• The first non-stop flight around the world in the Voyager aircraft

• The first moon landing

• The invention of the first personal computer

How does passive noise cancellation primarily work?

• By amplifying ambient noise

• By using electronic signals to cancel sound

• By using wireless signals to block sound

• By physically blocking sound waves with materials

What is the main challenge of active noise-canceling technology?

• It requires constant battery replacement

• It is too expensive for consumers

• It struggles with high-frequency sounds

What is the 'noise floor' in active noise-canceling headphones?

• The sound of the headphones turning on

• The electronic hiss produced by the circuitry

• The ambient noise from the environment

• The sound of the user's heartbeat

How might future noise-canceling technology improve according to the video?

• By using larger headphones
