Microphone sensitivity, frequency response charts and Compression between dynamic and condenser microphones.

Microphone:

A microphone is a device that converts sound or acoustic energy into electric energy.

A microphone that produces a strong signal is referred to as having a higher sensitivity than one that produces a weaker signal. Sensitivity is very important for any microphone. It depends on diaphragm and its size, thickness, materiel.

Microphone sensitivity and frequency response charts:

A microphones frequency response refers to its sensitivity over its operating range from lowest to highest frequencies. A microphones frequency response chart is a graphic representation of his sensitivity over its operating range usually between 20 Hz and 20,000 Hz. This is the approximate range of human hearing.

 

The vertical row on the left reads decibels this measures amplitude and the horizontal row on the bottom represents the frequency range from lowest on the left to highest on the right. A perfect microphone we register all frequencies are crossed a “0 dB” level. It would be a natural sounding microphone to ask because this is how we hear microphones with graphs that look like this are referred to as having a flat frequency response.

One thing we need to know is that if two different audio microphones of different manufacturers are kept in the same frequency and the Frequency response curve will be different.

Dynamic microphones
Dynamic microphones make their signal as the result of motion inside the microphone. If I speak into a dynamic microphone, it makes electricity as a signal. This signal travels down to my cable but is too weak to be used. It needs to be amplified first with what is called a pre-amplifier or preamp. Pre-apps can be separate components are built into amplifiers and interfaces.

Advantage Disadvantage

The main advantage of dynamic microphones as they work best in high sound level applications such as vocals drums and guitar amps. And they are very durable which makes these microphones perfect for the road and Stage applications.

The main disadvantage of these microphones is it may have some sensitivity limitations and it may miss some detail and recording applications.

 

 

 

Condenser microphones
When you speak into the condenser microphone without external power no signal is being produced because condenser microphones make their signal with electric components in the microphone. These kinds of microphones need a source of electricity to make their signal this is called phantom power.

Advantage Disadvantage

The main advantage of condenser microphones is there sensitivity. These microphones are predominantly used in recording studios to make the best possible recordings.

Condenser microphones and it’s disadvantages is due to their Construction since they are electronic they are not as durable as Dynamic microphones.

 

It is up to you the artist to determine which microphones sounds best to you.
