A prototyping model of intelligent hearing protection device

Abstract

The occupational noise exposure problem is getting serious and the workers have low self-efficacy in using the hearing protectors during the working period. In this paper, it reveals a prototyping model, namely, Intelligent Hearing Protection Device (IHPD) as a new hearing technology to cope with current problems. This device could measure the noise level in the workplace, detect the regularity of worker in the usage of IHPD and indicate the high noise area. Meanwhile, the IHPD is required to connect with the Dosiwatch and the Integrated Noise Exposure Software (INES) to improve its functionalities. The Dosiwatch is an electronic device to display the noise level and indicate the risky area, where it helps the workers to perceive the risk of noise in a workplace. The INES receives the noise data wirelessly, plots the instantaneous noise charts and supervises the regularity of workers in using the IHPD. By the way, the technical procedure development and the typical function of electronic gadgets are significant in this invention. A prototyping model was developed to ensure the technical procedure development meets the conceptual design of IHPD, dosiwatch and INES.
