Abstract

MENDOZA, Érika Cari; LAURENCIO, José Luis Legua  and  APAZA, Renée Mauricio Condori. Determination of the sound pressure level generated by the vehicle fleet in the city of Ilo, Peru. Rev. P+L [online]. 2018, vol.13, n.2, pp.14-20. ISSN 1909-0455.  https://doi.org/10.22507/pml.v13n2a2.

Introduction.

This research is focused on the noise pollution of the city of Ilo, the main purpose has been to assess and raise awareness of the disturbing acoustic situation in the city, for which monitoring and sampling techniques were applied to the railways and highways. To obtain the level of sound pressure we used a sonometer.

Objective.

To determine the levels of sound pressure that are caused by the vehicle fleet during the day and the night in Ilo.

Materials and methods.

The methodology is based on the AMC National Noise Monitoring Protocol No. 031-2011-MINAM / OGA, the use of Class I Sonometer Larson & Davis-IEC 61672 (International Electrotechnical Commission, IEC Standard).

Results.

W The results obtained according to the methodology developed can infer the following; in the five sound pressure monitoring stations over 50 dBA and 60 dBA, proposed by Peruvian regulations for mixed zones, ranging from a minimum of 42 dBA to a maximum of 118 dBA during the day. For the night time, we have to range from a minimum of 40 dBA to a maximum of 90 dBA.

Conclusions.

The results show us that sound pressure levels are for high and the average is 70.96 dB due to the flow of the vehicle fleet and the rail line that runs through the middle of the city and that does not comply with national and local.
