Pico-Driven Ultrasound Enables Scaled Acoustic Model of Home Stereo
An audio engineer used ultrasonic frequencies and a Pi Pico microcontroller to create a scaled acoustic model of a home stereo system, allowing visualization of sound wave behavior using Schlieren imaging. The setup includes a turntable-mounted array of ultrasonic transducers and a stroboscope to capture dynamic wave patterns, enabling detailed analysis of how different speaker configurations interact with room acoustics. The experiment highlights how soft furnishings affect sound diffusion, particularly for directional speakers like soundbars. The project provides a practical, visual tool for understanding and optimizing audio environments.
