Which of the following is not a possible drawback to having body mics on actors?

• Body mics can pick up costume or other incidental noises.

• Body mics can pick up accidental noises backstage.

• Sound comes from speakers, diminishing the "live" nature of theatre.

• It could make actors too loud.

What does not affect the way sound travels in a room?

• The angle of the walls and ceiling

• The loudness of existing sounds

• The materials used in the room

• The relationship of the lengths of walls to the height of the ceiling

Masking is

• when one sound is obscured by others; lower pitches usually dominate higher pitches

• frequencies that are integral multiples of the fundamental

• the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast

• the quality of a sound given by its overtones

Harmonics are

• when one sound is obscured by others; lower pitches usually dominate higher pitches

• frequencies that are integral multiples of the fundamental

• the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast

• the quality of a sound given by its overtones

Feedback is

• when one sound is obscured by others; lower pitches usually dominate higher pitches

• frequencies that are integral multiples of the fundamental

• the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast

• the quality of a sound given by its overtones

Timbre is

• when one sound is obscured by others; lower pitches usually dominate higher pitches

• frequencies that are integral multiples of the fundamental

• the rumbling, whining, or whistling sound resulting from an broadcast signal that has been returned as input and rebroadcast

• the quality of a sound given by its overtones

The speed of sound in air is 

• 4708 ft/sec

• 3.17 mi/sec

• 3210 mi/hr

• 1129 ft/sec

Amplitude is

• the distance between the crests and/or troughs of a waveform from the neutral line

• the number of occurrences of a repeated event per unit of time

• the intensity of sound

• the distance between repeating units of a wave pattern; the distance from one crest to the next repeated crest

Frequency is

• the distance between the crests and/or troughs of a waveform from the neutral line

• the number of occurrences of a repeated event per unit of time

• the intensity of sound

• the distance between repeating units of a wave pattern; the distance from one crest to the next repeated crest

Loudness is

• the distance between the crests and/or troughs of a waveform from the neutral line

• the number of occurrences of a repeated event per unit of time

• the intensity of sound

• the distance between repeating units of a wave pattern; the distance from one crest to the next repeated crest
