Active Noise Cancellation Quiz

How does active noise cancellation (ANC) work?

• By using a microphone to pick up incoming sound waves and creating an anti-noise wave

• By absorbing ambient noise

• By blocking all sound waves from entering the ear cup

• By amplifying incoming sound waves

Which frequencies are more effectively muffled by ANC?

• Higher frequencies

• Mid-range frequencies

• Lower frequencies

• All frequencies equally

What complements ANC in blocking higher frequencies?

• Sound enhancement

• Passive attenuation

• Active amplification

• Noise isolation

What results in a significant decrease in ambient noise levels in headphones like the QC1?

• No noise reduction features

• A combination of active noise cancellation and passive attenuation

• Active noise cancellation only

• Passive attenuation only

What is the main benefit of active noise cancellation in headphones?

• Increased sound distortion

• Reduction in ambient noise levels

• Improved battery life

• Enhanced bass response
