Audio questions

I finished my audio questions and illustrations/diagrams today.

1. What range of frequencies are detectable to the human ear?


20Hz(lowest)-20kHz(highest)

2. Define Audio

Audio is the range of frequencies detectable by the human ear.

3. Audio production involves what four elements of audio?

Audio is the production, recording, manipulation and reproduction of sound waves.

4. List 10 careers in audio and list a local company for six of the career fields

Studio Sound engineer, Live sound engineer, Musician, Music producer, DJ, Radio technician, Film/Television Sound Recording, Field Sound Engineer, Audio Editor, Post-Production Audio Creator

5. List three careers that need to have an understanding of audio production concepts

Video Camera operators, Film, and Video

6. A person rings a bell and another person hears the sound. Draw a diagram (in your composition book) of how this sound is created, transmitted, and received by a human

7. What is a waveform

The form of a wave on a graph.

8. Is sound two dimensional or three dimensional?

Three dimensional.

9. How do variations in sound pressure correlate to a waveform diagram?

High values represent areas of increased pressure, when the wave hits a low point the molecules are spread more thinly.

10. Illustrate (in your composition book) the difference between wavelength, amplitude, and frequency.

11. Diagram (in your composition book) in phase, 180deg out of phase, and different wave and how they interact.

12. Define transducer

A device which converts energy from one form into another (ex: Microphones & Speakers).

13. Define amplifier

A devices which takes a signal and increases its power.

14. Define signal processor

Devices and software which allow the manipulation of the signal in various ways.

15. Diagram (in your composition book) the 3 part model as described in the article.
