Understanding Sound Representation in Digital Tech

What is the unit of frequency used to measure sound waves?

• Decibels

• Hertz

• Metres

• Watts

Which of the following best describes the term 'bit depth' in digital sound?

• The number of sound channels

• The number of bits used to represent each sample

• The frequency of the sound wave

• The duration of the sound

What is the typical bit depth used in CD-quality audio?

• 8 bits

• 16 bits

• 24 bits

• 32 bits

Which of the following is a common sample rate for digital audio?

• 8 kHz

• 44.1 kHz

• 96 kHz

• 192 kHz

What does the term 'sampling rate' refer to in digital sound?

• The number of bits per sample

• The number of samples taken per second

• The amplitude of the sound wave

• The length of the audio file

How does increasing the bit depth affect the quality of digital audio?

• It decreases the file size

• It increases the dynamic range

• It reduces the frequency

• It shortens the duration

What is the effect of increasing the sampling rate in digital audio?

• It increases the file size

• It decreases the bit depth

• It reduces the dynamic range

• It shortens the audio duration

What is the primary advantage of using a higher bit depth in digital audio?

• Increased file size

• Improved sound quality

• Reduced sampling rate

• Shorter audio duration

How does increasing the sampling rate affect the frequency range of digital audio?

• It decreases the frequency range

• It increases the file size

• It has no effect on the frequency range

• It reduces the bit depth
