AAERT CERTIFICATION EXAM 8 PRACTICE
QUESTIONS AND DETAILED SOLUTIONS
◉ the bit rate.
Answer: represents the amount of information, or detail that is
stored per unit of time of a recording
◉ digital court reporting programs.
Answer: sample at a rate fast enough, thousands of times a second,
so speech sounds are smooth and correctly represented
◉ when selecting the microphones that you will use there are
several variables: these variables include.
Answer: Microphone type (dynamic or condenser)
microphone pick-up pattern
microphone size and stands
microphone cost
◉ for the purpose of digital reporting, AAERT recommends that you
slect.
Answer: dynamic, condenser, or a combination of dynamic and
condenser microphones. Both of these microphone types work in a
unique way but can generate a high quality audio reproduction
, ◉ dynamic microphones.
Answer: (also called "moving coil" microphones) are made up of a
diaphragm, a coil, and a magnet. As acoustical energy hits against
the diaphragm, which is a flat plate at the front of the microphone, it
causes the coil that is attached to it to move back and forth over top
of the magnet . they are bulky
◉ condenser microphone.
Answer: consists of a front plate (diaphragm), back plate, and a 48
volt power source. The front and back plate together create a
capacitor. wider assortment of shapes and sizes. one type commonly
used is a gooseneck microphone
◉ phantom power.
Answer: when acoustical energy hits the front plate of the capacitor,
the distance between the front and back plate changes. the gap
between these two plates is electrically charged. this charge is
created by either an internal battery source or an external power
source referred to as ..
◉ aaert does not recommend:.
Answer: the use of batteries as the supply of this charge. if a battery
would die during use, you could have a gap in your recording and
