  • Apparatus and method for testing attenuation of in-use insert hearing protectors
    Patent number: 5757930
    Abstract: The device of the present invention is designed for the purpose of providing a system for conducting objective assessment of the actual or "real world" attenuation which is provided by insert-type hearing protection (IHP) devices. The device is constructed to serve as the input device to any commercially available noise dosimetry instrument or sound level measuring device. A miniature microphone is mounted on, or embedded in the proximal surface of the IHP which is to be inserted in the ear or upon the ear of the user. The miniature microphone is hard wired to a miniature jack which is mounted on, or embedded in the distal surface of the IHP device. A cable connects to the jack on the outside of the IHP device and to the input of the noise dosimetry instrument or sound level measurement device.
