Calibration of low-cost sound level meters using machine learning techniques(Abstract accepted)

Published in The Journal of the Acoustical Society of America, 2018

the use of reinforcement learning techniques is explored to calibrate the sound pressure levels generated by a low-cost monitoring device using a class one sound level meter as reference in a continuous measurement setup.

Automatic Sound event recognition of traffic and community noise

Published in Universidad de San Buenaventura, 2017

Audio content analysis of real world recordings instead of common SPL measures is proposed as a technique for environmental noise evaluation. However, because of the large quantity of data that a monitoring system produces an automatic sound event algorithm was built using audio descriptors as MFCC, spectral centroid, zcr and roll off coupled with a supervised learning approach with SVM
