ABSTRACT:
A visual feedback system that activates a visual display when the sound pressure level from a headset attached to the system exceeds a preset level is provided, along with a method of using the same. The visual feedback system is interposed between the audio source and the headset and is either integral to a specific headset or coupleable to any of a variety of headsets. If a non-integral headset is used with the visual feedback system, the system is matched to the characteristics of the selected headset, for example using a selector switch or via a calibration process. During operation, the visual feedback system illuminates a display (e.g., an LED) whenever the sound pressure level from the attached headset exceeds the preset level. The visual feedback system can be implemented using analog or digital circuitry.
