Noise Pollution Control Technologies
Noise pollution is a major environmental problem that can have a negative impact on human health and well-being. Noise pollution control technologies are designed to reduce or eliminate noise pollution.

What is the difference between active and passive noise control technologies?
- Active noise control uses sound waves to cancel out unwanted noise, while passive noise control uses materials and structures to block or absorb sound waves.
- Active noise control uses materials and structures to block or absorb sound waves, while passive noise control uses sound waves to cancel out unwanted noise.
- Both active and passive noise control technologies use sound waves to cancel out unwanted noise.
- Both active and passive noise control technologies use materials and structures to block or absorb sound waves.
Which of the following is an example of an active noise control technology?
- Soundproofing
- Noise barriers

How do active noise control systems work?
- By generating sound waves that are equal in amplitude but opposite in phase to the unwanted noise
- By generating sound waves that are equal in amplitude and in phase with the unwanted noise
- By generating sound waves that are louder than the unwanted noise
- By generating sound waves that are softer than the unwanted noise
