The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, and skydivers use wrist-mounted versions for similar ...

Pilots can use a "cabin altimeter" (also known as a cabin differential pressure gauge) to measure the difference between inside and outside pressure. [ 8 ] Keeping the cabin altitude below 8,000 ft (2,438 m) generally prevents significant hypoxia , altitude sickness , decompression sickness , and barotrauma . [ 9 ]
Your ears are responsible for more than just hearing; they keep you balanced, control facial features and help your taste, thanks to what's inside.
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates , the inner ear is mainly responsible for sound detection and balance. [ 1 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
There’s a lot more going on inside your ears than first meets the eye. The ears are arguably one of the most important features of the human body. They allow us to hear the world around us every ...
The Black Hawk helicopter may have been flying with “bad data” and didn’t hear all air traffic control instructions before colliding with a passenger plane, officials said.
3D model of cochlea and semicircular canals. The cochlea is the part of the inner ear involved in hearing.It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus.
