1. A source 2. Elastic medium (air) 3. A receiver
First, something must vibrate. Second, you need something through which the vibrations, or sound waves, can travel. Third, these traveling vibrations must be received somehow.
A transmitter, a medium thru which to travel, and a receiver.
1.A Source:A body having particles that can vibrate.
2.A Medium:An elastic medium for the propagation of sound.
3.A receiver.
Sound cannot be transmitted in a vacuum.
Medium and electricity
The voice mechanism consists of three main parts: the lungs, which provide air for sound production, the vocal cords, which vibrate to produce sound, and the resonating chambers in the throat, mouth, and nose, which shape and amplify the sound.
To produce laser light, three conditions are necessary: a gain medium to amplify the light, an energy source to excite the atoms in the gain medium, and an optical resonator to select and amplify the light through stimulated emission. These conditions allow for the emission of a coherent and collimated beam of light with a narrow wavelength range.
Three characteristics of sound are pitch (frequency of vibrations), volume (amplitude of vibrations), and timbre (quality of sound).
In order to hear a sound, three things are needed: a source of sound producing vibrations, a medium such as air or water for the vibrations to travel through, and the ear to receive and interpret the vibrations as sound.
Three factors that affect the speed of sound in water are temperature, salinity, and pressure. Generally, sound travels faster in warmer water, at higher pressures, and in water with higher salinity.
There are three components in the production of sound. The first thing you need is a physical object that is vibrating, because vibrations create sound. The next thing you need is a medium to carry out the vibrations. The last necessary piece in the production of sound is an ear to hear the sound and turn it into something meaningful. These three things are as simple as a person playing an instrument to a crowd.

The three conditions necessary for causation between variables are covariance (relationship between variables), temporal precedence (the cause must precede the effect in time), and elimination of plausible alternative explanations (other possible causes are ruled out).
For demand to exist you have to want a good. You have to be able to afford the good. And you have to have a definite plan to buy the good.
when necessary, these bones can reduce sound intensity to the inner ear
It is just left of Sound Stage 4, which is down in the lower right corner of the studio lot. From Sound Stage 1, Sound Stage 2 is 2 blocks to the right. From Sound Stage 1, Sound Stage 3 is three blocks down. From Sound Stage 1, Sound Stage 4 is 4 blocks down and 3 blocks right. From Sound Stage 1, Post Production is 4 blocks down and 2 blocks right.
A beneficial mutation leading to variability in a population and the heritability of those beneficial traits.
The Production Budget for Three Kings was $48,000,000.
The Production Budget for Three to Tango was $20,000,000.
In chess, in order for a check to be a checkmate, there are three specific conditions: 1) The king must not be able to move out of check. 2) The attacking piece must not be capture-able. 3) No pieces must be able to block the check.

The three necessary conditions to be candidate for United States President are as follows: 1) He must be a natural-born citizen 2) He must be over the age of 35 years. 3) He must have been an inhabitant the United States for no less than 14 years.
