Beschreibung
Zusammenfassung:	A hearing protection assessment module for a Personal Protective Equipment (PPE) device. The module includes an ambient sound receiver that receives an indication of an ambient sound. The module also includes an experienced sound receiver that receives an indication of an experienced sound, wherein the experienced sound is a sound experienced by a user while wearing the PPE in the environment with the ambient sound. The module also includes a Field Attenuation Rating (FAR) calculator that, based on the ambient and attenuated sound indications, calculates a personal attenuation rating for the PPE device.
