Audio Chapter 1 And 2

Front 1

The Importance of Sound in Production

Back 1

Sound is Omnidirectional; Its is Everywhere

Front 2

Evaluating the Finished Product

Back 2

Monitor loudspeakers is in order. Remember that the sound you evaluate is influenced by the loudspeaker reproducing it ( and the acoustics of the Room)

Front 3

Intelligibility

Back 3

Is a measure of how comprehensible speech is or the degree to which speech can be understood.

Front 4

Tonal Balance

Back 4

Bass Mid range and treble frequencies should be balanced no single octave or range of octaves should out.

Front 5

Definition

Back 5

Each element should be clearly defined-indentifiable separate and distinct.

Front 6

Spatial Balance and Perspective

Back 6

All sonic elements in aural space - stereo or surround sound and should be unambiguously localized: is should be clear where carious sounds are coming from.

Front 7

Dynamic Range

Back 7

The range between the quietest and the loudest sounds that a sound source can produce without distortion.

Front 8

Production values

Back 8

Production values are the most difficult part of an evaluation to define or quantify because response is qualitative and intuitive.

Front 9

Airiness

Back 9

Sound should be open and airy it should not seem isolated stuffy muffled closed-down lifeless overwhelming.

Front 10

Clarity

Back 10

a clear recording is as noise-free and distortion-free as possible hum, hiss, leakage, smearing, blurring, from too much reverberation and distortion-all muddle sound, adversely affecting clarity.

Front 11

Acoustical appropriateness

Back 11

Acoustics the properties of a room that affect the quality of sound, obviously must be good, but they must also be appropriate.

Front 12

Source Quality

Back 12

When a recording is broadcast, downloaded or sent on for mastering there is usually some loss in sound quality.

Front 13

Sound

Back 13

IS produced by vibrations that set into motion radiating waves of compression and rarefaction propagated through a range of media such as gases liquids and solids.

Front 14

Hearing

Back 14

Occurs when these vibrations are received and processed by the ear and sent to the brain by the auditory nerve

Front 15

Sound Waves

Back 15

a vibrational disturbance that involves mechanical motion or molecules transmitting energy from one place to another

Front 16

Elasticity

Back 16

is the phenomenon whereby a displaced molecule tends to pull back to its original position after its initial momentum has caused it to displace nearby molecules.

Front 17

Compression

Back 17

Reducing a signal's output level in relation to its input level to reduce dynamic range. the drawing together of vibrating molecules, producing a high pressure area.

Front 18

Rarefaction

Back 18

Temporary drawing apart of vibration molecules causing a partial vacuum to occur

Front 19

Frequency

Back 19

The number if times per second that a sound source vibrates expressed in hertz (hz) formerly expressed in cycles per second CPS

Front 20

CPS

Back 20

Cycles Per Second

Front 21

HZ

Back 21

Hertz

Front 22

How many CPS in a Hertz

Back 22

1 cycle = 1 Hertz

Front 23

how many hertz in a Kilohertz (khz)

Back 23

10000 Hertz = 10 Kilohertz
