Desarrollo de un dispositivo de evaluación y señalización de confort acústico

Abstract

This research addresses the full development of an evaluation and signaling device for acoustic comfort in closed spaces. The design, implementation and evaluation of an own development device is presented, with the objective of offering a low-cost tool capable of applying established profiles for enclosures, such as schools, hospitals and offices. Descriptors derived from the NCB and SIL criteria were used, and an algorithm was developed to obtain the sound pressure level by octave bands and extract those descriptors. In turn, spectral compensation techniques of the acquisition system in the range of interest were applied. Finally, comparative measurements were made with a class 1 sound level meter that showed a satisfactory response, with deviations close to 1 dB in the overall sound pressure level obtained. Finally, possible improvements to the developed device and future research lines are proposed.
