Main Points To Remember

1. Sound design is the process of creating the overall sonic character of a production and is ongoing throughout the production process.

2. The sound designer is responsible for creative control of the audio–to put a coherent sonic stamp on a production–although all members of the audio team make creative contributions to the sound.

3. There are three domains to work with in creating a sound design: speech, sound effects, and music. Paradoxically, silence and the ability of sound to evoke a picture in the mind’s eye may be considered two other domains.

4. All sound is made up of the same basic components: pitch, loudness, timbre, tempo, rhythm, attack, duration, and decay.

5. Sound also has a visual component in that it can create pictures in the “theater of the mind.”

6. Sound has several functions in relation to picture; Sound can parallel picture, sound can define picture, picture can define sound and picture can define effect, and sound can counterpoint picture.

7. There  is no set procedure for designing sound. At the outset the most important thing to do is study the script and analyze the auditory requirements line by line to determine the overall sonic approach to various scenes or for an entire work, or both.

8. Determining a sound design involves consideration of how the audience is to think or feel about a particular story, scene, character, or action; from what point of view; and whether that is to be carried out mainly in the sound effects or music or both.

9. Determining a sound design also requires the awareness that doing so is often tantamount to defining a production’s conceptual and emotional intent.

Main Points To Remember

1. A sound wave is a vibrational disturbance the involves mechanical motion of molecules transmitting energy from one place to another.

2. A sound wave is caused when a body vibrates and sets into motion the molecules nearest to it; the initial motion the molecules nearest to it; the initial motion starts a chain reaction. This chain reaction creates pressure waves through the air, which are perceived as sound when they reach the ear and brain.

3. The pressure wave compresses molecules as it moves outward, increasing pressure, and pulls the molecules farther apart as it moves inward, creating a rarefaction by decreasing pressure.

4. The components that make up a sound wave are frequency, amplitude, velocity, wavelength, and phase.

5. Sound acts according to physical principles, but it also has a psychological effect on humans.

6. The number of times a sound wave vibrates determines its frequency, or pitch. Humans can hear frequencies between roughly 20 and 20,000 HZ–A RANGE OF 10 octaves. Each octave has a unique sound in the frequency spectrum.

7. The size of a sound wave determines its amplitude, or loudness. Loudness is measured in decibels.

8. The decibel (db) is a dimensionless unit used to compare the ratio of two quantities usually in relation to acoustic energy, such as sound-pressure level (SPL), and electric energy, such as power–dBm–and voltage, such as dBv) and dBV.

9. Impedance is that property of a circuit, or an element, that restricts the flow of alternating current (AC). Impedance is measured in ohms, a unit of resistance of current flow.

10. Humans can hear from 0 dB-SPL, the threshold of hearing to 120 dB-SPL, the threshold of feeling; to 140 dB-SPL, the threshold of pain, and beyond. The scale is logarithmic, which means that adding two sounds each with a loudness of 100 dB-SPL, would bring it to 103 dB-SPL. The range of difference in decibels between the loudest and quietest sound a vibrating object makes is called dynamic range.

11. The ear does not perceive all frequencies at the same time loudness even if their amplitudes are the same. This is the equal loudness principle. Humans do not hear lower-and higher-pitched sounds as well as they hear midrange sounds.

12. Masking–covering a weaker sound with a stronger sound when each is a different frequency and both vibrate simultaneously–is another perceptual response dependent on the relationship between frequency and loudness.

13. Velocity, the speed of a sound wave, is 1,130 feet per second at sea level and 70 degrees F. Sound increases or decreases in velocity by 1.1 feet per second for each change of 1 degree F.

14.  Each frequency has a wavelength, determined by the distance a sound wave travels to complete one cycle of compression and rarefaction. The length of one cycle is equal to the velocity of sound divided by the frequency of sound. The lower a sound’s frequency, the longer its wavelength; the higher a sound’s frequency, the shorter its wavelength.

15. Acoustical phase refers to the time relationship between two or more sound waves at a given point in their cycles. If two waves begin their excursions ate the same time, their degree intervals will coincide and the waves will be in phase. If two waves begin their excursions at different times, their degree intervals will not coincide and their waves will be out of phase, weakening each other and decreasing amplitude.

16. Timbre is the tone quality, or tone color, of a sound.

17. A sounds envelope refers to its changes in loudness over time. It has four stages: attack, initial decay, sustain, and release (ADSR).
