By listening to the sound of groundwater flowing, a groundwater path (place where groundwater concentrates) that was difficult to find previously can now be detected easily.

Overview

Under the ground, various sounds (noises) exist such as the sound of groundwater flowing, sound of friction of sand and stone, sound of wind, sound of insect movement, etc.
A groundwater aeration sound measuring device enables the groundwater flowing sound (groundwater aeration sound) to be detected by reducing various underground noises by means of a noise cut filter and sound volume adjusting functions. By looking for a place where this sound has the greatest intensity, a groundwater path where groundwater concentrates is identified.

Features

1. The position of the groundwater path can be distinguished instantly.
2. Anyone can make measurement with the same accuracy.
3. A highly sensitive sensor is adopted that enables even an ant's footfalls to be detected.
4. The equipment can be carried and used for measurement by one person due to its small size and light weight (approx.1.4 kg).
