What does a hydrophone measure?
When submerged in the ocean, a ceramic hydrophone produces small-voltage signals over a wide range of frequencies as it is exposed to underwater sounds emanating from any direction. By amplifying and recording these electrical signals, hydrophones measure ocean sounds with great precision.
What is a hydrophone in ultrasound?
A hydrophone is an ultra-compact, receive-only transducer that is specially designed for measuring underwater ultrasound acoustic fields. It has a high resolution and is capable of measuring a wide range of frequencies.It uses Toray's unique P (VDF-TrFE) polymer piezoelectric material.
