1)Sound Wave- A sound wave is a longitudinal pressure wave of audible or inaudible sound caused by a movement of and object.

2)Frequency- Frequency is the number of occurrences of a repeating event per unit time.

3)Pitch- Pitch represents the perceived fundamental frequency of a sound.It is one of the three major auditory attributes of sounds along with loudness and timbre.

4)Amplitude- Amplitude is the magnitude of change in the oscillating variable, with each oscillation, within an oscillating system. For instance, sound waves are oscillations in atmospheric pressure and their amplitudes are proportional to the change in pressure during one oscillation.

5)Loudness- Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude).

6)Wavelength- In physics, the wavelength of a sinusoidal wave is the spatial period of the wave and sound on the distance over which the wave’s shape repeats.

7)Acoustical Phase- Sound that comes out from a string instruments, such as guitars and other instruments that involve strings.

8)Sound Envelope- Sound envelopes are sound packages extracted from video files. Video editing tools, such as the freeware program Zwei-Stein, isolate the audio portion of the avi, mpeg (whatever clip) and “envelope” it for podcast or other distribution.

9)Velocity- In physics, velocity is the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it.

10)Timbre-In music, timbre is the quality of a musical note or sound or tone that distinguishes different types of sound production, such as voices or musical instruments.

1) a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
2) when a vibration passes through one complete up-and-down motion,from compression through rarefaction,it has completed one cycle. the number of cycles that a vibration completes in one second in expressed as its frequency.
3) the relative tonal highness or lowness of a sound. the more times per second a sound source vibrates the higher its pitch.
4) our subjective impression of amplitude is a sound’s loudness or softness. amplitude is measured in decibels.
5) all increase in loudness throughout the midrange. reducing loudness at 5,000 Hz make a sound seem transparent and farther away.
6) determined by the distance a sound wave travels to complete one cycle of compression and rarefaction; that is, the physical measurement of the length of one cycle is equal to the velocity of sound divided by the frequency of sound.
7) refers to the time relationship between two or more sound waves at a given point in their cycles.
8) has four stages: attack,initial decay, sustain, and release(ADSR). attack is how a sound starts after a sound source has been vibrated.
9) or the seed of sound waves-should be mentioned. velocity usually has little impact on pitch or loudness and is relatively.
10) the sound frequency spectrum is an objective scale of relative pitches; the table of sound-pressure levels is an objective scale of relative loudness.

1) Sound Wave-a vibrational disturbance that involves mechanical motion of molecules transmitting energy from one place to another.
2)Frequency- the # of times per second that a sound source vibrates.
3)pitch-the subjective perception of frequency
4)amplitude-the magnitude of a sound wave or electric signal measured in decibels.
5)loudness-sounds have different levels and we don’t hear the same loudness level the same.we hear the middle frequencies and that is called equal loudness principal.
6)wavelength-the length of one cycle of a sound the higher the frequency the shorter the wavelength.
7Acoustical Phase-the time relationship between two or more sound waves at a given point in their cycles.
8)Sound Envelope-changes in the loudness of a sound over time.
9)Velocity-the speed of a sound wave.
10)Timbre-the unique one quality or color of a sound

1. The sound wave- A vibrational disturbance that involves mechanical motion of molecules transmitting energy from one place to another
2.Frequency- The number of times per seconds that a sound source vibrates. Now expressed in hertz (Hz);formerly expresses in cycles per second (cps).
3.Pitch-The subjective perception of frequency.
4.Amplitude-The magnitude of a sound wave or electric signal measured in decibels.
5.Loudness-the number of molecules moving, also the wave sound size
6.Wavelength-The length of one cycle of a sound wave. Wavelength is inversely proportional to the frequency of a sound; the higher the frequency, the shorter the wave length.
7.Acoustical Phase-The time relationship between two or more sounds waves at a given point in their cycle.
8.Sound Envelope-Changes in the loudness of a sound over time , described as occurring in four stages:attack, initial decay, sustain and release.
9.Velocity- The speed of a sound wave: 1,130 feet per second at sea level and 70f
10.Timbre-The unique tone quality or color of a sound.

FREQUENCY: is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency.

PITCH:the relative tonal highness or lowness of a sound.

AMPLITUDE: is the magnitude of change in the oscillating variable, with each oscillation, within an oscillating system

LOUDNESS: They were the first Japanese heavy metal act signed in the United States, releasing seven albums by the end of 1987 and reaching the Billboard top.
WAVELENGTH:Of a sinusoidal wave is the spatial period of the wave the distance over which the wave’s shape repeats

ACOUSTICAL PHASE:the time relationship between two or more sound waves at a given point in their cycles.

SOUND ENVELOPE: changes in the loudness of a sound over time described as occurring in four stages.

VELOCITY:the speed of a sound wave 1,130 feet per second at sea level and 70f

TIMBRE:In music, timbre pronounced ˈtæmbər like tahmber or spelling pronunciation bərFrenchis the quality of a musical note or sound or tone that distinguishes different types of sound production such as voices or musical instruments.

1. Sound Wave: Waves that result when stone is dropped into a pool.
2. Frequency: The number of times per seconds that a sound source vibrates.
3. Pitch: Its the subjective perception of frequency.
4. amplitude: It is the magnitude of a sound wave or electric signal measured in decibels.
5. Loudness: Noise is loud, the level of sound is very high and it can be easily heard. Someone or something that is loud produces a lot of noise.
6. Velocity: The speed of a sound wave.
7. Wavelength: The length of one cycle of a sound wave. Wavelength is inversely proportional to the frequency of a sound; the higher the frequency the shorter the wavelength.
8. Acoustial Phase: Time a relationship between two or more sound waves at a given point in their cycles.
9. Timbre: The unique tone quality or color of a sound.
10. Sound Envolope: Sound packages extracted from video files.
