What is the purpose of a microphone?

• To record video

• To charge a phone

• To convert sound waves into electrical signals

• To play music

Name one type of microphone commonly used in recording studios.

• Ribbon microphone

• Shotgun microphone

• Condenser microphone

• Dynamic microphone

How does a dynamic microphone work?

• A dynamic microphone functions by amplifying sound waves through a series of filters.

• A dynamic microphone works by converting sound waves into digital signals directly.

• A dynamic microphone operates by using a laser to capture audio vibrations.

• A dynamic microphone works by using a diaphragm attached to a coil of wire within a magnetic field. When sound waves hit the diaphragm, it vibrates, causing the coil to move within the magnetic field and generate an electrical signal.

What is phantom power and why is it used with certain microphones?

• Phantom power is used to provide power to microphones with active electronic circuitry, such as condenser microphones.

• Phantom power is only used with dynamic microphones.

• Phantom power is used to reduce background noise in microphones.

• Phantom power is used to make microphones sound louder.

Explain the difference between cardioid and omnidirectional microphones.

• Cardioid microphones are more directional, picking up sound primarily from the front and rejecting sound from the sides and rear. Omnidirectional microphones pick up sound equally from all directions.

• Omnidirectional microphones are more directional, picking up sound primarily from the front.

• Cardioid microphones pick up sound equally from all directions.

• Cardioid microphones reject sound from the front and pick up sound from the sides and rear.

What is the frequency response of a microphone?

• Frequency response of a microphone is the weight of the microphone

• Frequency response of a microphone is the color of the microphone

• Frequency response of a microphone is the brand of the microphone

• Frequency response of a microphone is a graph that shows how sensitive the microphone is at different frequencies.

What is the polar pattern of a microphone?

• Directional sensitivity pattern of a microphone

• Cardioid sensitivity pattern of a microphone

• Bi-directional sensitivity pattern of a microphone

• Omnidirectional sensitivity pattern of a microphone

What is the proximity effect in microphones?

• The proximity effect in microphones is the increase in treble or high-frequency response when the microphone is placed close to the sound source.

• The proximity effect in microphones is the distortion of sound when the microphone is far away from the sound source.

• The proximity effect in microphones is the increase in bass or low-frequency response when the microphone is placed close to the sound source.

• The proximity effect in microphones is the reduction in bass response when the microphone is close to the sound source.

What is a condenser microphone and how does it differ from a dynamic microphone?

• A condenser microphone is less sensitive than a dynamic microphone and captures a narrower frequency range.

• A condenser microphone uses a capacitor to convert sound waves into electrical signals, requiring phantom power to operate. It is more sensitive and captures a wider frequency range compared to a dynamic microphone, making it ideal for studio recordings and capturing subtle nuances.

• A condenser microphone does not require any power source to operate, unlike a dynamic microphone.

• A condenser microphone uses a magnet to convert sound waves into electrical signals, similar to a dynamic microphone.

Why is it important to use a pop filter with a microphone?

• To increase background noise

• To reduce or eliminate popping sounds caused by plosive consonants.

• To improve microphone sensitivity

• To add weight to the microphone
