Determination of the acoustic impact on 13th street and its hearing influence on the inhabitants of the sector, canton Manta. period may to october 2018

Investigation article

Abstract

The noise on 13th Street, from 3rd Avenue to 24th Avenue, Manta Canton was monitored in the months of May to October 2018, which were determined according to the geographical delimitation of the study area through employment of data collection instruments to perform the analysis in each of them. With the monitoring of noise, the levels and triggers and the vehicular flow were also determined. The monitoring of all these variables was carried out at times considered to be the busiest traffic from 07: 00h to 09: 00h, 11: 30h to 13: 30h and from 16: 00h to 18: 00h. The noise levels were determined with an integrating sound level meter and the measurement time was 15 minutes for each point. For the elaboration of the acoustic reports, an information system using tables was used in which all the data obtained from the measurements were processed. Noise maps showed that the factors that affect the greatest impact correspond to those of vehicular traffic, with sound pressure levels above 60 decibels. These values are attributed to the high vehicular circulation, where the registered flow is greater than 100 vehicles during the 15 minutes of monitoring. With the elaboration of the acoustic maps, a first diagnosis of the noise pollution that exists in the established area was obtained
