Estudio de contaminación acústica de la Empresa Maderera PISMADE S.A, para la propuesta de un plan de mitigación.

Abstract

In the present study, the level of pollution was determined in the PISMADE S.A, timber company of the city of Riobamba. It was based on the monitoring of the critical points of the noise levels in the company. It was used for the statistical desing of experiments that allowed to optimize the information generated on the process that is done according to the Unified Text of Secondary Legislation of the Ministry of the Environment (TULSMA), in relation to the objectives given the characteristics of the study, the experimental desing was completely randomized, for the treatment of the results was used logarithmic averages given the scale of measurement, and for the graphs was used the program statistical Excel. The study area was divided into two zones which had a total of 12 critical monitoring points, obtaining the following results: 81.50 dB; 78.76 dB; 80.72 dB; 76.48 dB; 83.48 dB; 77.94 dB; 86.46 dB; 81.46 dB; 75.31 dB; 70.72 dB; 70.20 dB; 70.92dB at each point respectively. The data obtained produced a noise mitigation plan. It was concluded that in the PISMADE S.A Timber Company in the chosen study area there is an average noise level of 74.77 dB and a maximum of 86.46 dB, values that exceed the permissible limit so as not to affect the hearing health of the humans. It is recommended to the relevant authorities for the implementation of the noise Mitigation Plan, to carry out the necessary measures to minimize this type of environmental problem.
