21
Q

A scientist who works in the field of acoustics is an

A

acoustician

22
Q

Sound Localization

A

a listener’s ability to identify the location or origin of a detected sound

23
Q

Binaural Localization

A

relies on the comparison of auditory input. from two separate detectors. Explains the cocking the head to one side when trying to locate a sound

24
Q

Live materials have high _____

A

reflectivity i.e. glass, stone, metal

25
Q

Dead materials have ______

A

absorption i.e. carpeting, drapery

26
Q

Reverbration

A

the persistence of sound after its source has stopped, caused by multiple reflections of the sound within a closed space

27
Q

Diffraction

A

lower frequencies of sound waves

28
Q

Diffusion

A

halfway point between absorption and refraction

29
Q

Precedence Effect

A

if you hear a direct sound, your brain is gonna turn off the other elements so you can be more accurate in finding where the sound is

30
Q

Differences between candy & scoring room

A
  • Candy Room has completely dead walls, but scoring stage is large and live. Candy room is better to record loud things
  • Candy room does not have a machine room, but does have silent amplifiers and a quiet Mac Pro computer to offset
  • Scoring stage has a window which makes communication with the talent easier
  • Candy room has the MIDI keyboards in the same room as the engineer, which can make recording easier
31
Q

Studio Glass

A

3/8-3/4 inch thick glass, one window panel must be tilted at a 5 degree or more angle to the other to eliminate standing waves within the sandwiched airspace

32
Q

Doors in a studio

A

should be constructed of solid wood or high quality acoustical materials, should be double doored when possible to reduce leakage

33
Q

Transmission Loss (TL) is

A

the amount of sound-pressure level (SPL) transmission in dB that was lost as the sound passed through the barrier

34
Q

To reduce leakage means

A

to increase transmission loss, which increases as frequency rises

35
Q

Constructions with opposing parallel walls give rise to a nasty phenomenon known as

A

standing waves

36
Q

Standing waves

A

occur when. sound is reflected off parallel surfaces and travel back upon its own path

37
Q

Three main applications for EQ

A
  1. problem solving
  2. emphasizing or de-emphasizing an instrument in a mix
  3. altering a sound’s personality
38
Q

Purpose of an EQ notch

A

to remove an undesirable sound

39
Q

90% of the song is the _____

A

sustain

40
Q

The job of a compressor is ______

A

to increase the perception of the sustain, NOT to make it louder

41
Q

Phantom power is

A

a method to send DC electrical voltage through microphone cables. It places the same direct current voltage on both signal lines of a balanced audio connector. The +48 volts DC is piggybacked on top of both AC signals via two resistors without disturbance.

42
Q

A microphone is a

A

transducer

43
Q

Three responsibilities of the engineer

A
  1. Place the musicians in the desired studio positions
  2. Choose and place the microphones
  3. Records the performance onto disk or tape
44
Q

A bass rolloff switch is

A

a low frequency filter that can help reduce unwanted background noise

45
Q

Perfect phase coherence

A

if two waves are exactly the same and played in perfect sync, the result is common amplification. This is called constructive interference

46
Q

Timbre

A

timbre is the unique characteristic sound of a music instrument

47
Q

Doppler Effect

A

the change in frequency and wavelength of a wave as percieved by an observer moving relative to the source of the waves. A sounds pitch is higher as the sound source approaches you, and lower as it recedes

48
Q

XLR

A

X = cannon, L = Latch, R = Rubber

49
Q

TT cable

A

tiny telephone

50
Q

Most important button in Pro Tools

A
