A sound monitoring system for collecting and processing an environmental noise level surrounding a work machine is disclosed. The sound monitoring system may include an acoustic sensor having a plurality of microphones arranged into a signal detection array to capture the environmental noise level and generate an acoustic output signal. Additionally, the sound monitoring system may include a controller communicably coupled to the acoustic sensor and programmed to perform a signal processing to identify a first portion and a second portion of the acoustic output signal. Furthermore, the controller may be programmed to generate a controller output signal based on the first and second portions of the output level. A speaker may be located on the work machine and communicably coupled to the controller such that the speaker receives and emits the controller output signal.
