"Acoustic Tomography Ground Exploration" [Visualizing the Underground Cross-Section!]

Visualizing underground cross-sections using sound waves as if captured by a camera! A ground exploration technology capable of surveying urban areas!

"Acoustic Tomography Ground Exploration" is a technology that visualizes underground cross-sections as if captured by a camera, utilizing the characteristics of sound waves that propagate through the ground. It emits vertical waves with controlled frequency and amplitude from a transmitter installed in a borehole, and receives the sound waves that have propagated underground with a receiver. By analyzing the data obtained on-site, information about velocity and attenuation rates can be acquired. [Features] ■ High precision and wide-ranging investigation possible ■ Two types of information can be obtained ■ Suitable for investigations in urban areas *For more details, please request materials or view the PDF data from the download section.
