How Does the Laser-Assisted See-Through Technology Work?

The innovative technology employs a combination of passive sonic detection and ranging (SODAR) algorithms, the Helmholtz equation least squares method, and computer tomography (CT) scanning. Through these combined approaches, the technology can visualize sound fields within solid structures and track changes in the sound field over time. The potential applications for this technology are vast, ranging from industrial noise control to architectural acoustics.

Experimental Validation and Practical Applications

This technology has undergone rigorous testing and validation, demonstrating its effectiveness in real-world scenarios. One application example is the observation of the aerodynamically induced sound field generated by a blower within a projector. By using this technology, it was possible to locate the sound sources and visualize the sound fields inside the projector, even when the line of sight was completely blocked, and there were impedance discontinuities in the elastic media.

The Significance of Sound Pressure Level (SPL) Values

One of the main benefits of this technology is its ability to quantify and rank source strengths in terms of sound pressure level (SPL) values. This provides a new and effective approach to analyzing noise and vibration issues in complex machines and structures. By quantifying the source strengths, it is possible to prioritize the most significant sources of noise and vibration, providing a more targeted approach to noise control and vibration management.

Revolutionizing Noise and Vibration Analysis

This laser-assisted see-through technology marks a significant stride forward in the field of noise and vibration analysis. By enabling the localization and visualization of sound sources within solid structures, it brings a new level of precision and effectiveness to the analysis of noise and vibration issues. Furthermore, by quantifying source strengths in terms of SPL values, it provides a more effective approach to noise control and vibration management, allowing for targeted solutions that address the most significant sources of noise and vibration.

The Future of Noise and Vibration Analysis

As this technology continues to be developed and refined, it is expected to open the door to a wide range of new applications. From industrial noise control to architectural acoustics, this technology is set to revolutionize the way noise and vibration issues are analyzed and managed. The future of noise and vibration analysis is here, and it is laser-assisted, see-through, and more precise than ever before.
