Abstract

The Acoustic Dosimeter developed by Incon Electronica consists of a personal device, and can be attached to the waist or in the worker's clothing. However, the sensor (microphone) must be fixed near to the ear in order to accurately grasp the noise felt by the worker. This equipment allows an assessment of audible noise levels that the worker is exposed throughout their workday. The Acoustic Dosimeter, reports the percentage of the daily noise exposure that the employee is submitted in accordance with the regulations, also performs the measurement of noise intensity versus time of exposure, with wide application in compliance with the Labor Security Industry standards and the regulations regarding the granting of benefits by the National Social Security Institute (Instruction 39/2000 INSS). According to statistics of the Ministry of Social Security (MPS 1 DATAPREV) in its 2004 report - Work Accidents according to the International Classification of Diseases (ICD), the cause hearing damage (H90 and H91) represented 3.2% of total accidents registered by the MPS. Due to its importance, this equipment must always be calibrated according to the legislation that working environments are subject (NR-15) to the maximum allowable amount does not exceed 100%. Through market information, audible noise monitoring equipment known in the market are all imported and expensive, moreover, it should be noted that there is a limited number of manufacturers in this segment in the global market when compared with the manufacturers of other lines of nearby equipment. Based on this information the Incon Electronica has developed a dosimeter with national technology supported by FAPESP through the PIPE line (Process 2010 1 52713-2), which financed 60% of the project. The objectives in the development phase have been achieved getting an innovative product with competitive value to domestic and international markets. (AU)
