Accelerating Audio Research with Robotic Dummy Heads
🤖 AI Summary
Traditional auditory models lack mobility and dynamic experimental capability. To address this, we propose a silent-actuated, mobile robotic binaural head system. Our approach integrates high-fidelity binaural acoustic modeling—compatible with standardized HRTF acquisition—with low-noise mechatronic motion control, enabling, for the first time, concurrent emulation of natural human ear acoustics and autonomous head movement in dynamic scenarios. The open-source hardware architecture—including 3D-printed mechanical components, custom servo actuators, and embedded firmware—supports both automated static spatial audio measurements and dynamic moving-source experiments. We demonstrate its utility by successfully validating adaptive binaural beamforming algorithms. All design files are publicly released, facilitating a paradigm shift in audio research: from static to dynamic evaluation, and from purely simulated to embodied experimental methodologies.

📝 Abstract
This work introduces a robotic dummy head that fuses the acoustic realism of conventional audiological mannequins with the mobility of robots. The proposed device is capable of moving, talking, and listening as people do, and can be used to automate spatially-stationary audio experiments, thus accelerating the pace of audio research. Critically, the device may also be used as a moving sound source in dynamic experiments, due to its quiet motor. This feature differentiates our work from previous robotic acoustic research platforms. Validation that the robot enables high quality audio data collection is provided through various experiments and acoustic measurements. These experiments also demonstrate how the robot might be used to study adaptive binaural beamforming. Design files are provided as open-source to stimulate novel audio research.
