the air conditioning outlet is done, and the technical scheme of noise reduction is formed.

Maybe you've been on an airbus for more than a dozen hours, maybe you' ve been driving for hours, maybe you've been on a train for dozens of hours, and that's a lot of hard work. Besides boat fatigue, there's a lot of fidgety noise. Enjoy a moment of quietness unless you close doors and windows, close all appliances, or buy expensive noise-reducing headphones. And these are no longer problems, whether you drive or fly, a small chip can solve the disturbing noise. Powered by Silentium &Honrock!
