Accepted Answer

Digital sounds refer to sounds that are recorded and stored using audio signals, which is option B.

Question 3

What does these term refere to:
-Psychoacoustics
A) physical acoustics
B) sound perception
C) acoustics technology
D) none of the above

Accepted Answer

Psychoacoustics is the branch of psychology concerned with the perception of sound and its physiological effects. It studies how humans perceive and interpret sounds, rather than the physical properties of sound itself.

Question 4

What does these term refere to:
-signal ratio
A) editing techniques
B) ratio of signal power to noise power
C) aspect ratio
D) file format ratio

Accepted Answer

Signal ratio, specifically signal-to-noise ratio (SNR), refers to the ratio of the power of a signal (meaningful information) to the power of background noise (unwanted signal).

Question 5

What does these term refere to:
-Perception of sound
A) noise
B) psychoacoustic
C) editing technique
D) special effects

Accepted Answer

Psychoacoustics is the branch of psychology concerned with the perception of sound and its physiological effects. It studies how humans perceive and interpret sounds, including music, speech, and ambient noises.

Question 6

What does these term refere to:
-Frequency
A) property of sound
B) technology of sound
C) ratio of sound
D) none of the above

Accepted Answer

Frequency refers to the number of cycles per second in a wave, which is a property of sound determining its pitch.

Question 7

What does these term refere to:
-sound wave
A) audio pcb
B) propagated through air
C) a software
D) none of the above

Accepted Answer

Sound waves are mechanical waves that are propagated through air (or other media) by the vibration of an object, which causes the air particles to move and transmit the sound.

Question 8

What does these term refere to:
-Analog
A) cassette tapes
B) digital cable
C) integrated chip
D) audio software

Accepted Answer

Analog refers to a way of representing information that uses a continuous range of values, unlike digital which uses discrete values. Cassette tapes are an example of analog technology, where sound is represented by variations in the magnetic field on the tape's surface.

Question 9

What does these term refere to:
-Digital audio
A) magnetic tape
B) audio cassette
C) mp3
D) none of the above

Accepted Answer

Digital audio refers to sound that has been recorded, stored, or manipulated in a digital format. MP3 is a popular digital audio coding format that compresses and encodes audio data.

Question 10

What does these term refere to:
-Science of Sound
A) a sound recording equipment
B) music equipment
C) acoustics
D) none of the above

Accepted Answer

The term "Science of Sound" refers to acoustics, which is the branch of physics concerned with the study of sound waves, their production, transmission, and effects.

Question 11

What does these term refere to:
-Audio Interface
A) capture audio signals from microphones
B) connecting cables
C) console
D) none of the above

Accepted Answer

An audio interface is a device used to capture audio signals from microphones and instruments, converting them into a format that a computer can process.

Question 12

What does these term refere to:
-Ultrasound
A) sound pressure wave
B) speaker
C) woofer
D) none of the above

Accepted Answer

Ultrasound refers to sound pressure waves with a frequency higher than the upper audible limit of human hearing, which is generally considered to be around 20 kHz (20,000 hertz).

Question 13

What does these term refere to:
-Sound Engineering
A) science of audio production
B) technology of hearing equipment
C) science of sound
D) none of the above

Accepted Answer

Sound engineering refers to the science and art of audio production, which involves recording, manipulating, mixing, and reproducing sound.

Question 14

What does these term refere to:
-Condenser Microphone
A) electrostatic
B) digital
C) magnetic
D) none of the above

Accepted Answer

Condenser microphones operate on an electrostatic principle, using a capacitor to convert acoustic energy into an electrical signal.

Question 15

What does these term refere to:
-Dynamic microphone
A) electromagnetic induction
B) digital induction
C) condenser
D) none of the above

Accepted Answer

Dynamic microphones work on the principle of electromagnetic induction, where sound waves cause a diaphragm to move, inducing a current in a coil.

Question 16

What does these term refere to:
-Unidirectional
A) sensitive to only one direction
B) sensitive to all direction
C) sensitive to two direction
D) none of the above

Accepted Answer

Unidirectional refers to being sensitive to or operating in only one direction.

Question 17

What does these term refere to:
-Bidirectional
A) receive sound from one direction
B) receive sound from two direction
C) receive sound from all
D) none of the above direction

Accepted Answer

Bidirectional refers to the ability to receive or transmit sound (or other signals) from two opposite directions.

Question 18

What does these term refere to:
-Omni directional
A) two dimension
B) three dimension
C) single dimension
D) none of the above

Accepted Answer

Omni directional refers to three dimensions, as it can move in all directions.

Question 19

What does these term refere to:
-Cardioids
A) sphere shaped pattern
B) heart shaped pattern
C) square shaped pattern
D) cube shaped pattern

Accepted Answer

Cardioids refer to a heart-shaped pattern, often seen in mathematics as a specific type of curve and in audio technology referring to the directional pattern of microphones.
