Is it maybe that the guitars are being played simultaneously? If your question is what it is than there is a lot of room for player interpretation while playing the same notes on a guitar or any other instrument. Also there is no such thing as "identical" guitars, every guitar sounds a little different due to age, usage, small construction differences, etc.

Air temperature, air pressure have impact too. If we look at this from a cold, science point of view, heres what it would look like. If you put 2 identical guitars played by a robot into a studio, they would sound the same. Except they wouldn't, for the reasons above. Just to give you an example of what might be relevant here, here's a "phase shift" example:. If the shift would be larger, lets say half a second - you would hear a significantly stronger echo effect.

Ya, phase difference is a point, but it will not effect the quality of the sound produced. Consider the two guitar players in two different rooms, none can hear the other one. In such a case the quality of the note will be same. We love our teachers, and so will you. Teach or Tutor for Us. The Princeton Review is not affiliated with Princeton University.

In constructing sound, there must be a source for a sound. The source of a sound wave is vibrating object. A disturbance that travels or propagates through space and time, usually by transference of energy is known as a Wave. A wave is a disturbance by which energy is transferred. A wave which causes disturbance in the direction of its propagation is known as a longitudinal wave, whereas a wave which causes disturbance perpendicular to the direction of its propagation is known as a transverse wave.

Sound waves are the one of the most important examples of longitudinal waves. Loudness and pitch are two aspects of any sound and each refers to a sensation in the consciousness of the listener. The lower the frequency, the lower is the pitch and the higher the frequency, the higher is the pitch. For an example, a bird makes a high pitch besides a lion makes a low pitch. Sensitivity of the human ear is around 20 Hz to 20 Hz. They can generate by musical instruments, human vocal cords and loudspeakers.

It is also the distance the wave travels before the pattern repeats itself and is measured in metres m. It is measured in seconds s. Frequency is the number of oscillations per unit time at any point and is measured in hertz Hz. Displacement x is the distance any part of the wave has moved from its mean position. It is always positive and is measured in metres m.

The propagation of a sound wave is due to the movement of air particles. Regions of high pressure are known as compressions and regions of low pressure are known as rarefactions. In the diagram, the black dots represent air molecules. As the loudspeaker vibrates, it causes the surrounding air molecules to vibrate in a particular pattern represented by the waveform. This vibration of air molecules causes the listener's eardrum to vibrate in the same pattern and it results in sound.

Sound waves exist as variations of pressure in a medium like air. The energy is transferred from the source in form of longitudinal sound waves and the sound is detected by an ear or an instrument. Sound waves travel through any material medium with a speed that depends on the properties of the medium. Sound cannot travel in the absence of a medium. The speed of sound waves depends on the compressibility and the inertial property of the medium.

As the waves travel, the particles in the medium vibrate to produce density and pressure changes along the direction of motion of the wave. These changes result in a series of high pressure and low pressure regions.

Sound homework help September 11, Uncategorized 0 For my writing folio i'm doing essays on my coming out story for personal and gay marriage or . Every kind of sound is produced by vibration. The sound source may be a violin, an automobile horn, or a barking dog. Whatever it is, some part of it is vibrating while it is producing sound. The vibrations from the source disturb the air in such a way that sound waves are produced. These waves travel out in all directions, expanding in balloonlike fashion from the source of the sound.
