When are the foam covers on the outside of a microphone only really necessary?
-
Every time you run sound
-
During extremely cold weather
-
At small indoor events
-
At outside events
Correct Answer
A. At outside eventsExplanation
Foam covers on the outside of a microphone are only really necessary at outside events. This is because outdoor environments often have more wind and environmental noise, which can cause interference and affect the quality of the sound. The foam cover acts as a windscreen, reducing wind noise and improving the clarity of the audio. In contrast, during small indoor events or every time you run sound, there may be less wind and environmental noise, making the foam cover less necessary. Similarly, extremely cold weather may not necessarily require foam covers, as the primary purpose of the cover is to reduce wind noise rather than protect against cold temperatures.Rate this question:

What are the two types of ways sound waves are converted through microphones?
-
Lapel and Countryman
-
Dynamic and Condenser
-
EQ and Frequency
-
Tango and Cash
Correct Answer
A. Dynamic and CondenserExplanation
The two types of ways sound waves are converted through microphones are dynamic and condenser. A dynamic microphone uses a diaphragm that is attached to a coil, which moves within a magnetic field to generate an electrical signal. It is rugged and can handle high sound pressure levels, making it suitable for live performances and recording loud sources. On the other hand, a condenser microphone uses a thin diaphragm that vibrates in response to sound waves, creating changes in capacitance. It requires phantom power and is more sensitive, making it ideal for capturing subtle details and recording vocals or acoustic instruments.Rate this question:

How does a condenser microphone work?
-
Uses a small charge placed across a metal plate to pick up sound waves
-
Sends a DB of 115 through a mic cable and into the soundboard
-
It pulls sound waves together to make them smaller
-
It suppresses sound waves down to a lower volume
Correct Answer
A. Uses a small charge placed across a metal plate to pick up sound wavesExplanation
A condenser microphone works by using a small charge placed across a metal plate to pick up sound waves. The metal plate, also known as the diaphragm, vibrates in response to the sound waves, causing the distance between the diaphragm and another fixed metal plate to change. This change in distance alters the capacitance of the microphone, which in turn produces an electrical signal that represents the sound waves. This signal can then be amplified and processed to produce the desired audio output.Rate this question:

How does phantom power work?
-
It makes you think you hear sound, but it’s just an illusion
-
It causes the lights to blink twice each time a microphone is plugged in
-
A large voltage is sent from the microphone and down a cable into the soundboard
-
A small voltage from the sound board is sent down a mic cable into the microphone
Correct Answer
A. A small voltage from the sound board is sent down a mic cable into the microphoneExplanation
Phantom power is a method used to power condenser microphones. It involves sending a small voltage from the sound board down a mic cable into the microphone. This voltage is used to charge the internal capacitor of the condenser microphone, allowing it to function properly. The microphone then uses this power to amplify the incoming sound signals and convert them into electrical signals that can be further processed by the soundboard.Rate this question:

-
The pull from the soundboard to the microphone
-
The pull from the microphone cable to the microphone itself
-
How microphone sensitivity is shaped
Correct Answer
A. How microphone sensitivity is shapedExplanation
Polar pattern refers to how microphone sensitivity is shaped. Different microphones have different polar patterns, which determine the directionality and sensitivity of the microphone. Some common polar patterns include cardioid (sensitive in front, less sensitive at the sides and back), omnidirectional (equally sensitive in all directions), and figure-eight (sensitive in front and back, but not at the sides). The polar pattern of a microphone is important in determining how it picks up sound and rejects unwanted noise from different directions.Rate this question:

-
Directly from the front, but rejects it from the back
-
Directly from the back, but rejects it from the front
-
Only from the side
Correct Answer
A. Directly from the front, but rejects it from the backExplanation
A microphone with a cardioid polar pattern picks up sound directly from the front but rejects it from the back. This means that the microphone is most sensitive to sound coming from the front and less sensitive to sound coming from the sides and back. The shape of the polar pattern resembles a heart shape, with the front of the microphone being the widest part and the back being the narrowest. This design allows the microphone to focus on capturing sound from the desired source while minimizing unwanted noise from other directions.Rate this question:

-
Only from the sides
Correct Answer
A. More directional from the front and slightly from the backExplanation
A microphone with a super, or hyper, cardioid polar pattern is designed to pick up sound more effectively from the front and slightly from the back. This means that it is most sensitive to sound coming from the front of the microphone, allowing it to capture sound sources directly in front of it with greater clarity. Additionally, it can also pick up some sound from the back, although to a lesser extent. This polar pattern helps to minimize unwanted sound from the sides and improve the focus on the desired sound source in front of the microphone.Rate this question:

How does a microphone that is omni directional pick up sound?
-
From all directions
-
From one direction at a time
-
From 3 directions
-
From the front only
Correct Answer
A. From all directionsExplanation
An omni directional microphone is designed to pick up sound from all directions equally. This is achieved through the use of multiple microphone capsules or by using a single capsule with a specially designed pickup pattern. The microphone captures sound waves coming from all angles, allowing for a more natural and immersive sound recording. This makes it suitable for capturing audio in a variety of situations, such as recording interviews, live performances, or ambient sounds.Rate this question:

Why are omni directional microphones not ideal for churches?
-
They only pick up sound from the congregation
-
They only pick up sound from the monitors
-
They pick up sound from the vocal as well as the monitors
-
They are the ideal for large churches only
Correct Answer
A. They pick up sound from the vocal as well as the monitorsExplanation
Omni directional microphones are not ideal for churches because they pick up sound from both the vocal source (such as the speaker or singer) as well as the monitors. This can lead to feedback and unwanted noise, as the microphone will capture sound from multiple sources simultaneously. Churches often require microphones that can focus on specific sound sources and minimize background noise, which is why omni directional microphones are not the best choice.Rate this question:

How does proximity effect enhance sound through a cardioid microphone?
-
Enhances high end the closer to get to the mic
-
Enhances low end the closer you get to the mic
-
Makes it wish it was a super-cardioid
-
Makes the sound look better
Correct Answer
A. Enhances low end the closer you get to the micExplanation
The proximity effect refers to the phenomenon where the bass frequencies are emphasized when the sound source is closer to a cardioid microphone. As the sound source gets closer to the mic, the low-end frequencies are boosted, resulting in a richer and warmer sound. This effect can be beneficial in certain situations, such as when recording vocals or instruments that require a fuller and more powerful low-end presence.Rate this question:

Fish sticks
Correct Answer
A. LimbsExplanation
Under extreme stress, an octopus may resort to a behavior known as autophagy, where it eats its own limbs. This self-destructive behavior is believed to be a survival mechanism when faced with extreme danger or when resources are scarce. By sacrificing their own limbs, octopuses can distract or fend off predators, allowing them to escape and regrow their lost limbs later. This unique ability to regenerate limbs makes them capable of surviving such extreme circumstances.Rate this question:
