Abstract: The present disclosure provides an article of personal protective equipment (PPE) associated with a worker. The article of PPE includes at least one sensor configured to generate signals indicative of a sensed variable related to at least one of the worker and the work environment. The article of PPE further includes a processor communicably coupled to the at least one sensor and at least one other article of PPE associated with one other worker. The processor is configured to receive the signals from the at least one sensor. The processor is further configured to determine one or more messages corresponding to the signals. The processor is further configured to transmit the one or more messages directly to the at least one other article of PPE based on at least one of a push communication protocol, a pull communication protocol, and a continuous communication protocol.

Abstract: The invention relates to a system comprising a hearing protection device (13) configured to be worn by a user (10); one or more audio output devices (26) configured to generate one or more audio signals, a computing device (60) comprising a memory and one or more computer processors, wherein the memory comprises instructions that when executed by the one or more computer processors cause the one or more computer processor to: —select a training configuration (25) that defines a set of audio events (74A) that correspond to a set of user reactions (74B), —send a set of control signals to the one or more audio output device (26) that cause the one or more audio output devices (26) to simulate the set of audio events (74A), —receive reaction data (74C) that indicates whether the user (10) provided the set of user reactions (74B) to the set of audio events (74A); and —perform at least one operation based at least in part on whether the user (10) provided the set of user reactions (74B) to the set of audio events (74A) while wearing the hearing protection device (13).
