What is a Hydrophone?

07/11/2020

What is a hydrophone? A piezo hydrophone is a kind of underwater microphone designed to monitor underwater noise. A typical peizo hydrophone works by detecting pressure changes in the surrounding environment and converting sound waves into voltage. The speed and distance of the sound wave propagating in the water is proportional to the pressure […]

Geophone in Seismic Survey

07/11/2020

The geophone in seismic survey is the instrument used to transform seismic energy into an electrical voltage. It ordinarily responds to only on the component of the grounds displacement, velocity, or acceleration associated with the passage of a seismic wave. For a seismic reflection survey with P-waves, this is the vertical component. A motion-sensitive […]
