REVISION PAPER 4

The term frequency refers to how fast or slow a wave cycles. This term is applied to:

• Electrical signals through sound equipment

• Both

• Sound waves through air

With a sine wave, the frequency is measured by:

• Both

• How often a cycle repeats

• The amplitude of the signal

Hertz measures:

• The number of cycles per second

• The number of cycles per millisecond

• The number of cycles per minute

Normal hearing range is approximately:

• 20 Hz to 10000 Hz

• 20 Hz to 30000 Hz

• 20 Hz to 20000 Hz

The middle of human hearing is around:

• 500 Hz

• 5000 Hz

• 1000 Hz

5,000 Hz is the same as:

• Both

• Five kHz

• 5k

Typically within professional audio, we divide frequency bands into categories. Which is correct?

• Only Lows

• Only Highs

• Only Mids

• Highs, Mids, Lows

A person with excellent hearing can hear all the frequencies around us being transmitted, even radio frequencies.

• True

• False

Mixing live sound involves:

• Keeping a balance across the frequency range of human hearing

• Patching the dimmer rack

• Avoiding the use of dynamics

• Avoiding the use of EQ

Phase is the relationship between

• a microphone and the stand

• two or more audio signals

• a microphone and the console

• a DI box and a microphone
