Abstract
A laser level system includes a digital laser receiver having a photodetector sensor reception window configured to detect a laser beam at a levelling point. A wireless audio transceiver transmits alignment-related audio cues to wireless headphones worn by an operator. The headphones include a noise-cancelling digital signal processor selectively activated only when the laser beam is detected, enhancing clarity of the audio cues during alignment while allowing ambient sounds to remain perceptible when the beam is not detected. Selective activation may be based on detection state and may integrate with headphone control logic.
