What is the primary function of a sound reinforcement system in a concert hall?

  1. To amplify the sound of the performers.

  2. To reduce the reverberation time of the hall.

  3. To create a more immersive listening experience.

  4. To compensate for the acoustics of the hall.

Show answer
Correct Option: D
Explanation:

A sound reinforcement system is used to compensate for the acoustics of a concert hall, which can vary depending on the size, shape, and materials used in the construction of the hall.

Which of the following is NOT a common type of microphone used in a concert hall sound reinforcement system?

  1. Condenser microphone

  2. Dynamic microphone

  3. Ribbon microphone

  4. Lavalier microphone

Show answer
Correct Option: D
Explanation:

Lavalier microphones are typically used for close-miking individual performers, such as singers or instrumentalists, rather than for capturing the overall sound of a concert hall.

What is the purpose of a mixing console in a concert hall sound reinforcement system?

  1. To adjust the levels of the individual microphones.

  2. To apply equalization and effects to the sound.

  3. To route the sound to the appropriate speakers.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

A mixing console is used to adjust the levels of the individual microphones, apply equalization and effects to the sound, and route the sound to the appropriate speakers.

What is the difference between a passive and an active speaker?

  1. Passive speakers require an external amplifier, while active speakers have a built-in amplifier.

  2. Passive speakers are typically smaller than active speakers.

  3. Passive speakers are less expensive than active speakers.

  4. All of the above.

Show answer
Correct Option: A
Explanation:

Passive speakers require an external amplifier to power them, while active speakers have a built-in amplifier that powers the speaker.

What is the purpose of a crossover in a concert hall sound reinforcement system?

  1. To divide the audio signal into different frequency bands.

  2. To route the audio signal to the appropriate speakers.

  3. To adjust the levels of the individual speakers.

  4. All of the above.

Show answer
Correct Option: A
Explanation:

A crossover is used to divide the audio signal into different frequency bands, which are then sent to the appropriate speakers.

What is the term for the time it takes for a sound to travel from the source to the listener?

  1. Reverberation time

  2. Delay time

  3. Propagation time

  4. Transit time

Show answer
Correct Option: C
Explanation:

Propagation time is the time it takes for a sound to travel from the source to the listener.

What is the purpose of a reverberation chamber in a concert hall?

  1. To create a more immersive listening experience.

  2. To reduce the reverberation time of the hall.

  3. To compensate for the acoustics of the hall.

  4. To provide a space for musicians to practice.

Show answer
Correct Option: A
Explanation:

A reverberation chamber is used to create a more immersive listening experience by adding reverberation to the sound.

What is the term for the phenomenon where sound waves bounce off of surfaces and create multiple reflections?

  1. Reverberation

  2. Echo

  3. Flutter echo

  4. Slapback echo

Show answer
Correct Option: A
Explanation:

Reverberation is the phenomenon where sound waves bounce off of surfaces and create multiple reflections.

What is the purpose of a sound diffuser in a concert hall?

  1. To scatter sound waves and reduce reverberation.

  2. To focus sound waves and improve clarity.

  3. To absorb sound waves and reduce noise.

  4. To create a more immersive listening experience.

Show answer
Correct Option: A
Explanation:

A sound diffuser is used to scatter sound waves and reduce reverberation.

What is the term for the frequency range of human hearing?

  1. 20 Hz to 20 kHz

  2. 20 Hz to 16 kHz

  3. 20 Hz to 12 kHz

  4. 20 Hz to 8 kHz

Show answer
Correct Option: A
Explanation:

The frequency range of human hearing is generally considered to be from 20 Hz to 20 kHz.

What is the purpose of a graphic equalizer in a concert hall sound reinforcement system?

  1. To adjust the frequency response of the system.

  2. To apply equalization to the individual microphones.

  3. To route the sound to the appropriate speakers.

  4. To create a more immersive listening experience.

Show answer
Correct Option: A
Explanation:

A graphic equalizer is used to adjust the frequency response of the system.

What is the term for the phenomenon where sound waves cancel each other out?

  1. Interference

  2. Diffraction

  3. Reflection

  4. Absorption

Show answer
Correct Option: A
Explanation:

Interference is the phenomenon where sound waves cancel each other out.

What is the purpose of a delay line in a concert hall sound reinforcement system?

  1. To delay the sound from the main speakers to the rear speakers.

  2. To create a more immersive listening experience.

  3. To compensate for the acoustics of the hall.

  4. To reduce the reverberation time of the hall.

Show answer
Correct Option: A
Explanation:

A delay line is used to delay the sound from the main speakers to the rear speakers, which helps to create a more immersive listening experience.

What is the term for the phenomenon where sound waves are absorbed by a surface?

  1. Absorption

  2. Reflection

  3. Diffraction

  4. Interference

Show answer
Correct Option: A
Explanation:

Absorption is the phenomenon where sound waves are absorbed by a surface.

What is the purpose of a limiter in a concert hall sound reinforcement system?

  1. To prevent the sound level from exceeding a certain threshold.

  2. To apply equalization to the individual microphones.

  3. To route the sound to the appropriate speakers.

  4. To create a more immersive listening experience.

Show answer
Correct Option: A
Explanation:

A limiter is used to prevent the sound level from exceeding a certain threshold.
