Abstract: In some examples, a system includes an article of hearing protection assigned to a worker, and a portable computing device assigned to the worker; a remote computing device communicatively coupled to the portable computing device, the remote computing device configured to receive sound level data that indicate different sound levels at different, respective locations of a work environment; determine, based on location data received from the portable computing device, an amount of sound received by the worker over a period of time; identify an updated location in the work environment having a sound level that is different from a current location, based at least in part on the article of hearing protection, the amount of sound, and the sound level data that indicates different sound levels at different, respective locations; and generate a notification that instructs the worker to move from the current location to the updated location.

Abstract: A hearing protection system is provided. The hearing protection system has a first active hearing protection system. The first active hearing protection system is level-dependent. The hearing protection system also has a second active hearing protection system. The second active hearing protection system is level-dependent. Each of the first and second active hearing protection systems are configured to operate in an independent mode and a dual-protection mode. A dual-protection mode level dependent function of the second active hearing protection system is different than an independent mode level dependent function.

Abstract: Systems and methods for check a relative sensitivity of two or more microphones of a hearing protection device include sensing ambient sound using two or more microphones of the hearing protection device and sampling the ambient sound. The samples of the ambient sound may be used to determine whether the ambient sound is adequate for determining microphone sensitivity and to determine whether a threshold relative sensitivity of the two or more microphones is reached. A pass or fail indication may be provided to a user based on whether the threshold relative sensitivity is reached.

Abstract: 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.

Abstract: A sound attenuating apparatus may include a replaceable sound attenuating device and an electronic receiver configured to mate with the replaceable sound attenuating device. The replaceable sound attenuating device may include a sound attenuating material having an embedded sensor element. The sensor element may have a property that corresponds to a type of replaceable sound attenuating device. The electronic receiver may detect the property of the sensor element. A computing device may determine the type of the replaceable sound attenuating device from the property of the sensor element and perform one or more operations based on the type of replaceable sound attenuating device, including audio control, safety warnings, personal attenuation rating determinations, and the like.
