BKA WN is an acoustic signaling device that emits a distinctive multi-frequency sound, called “white noise” (Shhh-Shhh), similar to a rustling sound. Thanks to the wide spectrum of frequencies generated, this noise is easily perceived by human hearing (regardless of individual hearing sensitivity).
The white noise emitted by the BKA WN reversing alarm is directional and is therefore immediately localized. It is limited to the danger zone only, and this makes it suitable for night-time services or for vehicles working on construction sites in residential and urban areas.
