sound gets to your ears by vibrations in the air. the radio sends the vibrations out of the speaker causing the air to vibrate, when the sound reaches the ear drum it makes it vibrate, allowing us to hear sound. Kieran Cash 15 years old :)

A microphone has a diaphragm that vibrates with the changes in air pressure, caused by sound. This is attached to a coil and a magnet generating varying electrical signal. This is then amplified.
The audio signal is applied to a radio frequency generator and coded, depending on what system is in use. Either Amplitude modulated or Frequency modulated. The audio can shift the strength of the radio signal, in time with the audio or shift the frequency of the radio frequency in time with the audio.
RECEIVER
A tuned system of coil and capacitor is made to resonate at the frequency of the radio signal (tuned).
The signal is amplified.
The radio frequency part is removed by a filter.
This leaves just the original audio signal, this amplified again.
The powerful audio electrical signal is applied to a loudspeaker (which works like a microphone in reverse.
This causes a diaphragm (cone) to move and cause air pressure changes. This is perceived as sound by your ear.

Why is the ear shaped the way it is?
The visible portion of the ear is shaped in such a way that it best amplifies sound. A pig's ear is large and concave so that it can trap sound waves and amplify them inside the pig's ear for optimum hearing.
What is the maximum sound limit bared by human ears maxximum sound limit which can be bared by human ears?
If you mean loudest possible, that would be 194dB. If you mean loudest before the tissue of the human ear dies instantly, that would be 180dB.
When people hear a sound their ears turn the vibrations in the air into neural messages from the auditory nerve which makes it possible for the brain to interpret the sound This process is called?
Encoding
What is the purpose of an ear?
The primary function of the ears is to allow us to hear sounds. In order to hear a sound, the ears are equipped with small parts known as the "drum". What happens is when a sound finds its way into our ears, the drumb and other hairs pick up vibrations (or soundwaves), which produce a sound registration in our brains.
How do sound waves reach your ears?
The path that it undergoes is:1.Eardrum,2.Ear Bones,3.Cochlea,4.Auditory Nerve.+++Yes, that's the anatomy but not the answer to that question, which actually almost answers itself. Sound is a series of pressure-waves travelling through the air (or water).
Is a radio a sound energy?
A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.
How you hear sound?
In our ears the sound vibrates and makes the sound
Why do rabbets keep turning their big sound collecting ears?

Can a chicken hear sound?
they can hear sound in ears
What happens when sound reaches your ears?
you can hear A very complicated process of turning waves into sound occurs in your ears
Do animals urinate from their ears?
No they don't; ears are for hearing sound and not for urinating.
Which energy can be sensed by the ears in science?
The ears sense sound energy.
How do buffalo sense sound?
With Their Ears.

ears
What do ears convert?
Sound waves.
How do animals hear sound?
