About company

Recalm is a technology company that develops innovative acoustic devices for active noise reduction in vehicle cabins. The company reduces annoying and harmful noises for humans through targeted anti-sound by up to 75% in the frequency range <500 Hz. Their developed ANC software then generates signals with opposite polarity to this source. Recal algorithm selectively reduces annoying and damaging machine noises for humans. At the same time, acoustic signals remain audible, e.g. while driving backward instructions from the foreman, walkie-talkies, mobile phones and radio (selective). It offers the click-on solution for the headrest coming as original equipment or technical upgrade.
