This work presents a dataset of acoustic intensity vector measurements taken around a 3D-printed, upscaled model of an ear. Impulse responses of the acoustic vector were collected in an anechoic chamber in a dense grid of measurement positions around the pinna. Automated interleaved swept-sine measurements were carried out using an arc of loudspeakers, a robotic mover, a probe consisting of a pressure sensor and three anemometer particle velocity sensors, with the ear mounted on a turntable. In total, 145 unique directions of arrival and 225 measurement points were considered. Results show that the measured data is suitable for high resolution time, frequency, and spatial analyses. The full dataset containing impulse responses, ear model geometry, calibration data, and example processing scripts is shared in an open-access repository. Potential applications include the analysis and visualization of pinna-related transfer functions, as well as the validation of numerical acoustical modeling techniques.
