Abstract
In one embodiment, a system for monitoring exposure to impulse noise includes a sound-sensing device, such as a microphone or other type of pressure transducer, operable to sense impulse noise, and a storage module operable to store the waveform of the impulse noise sensed by the sound-sensing device. The sound-sensing device desirably is operable to sense impulses that are greater than 146 dB, such as impulses created by construction machinery and firearms. The system also can include a processor operable to calculate one or more noise parameters of the impulse noise from the waveform, and a user interface program operable to display said one or more noise parameters selected by a user.

A system for monitoring exposure to impulse noise, comprising:
- a sound-sensing device operable to sense impulse noise;
- a storage module operable to store the waveform of the impulse noise sensed by the sound-sensing device;
- a processor operable to calculate one or more noise parameters of the impulse noise from the waveform;
- and
- a user interface program operable to display said one or more noise parameters selected by a user.
A method for monitoring exposure to impulse noise, comprising:
- detecting impulse noise;
- recording an acoustic waveform of the detected impulse noise;
- calculating one or more noise parameters of the detected impulse noise from the recorded waveform;
- and
- selecting, via one or more user-interface elements, one or more noise parameters;
- displaying the selected noise parameters;
- and
- assessing the potential hazard of the impulse noise through analysis of the selected noise parameters.
