Active Noise Control FAQ
Frequently Asked Questions: Active noise control
The FAQ you are now reading discusses active noise control, a novel way of using basic physics to control noise and/or vibration. What is an FAQ, you say? Well, the Internet supports thousands of "newsgroups" -- discussion forums covering every imaginable topic. An FAQ (Frequently Asked Questions list) is a summary written to answer specific questions that arise repeatedly in the newsgroups. This particular FAQ was written for the newsgroups news:alt.sci.physics.acoustics and news:comp.dsp, which focus on acoustics and digital signal processing, respectively. This FAQ has four purposes:
- Provide concise, accurate answers to common questions about active noise control.
- Dispel popular misconceptions about what active noise control can and cannot do.
- Refer interested readers to web links, magazine articles, technical references, and other sources of information.
- Stimulate public interest in acoustics.
