Análisis de emisión de ruido y ruido ambiental de la empresa Roa Florhuila S.A. en el barrio Catumare, de Villavicencio-Meta.

Abstract

The noise pollution that occurs in the Catumare neighborhood is seriously affecting the population. The neighbors of the neighborhood are attributing the Roa FlorHuila (ORF) organization as the main source of such pollution. In order to carry out this project, the methodology established in resolution 0627 of 2006 was used, where the data recorded in the noise emission measurements were obtained using an SVANTEK 977 noise analyzer (vibrations) and the SvankPC ++ program. And ambient noise during daytime and evening hours, business days and non-business days. Regarding the measurement of environmental noise, it was carried out in the park of the urbanization Latigana (Catumare neighborhood), the data recorded during the daytime were 62 dB for business days and non-business days, as for nighttime, business day It was 63 dB and 66 dB for the non-business day, exceeding the maximum allowable NPS during night time. Finally, in order to identify the processes and / or equipment that generated the most noise, 7 measurements were made in the facilities of the Roa Florhuila SA Organization, where 4 were in the pre-cleaning, drying, threshing and packaging production processes , the last two in the hopper motor, compressor room and green area of the same. The parameters measured in the study area were: equivalent sound pressure level (LAeq, t), residual noise (LAeq, residual, T) and percentile level (L90); in the results of this study, it was obtained that in noise emission at point 1 the decibels in the daytime hours are 65 dB and nighttime at 66 dB and at point 3 it was 60 dB for daytime hours and 66 dB in at night, thus exceeding the maximum permissible NPS during nighttime with the source off, it was analyzed that there is a significant influence of sound pressure levels from natural and some external emissions as leisure activities, but that are not associated with productive process. Within the company it was identified that the process with the highest NPS in is that of pre-cleaning with 82.61 dB and in specific sources (equipment) was the hopper motor with 87.93 dB. However, it is taken into account that the NPS that are registered in the area do not reach the sensitive receiver with the same intensity.
