Noise power level in the vehicle interior under different conditions

We acquired the acoustic data (sound power level in dBV) in the vehicle interior (Citroen C4 Lounge) using a setup without an audio source (only noise). 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. It was used only the first channel (only one microphone). This setup is positioned on the panel car, inside the cabin, similar to the position of the multimedia microphone.

本数据集采集了雪铁龙C4 Lounge车型车内的声学数据（以dBV为单位的声功率级），本次采集未搭载外置音频声源，仅采集环境本底噪声。本次采用低成本采集方案：基于ReSpeaker Core v1（MT7688）开发板，搭载采用4路ΔΣ模数转换器（Analog-to-Digital Converter, ADC）AC108的硬件模块，采样率为48 kHz，电压量程为3.3 V；该方案配备4路麦克风，通过树莓派3（B型）处理器完成数据采集与存储工作。本次实验仅启用第一通道（单路麦克风）进行采集。采集装置安装于车辆座舱内的中控台面板上，与车载多媒体麦克风的安装位置相仿。若您使用本数据集的任意内容，请引用以下学术论文：Flor, D.; Pena, D.; Pena, L.; A. de Sousa, V., Jr.; Martins, A.
