AUDIO NOTES: REFOCUS Clarifying and focusing our studies for the Unit Three Test!

ACOUSTICS Live room vs. Dead room What type of room is Terlecki’s room with a full class of students? What type of room is Terlecki’s room with no students? What makes a room Live or Dead? What kind of materials absorb sound? Soft materials i.e.: Styrofoam, spray foam, people What kind of matertials reflect sound? Hard materials i.e.: tile floor, desks, wood, metal, block

MICROPHONES What are the four parts that make up a microphone? Diaphragm Metal Coil MagnetGenerating Element Backplate Classifying mics Type: Ceramic, Dynamic, Ribbon, Condensor, PZM Pickup Pattern: Omnidirectional, Directional Mic Mount: Table Stand, Floor Stand, Boom, Handheld You can be specific i.e.: An omnidirectional, ribbon, boom mic

TYPES OF MICS Ceramic/Crystal Cheap Not for important audio/video Where do you see this daily? Dynamic Tough/Durable Where do you see this most often?

IMPEDENCE What does it mean to “impede” someone or something? To block, interfere, or stop Think about a race…
