Abstract
Headphones with acoustically resistant ear cups, an external noise sensor mounted thereto that monitors ambient noise, and internal sensors to monitor noise within each ear cup are disclosed. A processing system monitors the external and interior sound detected by the sensors and compares the level inside the ear cups with the detected level of ambient noise. It activates a transducer such as a vibrator, buzzer, or light as needed to indicate when the level within the ear cups has exceeded the predetermined criteria thereby indicating improper fit of the headphones. Alternative embodiments include wirelessly communicating the collected data to an auxiliary computer for remote data collection, storage and monitoring. The headphones may also provide a sound dosimeter; bandpass filtering; automatic noise reduction with feed forward and/or feed back; wireless voice and data communication; and a voice activated switch, all using elements of the headphone fit detection circuitry.
