摘要:
A system and method for automatic detection and signaling of the connection status of a headset used with telephony or other multimedia application software running on processor-based hosts using digital signaling are disclosed. The signaling system includes a signaling module for communicating with the host and a headset selectively in communication with the signaling module for use with the application software. The signaling module monitors the headset connection status, generates a status signal, and transmits the status signal to the host for determining the state of host and/or the application software. The signaling module may include a connection status detector and a status signal generating processor. A signal indicating that the headset is disconnected may pause or terminate an executing application or prevent the application from being executed. A signal indicating that the headset is connected may resume a paused application or allow the application to be executed.
摘要:
A method and apparatus for monitoring and controlling exposure to noise related to a headset are described. The method includes sampling an input sound signal to produce samples of the input sound signal, calculating from these samples a headset sound level corresponding to the input sound signal, calculating cumulative exposure of a headset user to the headset sound level at a specific point in time, and calculating a gain adjustment for the input sound signal to ensure that the total sound to which the headset user will be exposed during a selected time period is within the regulatory maximum level. Advantageously, the method and apparatus of the present invention allow accurate real-time monitoring of cumulative exposure to headset noise and real-time adjustment of headset gain to ensure compliance with regulatory maximum sound exposure levels.
