Q

Physics of Sound

23
Q

The three major components of acoustics

A
  1. AMBIENT NOISE
  2. REVERBERATION
  3. SIGNAL TO NOISE RADIO (SNR)
24
Q

The percentage of productivity when increased if noise is controlled.

25
Q

It is determined by how fast the sound producing objects vibrates.

26
Q

Basically your ear’s response to the frequency of a sound.

27
Q

The loudness of a wave depends on its energy.

28
Q

Refers to the quality of a person’s voice.

A

TONE OF SOUND

29
Q

The three quantities of characterized sound

A
  1. PITCH
  2. QUALITY
  3. LOUDNESS
30
Q

The frequency of a sound as perceived by human ear.

31
Q

A physiological sensation that depends mainly on sound pressure but also on the spectrum of the harmonics and the physical duration.

32
Q

A wave whose oscillations are perpendicular to the direction of the wave’s advance.

A

TRANSVERSE WAVE

33
Q

The local pressure deviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave.

A

SOUND PRESSURE OR ACOUSTIC PRESSURE

34
Q

The SI unit of sound pressure.

A

PASCAL (Pa)

Q

Used to measure sound level, but it is also widely used in electronics, signals and communication.

A

DECIBEL (dB)

41
Q

A diagram devised by Harvey Fletcher Hudson and W.A. Munson that measures the loudness and softness of a sound as it is heard by a human ear. Also known as the level of human quantity of sound.

A

FLETCHER - MUNSON CONTOURS

42
Q

When two separate sources of sound are perceived simultaneously, the perception of each is made more difficult by the presence of the other.

43
Q

The exact mechanism which the binaural aspect of hearing detects direction is note entirely understood.

A
