Impulsive acoustic noise in three different scenarios

We acquired the acoustic data in three different scenarios using a setup with four channels (microphones) without audio source (only noise):1. Indoor scenario: A silent environment inside an empty auditorium;2. Hall scenario: A mixed indoor/outdoor environment at the same auditorium hall;3. Outdoor scenario: Outside the auditorium.The setup is a low-cost setup with a ReSpeaker Core v1 (MT7688) board using the Analog-to-Digital Converter (ADC) AC108 with four ADC delta-sigma, 48 kHz of sample rate, and 3.3 V voltage range, with four microphones connected to a Raspberry Pi 3 (model B) processor to collect and store the data.If you used the datasets, please consider citing our paper: "Acoustic Impulsive Noise Based on Non-Gaussian Models: An Experimental Evaluation", https://doi.org/10.3390/s19122827
