Woody Norris: Hypersonic sound and other inventions

The speaker shares his journey from the Air Force to becoming an inventor, highlighting his creation of a linear tracking tone arm and hypersonic sound technology. He draws an analogy between focusing light and sound, emphasizing the potential applications of hypersonic sound in various industries, including retail and military. The technical aspects of hypersonic sound are explained, showcasing its ability to direct sound precisely. The speaker also discusses other inventions, such as a plasma antenna and Jabber headphones, and concludes with a demonstration of hypersonic sound.

What was the speaker's first invention after leaving the Air Force?

• A digital music player

• A new type of loudspeaker

• A plasma antenna

• A phonograph tone arm

How does the speaker compare the invention of the light bulb to sound technology?

• Both light and sound are equally easy to control

• Sound technology is more advanced than light technology

• Light can be focused, but sound traditionally cannot

• Both have remained unchanged since their invention

What is one potential application of hypersonic sound mentioned by the speaker?

• Highlighting products in a store

• Creating holographic images

• Improving internet speed

• Enhancing video game graphics

According to the speaker, what is a common trait among inventors?

• A formal education

• A willingness to explore new ideas

• A focus on traditional methods

• A preference for working alone

What is the speaker's view on the current state of invention and discovery?

• We are just beginning to explore new possibilities

• Inventions are mostly improvements of old ideas

• Everything has already been invented

• There is little left to discover in science

What is a key characteristic of hypersonic sound technology?

• It is 100% based on non-linearity

• It uses traditional loudspeakers

• It cannot be used underwater

• It is based on linearity

How does hypersonic sound differ from traditional audio systems?

• It is made on the face of the cone

• It is less precise

• It is made in the air along a column

• It requires more power

What is a unique feature of hypersonic sound in terms of sound propagation?

• It follows the inverse square law

• It does not follow the inverse square law

• It is only effective in small spaces

• It requires large speakers

What is one military application of hypersonic sound mentioned?

• Detecting submarines

• Creating fake troop movements

• Encrypting communications

• Guiding missiles

What is the speaker's attitude towards his career as an inventor?

• He regrets not pursuing a different career

• He feels lucky and fulfilled

• He wishes he had more formal education
