Abstract: A method for using an earpiece (800) in a work environment is provided. The earpiece (800) attenuates sound from the work environment to the user's ear. The earpiece (800) includes an ear canal microphone (820) for measuring a sound pressure level in an ear canal of the user. Sound pressure levels are measured periodically while in the work environment. Each measured sound pressure levels is stored in memory (127) of the earpiece with time and location information. The sound pressure level information is downloaded to a database (1704) when the earpiece is removed from the user ear for recharging. The sound pressure level information is analyzed and any potential noise compliance issues in the work environment are identified.

Abstract: Provided herein is a positive air pressure facemask, a multi-staged filter system for a positive air pressure facemask, and exemplary methods for replacing the filter system of a positive air pressure facemask while the mask is in continuous use and actively worn by a user. The multi-staged filter system includes a front filter assembly having a plurality of removable filter layers for collecting debris and particulate matter on the exterior of the filter system, a blower assembly, and at least two staged filter inserts contained in the housing of the filter system. The staged filter inserts are easily replaceable and can be changed without requiring the user to remove the facemask or to be exposed to the ambient air.
