Abstract
A system includes an active noise-reducing headset and an alert processor. The active noise reducing headset includes a communication module that establishes a wireless communication link, a microphone that generates a microphone signal in response to ambient noise, a speaker, a noise reduction circuit that generates a noise reduction signal in response to the microphone signal, and a control circuit that receives an incoming alert signal from the communication module and plays the alert signal over the speaker. The alert processor includes a second communication module that establishes the wireless link with the active noise-reducing headset, and a controller that receive an incoming alert signal, generates an alert notification in response to the alert signal, and transmits the alert notification to the active noise-reducing headset.
