Aaert Equipment Exam Questions & Answers (100% VERIFIED)
Question 1:
sound
Answer:
is defined as vibrations that can be perceived
Question 2:
microphone
Answer:
converts the acoustical energy that is sound into an electrical signal that can be delivered to either an
analog or a digital device
Question 3:
analog and digital
Answer:
recordings start the same way; with sound
Question 4:
digital mixer or A/D converter
Answer:
to change the analog signal to a digital signal it will need to pass through an analog to digital converter,
commonly referred to as a
sample rate (44.1 khz, 48 khz,etc.)
Question 5:
bit rate (usually 16 or 24 bits)
Answer:
the two most important factors in the quality of the new digital audio are
Question 6:
low sampling rate
Answer:
approximation
Question 7:
high sampling rate
Answer:
smooth
, Question 8:
the bit rate
Answer:
represents the amount of information, or detail that is stored per unit of time of a recording
Question 9:
digital court reporting programs
Answer:
sample at a rate fast enough, thousands of times a second, so speech sounds are smooth and correctly
represented
Question 10:
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
Question 11:
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
Question 12:
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
Question 13:
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
Question 14:
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..
