In the fields of acoustic research and industrial inspection, sound is no longer just a signal to be “heard”,but information that can be “seen”.How to visualize, analyze, and quantify sound has been a long-standing pursuit for research institutions and engineers alike. Today, leveraging its deep expertise in acoustics, CRYSOUND has launched the new SonoCam Pi product series—not just an acoustic camera, but an open acoustic platform, redefining the future of acoustic measurement and imaging.

Making Acoustic Experiments Simpler And More Efficient

In recent years, microphone arrays have been rapidly adopted in acoustic research. However, research institutions commonly face the following challenges:

• Traditional systems are expensive and offer a limited number of channels.
• Array design and algorithm development are complex and time-consuming.
• In-house array development lacks mature supply chains and integrated hardware-software support.

To address these challenges, CRYSOUND leveraging nearly 30 years of expertise in acoustic testing and signal processing, has developed the SonoCam Pi platform—an affordable, open, and programmable acoustic solution. It enables researchers, engineers, and university students to enter the world of acoustic imaging and algorithm validation more quickly, flexibly, and cost-effectively.
