  • Publication number: 20240187804
    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.

  • Patent number: 11937998
    Abstract: Various embodiments of a hearing protection device and a method of forming such device are disclosed. The hearing protection device includes a first hearing protector, a second hearing protector, and an elongated connector including a first end that is connected to the first hearing protector and a second end that is connected to the second hearing protector. The device further includes a frangible attachment element disposed between a first portion of the elongated connector and a second portion of the elongated connector that temporarily connects the first portion to the second portion such that the elongated connector is in a compact configuration. The elongated connector is adapted to be disposed in an elongated configuration when the frangible attachment element is broken.

  • Publication number: 20240050279
    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.
