Abstract

A monitoring system can include an earpiece, a database with stored earpiece characteristics data, and a microphone to receive a plurality of signals where each signal of the plurality of signals can represents a respective sound pressure level of sound pressure values over a time duration. The system can also include a processor and a memory coupled processor, the memory having computer instructions which when executed by the processor causes the processor to perform the operations. The operations can include determining exposure time duration when a signal of the plurality of signals exceeds a sound pressure level threshold value, retrieving a subset of data of the stored earpiece characteristics data, and modifying an acoustic output of the earpiece in accordance with the subset of data of the stored earpiece characteristics data.
