Topic 1: Microphones and Audio Equipment (Questions 1-15)
1. What is a cardioid microphone pickup pattern?
Correct ,,,,,,,,,answer,,,,,,,,,: A heart-shaped pickup pattern that reaches
out from the diaphragm and is most sensitive to sound coming from
directly in front of the microphone.
Rationale: The term "cardioid" comes from the Greek word
"kardioeides" meaning "heart-shaped." This pattern is ideal for
courtroom settings because it focuses on a single voice in front while
rejecting ambient noise from the sides and rear. Super-cardioid and
hyper-cardioid patterns have even narrower areas of sensitivity .
2. What is an omnidirectional microphone pickup pattern?
Correct ,,,,,,,,,answer,,,,,,,,,: A pattern that picks up sound equally from
all directions.
Rationale: Omnidirectional microphones are useful when you have
multiple speakers but only one microphone available for recording. They
capture sound evenly from all angles. Some microphones have switches
that allow you to change between pickup patterns. This pattern is less
common in depositions where individual speaker isolation is preferred .
3. What is a dynamic microphone?
Correct ,,,,,,,,,answer,,,,,,,,,: A moving-coil microphone that uses a
,diaphragm, coil, and magnet to convert sound into an electrical signal.
Rationale: In a dynamic microphone, the diaphragm is a flat plate at the
front. When sound energy hits the diaphragm, it moves the attached coil
back and forth over a magnet, generating an electrical signal that travels
through wires to the digital mixer. Dynamic mics are generally bulkier
but more durable than condenser mics .
4. What is a condenser microphone?
Correct ,,,,,,,,,answer,,,,,,,,,: A microphone that uses a front plate
(diaphragm), back plate, and 48V power source (phantom power) to
capture sound.
Rationale: The front and back plates form a capacitor. When sound
energy hits the front plate, the distance between the plates changes, and
the gap is electronically charged by phantom power. Condenser mics
come in wider assortment of shapes and sizes than dynamic mics,
including gooseneck, lavalier, and low-profile boundary models .
5. What is a low-profile boundary microphone?
Correct ,,,,,,,,,answer,,,,,,,,,: A flat microphone that lays on a surface,
typically one to two inches thick.
Rationale: These microphones are designed to lie flat on conference
tables or witness stands. However, they have drawbacks: they pick up
lots of ambient noise and can easily get covered by papers or other
objects, which significantly degrades audio quality. They require careful
placement to be effective .
6. What is a lavalier microphone?
Correct ,,,,,,,,,answer,,,,,,,,,: An extremely small condenser microphone
that attaches directly to the speaker's clothing.
Rationale: Lavalier mics are used when there is no opportunity to place
a microphone in front of the speaker. They are available in both wired
and wireless versions. For wireless lavaliers, having spare batteries is
essential. These are common in deposition settings where speakers move
around or gesture frequently .
, 7. What is a gooseneck microphone?
Correct ,,,,,,,,,answer,,,,,,,,,: A microphone with a solid base and long
flexible neck that extends a narrow condenser toward the speaker.
Rationale: Gooseneck microphones are common on witness stands and
judge's benches. They typically have a toggle switch to turn them on and
off. The flexible neck allows precise positioning toward the speaker's
mouth while keeping the base mounted in place .
8. What are XLR connectors?
Correct ,,,,,,,,,answer,,,,,,,,,: The most common type of microphone
connectors, referred to as microphone cables.
Rationale: XLR connectors are the professional standard for balanced
audio connections. They are three-pin connectors that provide a secure,
locking connection and better noise rejection than consumer-grade
connectors like 1/4-inch or RCA plugs .
9. What happens when a room has plaster, marble, and wood
paneling?
Correct ,,,,,,,,,answer,,,,,,,,,: It results in an acoustically "live" room with
significant sound reflection.
Rationale: Hard, non-porous surfaces reflect sound rather than absorbing
it. This creates echo and reverberation, which can make recordings
difficult to understand. Digital reporters must be aware of room
acoustics and may need to adjust microphone placement or use
additional sound absorption materials .
10. What is the primary responsibility of an electronic reporter
regarding audio?
Correct ,,,,,,,,,answer,,,,,,,,,: Obtaining a high-quality recording.
Rationale: While annotation and chain of custody are important, the
electronic reporter's fundamental duty is to capture a clear, usable audio
recording of the proceeding. Everything else depends on this primary
function. If the recording quality is poor, transcript production becomes
impossible or unreliable .
