Through the creation of electrical energy which travels though through an elastic medium

Through the displacement of an elastic medium

Through the creation of mechanical energy that breaks down an elastic medium

Through the displacement of a mechanical medium

a) When there is a reduction in pressure at a point in the elastic medium b) When there is an increase in pressure at a point in the elastic medium

a) When there is an increase in pressure at a point in the elastic medium b) When there is a decrease in pressure at a point in the elastic medium

a) When there is no pressure change at a point in the elastic medium b) When there is a decrease in pressure at a point in the elastic menium

a) When there is an increase in pressure at a point in the elastic medium b) When there is no pressure change at a point in the elastic medium

It's propagated along a wave of mechanical energy until it is funneled into the ear by the pinnae

It is propagated along a wave of neural energy until it is funneled into the ear by the pinnae

It is propagated along a wave of neural energy until it makes contact with the pinnae resulting in an action potential

It is propagated along a wave of mechanical energy until it makes contact with the pinnae resulting in an action potential

When there is carbon dioxide present to fuel the energy

When there is an elastic medium present such as in water or in a vacuum

In a vacuum only

When there is en elastic medium present
