The purpose of this research work is to reduce the noise levels that are generated in the mill area of a PVC pipe factory, through a proposal for a prototype model based on the method of double hermetic closure with absorbent materials. In order to collect data on the noise level generated in the mill area, a pre-experimental monitoring was carried out using as a reference. RM. 375-2008-TR (Basic standard for ergonomics and evaluation of disergonomic risks) and NTP-ISO 9612: 2010 (Determination of occupational noise exposure), after which a sound pressure level equivalent to 93.6 dB was obtained, which represents a value that exceeds the maximum permissible limits established by the RM. 375 2008-TR. The prototype model has within its main structure a fundamental element (absorbent material - glass wool), which fulfills the function of reducing noise through its properties that it has to absorb all the acoustic energy that enters from the outside. For its selection, technical sheets of three materials with similarity in their physical properties were taken as a reference, given the comparison of these, glass wool is the material that was used in the prototype model, likewise its structure was supplemented with two others materials that aided resistance against humidity (RH plate) and resistance against fire or high temperatures (RF plate). Once the absorbent material was defined, work was done on the design and assembly of the prototype model based on the double hermetic closure method consisting of two noise reducing boxes. After having assembled the prototype model, a post-experimental monitoring was carried out in order to check the efficiency and the amount of decibels that it reduces: the first evaluation was carried out with the first noise reduction box, the second with the first and the second gearbox put in simultaneous and finally an evaluation was made only with the second gearbox, these measurements were made at 1m. and 2m. distance each sample yielding positive values: CR.1: 69.0 dB and 65.9 dB; CR 1 and 2: 63.4 dB and 60.4 dB and finally with the CR. 2: 70.4 dB and 68.4 dB, these values being which do not exceed the maximum permissible limits.
