Interfaz gráfica para el análisis de audio y sonidos urbanos (CasRem)

Abstract

Context: The objective of this research is to create a graphical interface to analyze the sound pressure level in audio files. Method: A series of measurements are performed in different virtual learning environments, in addition to the use of the UrbanSound database containing recordings of various sound events. Results: The proposed interface consists in two options: the first one allows access to the Noise Logger Communication Tool application of the SLM-25 sound level meter where parameters such as number of samples, time, upper and lower limits, among others, can be configured. The second option allows the analysis of audio files from different environments. Conclusions: The interface provides a basis for the study and analysis of audio, especially for the estimation of noise levels. Each audio file sample analyzed has sound pressure levels ranging from 50dB to 90dB.
