What is the range of the audio spectrum audible to humans?

• 50 Hz to 25,000 Hz

• 100 Hz to 15,000 Hz

• 20 Hz to 20,000 Hz

• 10 Hz to 10,000 Hz

What is the purpose of understanding the audio spectrum in music mixing?

• To increase playback speed

• To optimize sound quality

• To enhance visual effects

• To improve video quality

As humans age, how does the upper limit of hearing typically change?

• Increases to about 25,000 Hz

• Decreases to about 10,000 Hz

• Decreases to about 6,000 to 7,000 Hz

• Remains constant at 20,000 Hz

What effect does aging have on the perception of high frequencies?

• Only affects musicians

• Improves perception

• Reduces perception

• Does not affect perception

What does a waveform visualizer display?

• Both the frequency and amplitude of waves

• Only the frequency of waves

• The musical notes produced by waves

• Only the amplitude of waves

What is the fundamental nature of a sine wave?

• It is a naturally occurring sound

• It is a digital-only sound

• It is the simplest waveform

• It is a complex waveform

What are harmonics in terms of sound waves?

• They are artificial enhancements

• They are imperfections in musical instruments

• They are a series of overtones accompanying the fundamental pitch

• They are disturbances in sound transmission

Why do different instruments playing the same notes sound different?

• All of the above

• Due to the materials they are made from

• Due to the skill of the musician

• Because of the electronic modifications
