Motivated by the importance of the noise like labour risk in the productive activities of Aluminium Carpentry Tomas Alvarez Breto we decide to carry out a control periodic audiometric of these workers with the purpose of to determine the degree of exhibition of the same ones and to establish the most important recommendations for their protection. We intended as objective to determine the degree of auditory affectation for noise in the exposed workers to the risk, for that which the existent levels of noise were quantified in the different work positions, the clinical histories were made and he/she was carried out an exam otoscópico and a test audiometric in both hearings to define the acoustic damage and the presence of professional hipoacusia in the studied workers. When concluding the study we could check that the noise constituted a pollutant of great importance in this industry. This labour risk was above the level of security of 85 db (A) in 9 of the 13 departments with which it counts the center and it has affected the health of the workers since 77 cases they existed (78.5%) of attributable hipoacusia to the noise and a great number of workers (30.6%) exposed at high levels of noise unnecessarily for the nature of its work. For all this we recommend to take immediate measures that reduce the level of noise in the work positions where superior levels existed to those allowed, the use of the means of acoustic protection should be demanded in the exposed workers and it should be fulfilled the preventive medical exams strictly, including the tests audiometric annually.
