Web29 aug. 2004 · The human ear operates by sensing pressure variations above and below atmospheric pressure. A sound wave entering the ear canal exerts a fluctuating pressure on one side of the eardrum; the air on the other side of the eardrum is at atmospheric pressure. The pressure difference on the two sides of the eardrum sets it into motion. WebPhysics is a branch of science.It is one of the most fundamental scientific disciplines.The main goal of physics is to explain how things move in space and time and understand how the universe behaves. It studies matter, forces and their effects.. The word physics comes from the Greek word ἡ φύσις, meaning "nature". Physics can also be defined as "that …

WebWhat Is Sound. In physiology, sound is produced when an object’s vibrations move through a medium until they enter the human eardrum. In physics, sound is produced in the form of a pressure wave. When an object vibrates, it causes the surrounding air molecules to vibrate, initiating a chain reaction of sound wave vibrations throughout the medium.

"WebVolume. The volume of sound is the measure of loudness. To quantify volume we use decibels. The more decibels, the louder the sound is. A soft sound, like a whisper will measure around 15-20 decibels. A loud sound like a jet engine is more like 150 decibels. The threshold of pain occurs at around 130 decibels.
