Diseño y construcción de una cámara de insonorización para la fuente de mayor impacto en una industria metalmecánica

Abstract

In an industrial workshop, it was identified that a compressor was generating a noise level of 90 dB, which exceeded the limits allowed by current regulations and posed a risk to the surrounding environment and to the health of workers. This significantly high noise level required a solution to avoid possible sanctions and improve working conditions. To address this problem, the decision was made to build a soundproofing chamber around the compressor. The objective was to reduce the noise to a safe level for both the environment and the workers. Measurements after the installation of the chamber showed a noise reduction to 40 dB, which represents a significant decrease of 50% compared to the initial levels. When comparing the noise levels with current regulations, it was observed that the initial noise level of 90 dB exceeded both the limits established by Ministerial Agreement 097-A, which allows a maximum of 55 dB in residential areas during the day, and the occupational noise limits defined in Executive Decree 2393, which establishes a maximum of 85 dB. Therefore, the initial noise level could not only have caused a nuisance in the environment, but also serious health problems for workers, such as hearing loss. The noise reduction to 40 dB, achieved with the soundproofing chamber, not only complied with environmental regulations, but also ensured a much safer working environment. This new noise level is well below the permitted limits, minimizing any risk of penalties and ensuring that workers are not exposed to harmful noise levels. In conclusion, the implementation of the soundproofing chamber was an effective and necessary measure. It significantly reduced noise, ensured regulatory compliance and improved working conditions in the workshop, protecting both workers and the environment from the negative impact of excessive noise the environment.
