Description

A dataset of acoustic impulse responses for microphones worn on the body. Microphones were placed at 80 positions on the body of a human subject and a plastic mannequin. The impulse responses can be used to study the acoustic effects of the body and can be convolved with sound sources to simulate wearable audio devices and microphone arrays. The dataset also includes measurements with different articles of clothing covering some of the microphones and with microphones placed on different hats and accessories. The measurements were performed from 24 angles of arrival in an acoustically treated laboratory.

All impulse responses are sampled at 48 kHz and truncated to 500 ms. The impulse response data is provided in WAVE audio and MATLAB data file formats. The microphone locations are provided in tab-separated-value files for each experiment and are also depicted graphically in the documentation.

The file wearable_mic_dataset_full.zip contains both WAVE- and MATLAB-format impulse responses.
The file wearable_mic_dataset_matlab.zip contains only MATLAB-format impulse responses.
The file wearable_mic_dataset_wave.zip contains only WAVE-format impulse responses.
