Abstract:
Systems, apparatus, and methods for collecting, interpreting, and utilizing noise exposure data may include sensors to obtain an analog signal representative of impulse noise sound pressure and an analog signal representative of continuous noise sound pressure. At least one ADC may generate digital signals by sampling the analog signals at rates equal to or greater than twice the reciprocal of a minimum impulse noise rise time. Accelerometers may obtain data in close proximity to and remote from the sensors. At least one processor may include a first combining node to combine the digital signals to represent both the continuous noise and the impulse noise, a shock-artifact detection filter to identify a time frame including a shock artifact based on the accelerometry data, a frequency filter to generate a background-removed audio signal, an adaptive filter to estimate the shock artifact, and a second combining node to produce a shock-artifact-free audio signal.

Claim (Index 9):
A system for continuously collecting sound pressure due to both continuous noise and impulse noise in an environment, the system comprising:\n at least one processor, operably coupled to:\n a first sensor to obtain a first audio signal representative of impulse noise sound pressure in a first amplitude range from about 100 dB to about 180 dB, sampled at a first sampling rate equal to or greater than twice the reciprocal of a minimum impulse noise rise time in the impulse noise sound pressure; \n a second sensor to obtain a second audio signal representative of continuous noise sound pressure in a second amplitude range from about 20 dB to about 140 dB, sampled at a second sampling rate equal to or greater than twice the reciprocal of a minimum impulse noise rise time in the continuous noise sound pressure, the second amplitude range being different from the first amplitude range; \n a first accelerometer to obtain a first accelerometry signal representative of accelerometry data, \n wherein the at least one processor includes:\n a first combining node to combine the first audio signal and the second audio signal into a combined audio signal having a combined amplitude range, the combined amplitude range being larger than the first amplitude range, larger than the second amplitude range, and less than or about equal to the sum of the first amplitude range and the second amplitude range, the combined audio signal representing both the continuous noise and the impulse noise in the environment; \n a shock-artifact detection filter to identify a time frame potentially including a shock artifact based at least in part on the first accelerometry signal; \n a frequency filter to generate a background-removed audio signal by removing background noise from the combined audio signal; \n an adaptive filter to estimate the shock artifact based at least in part on the identified time frame and the background-removed audio signal; and \n a second combining node to produce a shock-artifact-free audio signal by subtracting the estimated shock artifact from the combined audio signal.
