An electroacoustical transducing system for exchanging pressure wave energy with a medium that propagates pressure waves includes an electroacoustical transducer having a vibratile surface. At least one low-loss pressure waveguide has one end adjacent to the vibratile surface and the other end adjacent to the medium.

Hydrocephalus shunts and waves of intracranial pressure
Medical & Biological Engineering & Computing, 2005The majority of contemporary hydrocephalus valves are designed to introduce a low resistance to flow into the cerebrospinal fluid (CSF) drainage pathway, and an therefore intended to stabilise intracranial pressure (ICP) at a level close to the shunt's operating pressure. However, this goal cannot always be attained.

PRESSURE WAVE VELOCITY IN THE HUMAN AORTA*
Journal of the American Geriatrics Society, 1968A bstract After introduction of a catheter into the aorta, the pressure wave velocity was measured in 26 subjects whose ages ranged from 9 to 68 years. The first site of registration was approximately 10 cm from the aortic valve, and the second was 50 cm ...

Gas and liquid are termed fluid because they can flow with changes to their shape. Most flows occurring in our daily life are not significantly influenced by compressibility. However, in high-speed flows and/or when velocity or pressure rapidly varies, compressibility is significant.

Bending waves and pressure waves in solid rods.
The Journal of the Acoustical Society of America, 2009Dimensionally identical aluminum rods are excited by a hammer impulse. One rod is suspended by rubber bands at a distance of nearly 1/4 of the length of the rod near the rod’s ends. The rod is excited near the end in a direction perpendicular to the rod axis. The other rod is supported by a clamp at the middle of the rod.
