1. What range of frequencies are detectable to the human ear?Approximately 20Hz. To 20kHz. 20Hz is the lowest pitched (bassiest) sound we can hear, 20kHz is the highest pitch we can hear.
2. Define AudioAudio means “of sound” or “of the reproduction of sound”. It refers to the range of frequencies detectable by the human ear.
3. Audio production involves what four elements of audio?
4. List 10 careers in audio and list a local company for six of the career fieldsStudio Sound Engineer, Live Sound Engineer, Musician, Music Producer, DJ, Radio technician, Film/Television Sound Recordist, Field Sound Engineer, Audio Editor, Post-Production Audio Creator.
5. List three careers that need to have an understanding of audio production concepts
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 waveformA waveform is a 3-Dimensional wave that travels along a path from left to right.
8. Is sound two dimensional or three dimensional?3-Dimensional
9. How do variations in sound pressure correlate to a waveform diagram?The waveform diagram is in 2-D while
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 transducerA device which converts energy from one form into another.
13. Define amplifierA device which takes a signal and increases it’s power.
14. Define signal processorDevices 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.
