Sound waves are vibrations that travel through a medium, such as air, to be received and perceived by the brain. Other words for sound waves include acoustic waves, longitudinal waves, compression waves, and transverse waves.
1. A source 2. Elastic medium (air) 3. A receiver
If we deal with a modern digital telephone, this is what happens. 1) When you speak you cause vibrations (sound) in the air. 2) These vibrations move a magnet in an coil found in the telephones microphone. 3) This movement of the microphone generates electricity. 4) The electrical oscillations are converted into numbers which describe them via an analogue to digital converter. 5) The number stream is sent over the telephone wire or (carrier wave with a cell phone) through all the exchanges to the telephone you are calling. 6) In the receiving telephone the number stream is converted back into electrical oscillations by an digital to analogue converter. 7) The electrical oscillations are fed into a coil in which sits a magnet (and cone)- called the speaker. 8) The magnet moves in response to the electricity in the coil and causes the cone to vibrate the air. 9) The person on the phone hears the vibrations in their ear as sound.

Sound is basically the physiological sensation received by the ear. It is cause due to vibrations.
Because the particles are far closer together, and so the vibrations received from neighbouring particles will be greater, thus enabling a strong conduction rate!

ocean mapping is made possible through indirect methods. Oceanographers use echo sounding, sonar, radar, and seismographic surveys. Vibrations such as sounds are set down from the ocean surface. The vibrations are then reflected from the ocean bottom at the same angle that they are received and are recorded at the surface. To calculate the distance to the bottom, the following equation is used d= 1/2 t x v
There are three processes of listening: as you see someone and they exclaim your name, the sound that they make set off your eardrums, making the three small bones vibrate. The vibrations then travel into your auditory nerve, and the movement of their lips are received by your optical nerve.
