What is the frequency response of a condenser microphone?
Condenser microphone summary
| Condenser Microphone Key Features | |
|---|---|
| Feature | Details |
| Typical frequency response | Can be as good as 20 Hz to 20kHz or better. |
| Typical applications | High quality sound recording, some sound support systems where additional sensitivity is needed. |
What is the frequency response curve of a microphone?
A frequency response curve is a graphical representation of how a microphone will respond in the audio spectrum and so, how it will affect a signal’s overall sound timbre. On a frequency response curve graph, the x-axis represents the signals measured frequency and relative response in decibels (dB) on the y-axis.
What is the frequency range of a microphone?
The frequency range of a microphone is defined as the interval between its upper limiting frequency and its lower limiting frequency. With today’s microphones you can cover a frequency range starting from around 1Hz and reaching up to 140 kHz.
Is 20Hz to 20KHz good for microphones?
The frequency response represents the range the mic is sensitive to within the audible sound frequencies. The microphone could effectively recreate the entire audible sound range from 20 Hz to 20 kHz, or it could be limited to a smaller band within the audible frequency spectrum.
What is a microphone frequency response specification?
Microphone frequency response is the frequency-specific output sensitivity of a microphone. It shows the relative output levels of the frequencies a microphone is able to reproduce from external sound pressure. Frequency response is specified as both a range and as a detailed chart.
Is 192khz MIC good?
The 192khz/24bit quality brings this microphone up and beyond standards. THIS MIC SOUNDS REALLY GOOD! FEATURES. In terms of features, typically with a microphone, you just want it to sound good and in my opinion, this microphone does!
What does the frequency response of a mic mean?
Frequency response defines the range of sound that a microphone can reproduce and how its output varies within that range. The frequency response is the most significant factor in determining the sound signature of a microphone. The frequency response of a mic is represented graphically by a response curve.
Which microphone has lowest frequency range?
Condenser microphones have the distinct advantage within the three in a typical industry application due to their insensitivity to vibration and the wide frequency (0.1Hz to 140kHz) and high dynamic (up to 140dB) ranges.
Is higher Hertz better for microphone?
The golden rule: the higher the sample-frequency is, the better is the sound-quality (although I think only a trained ear may able to resolve the difference). On the other side, a higher sample-frequency will lead to bigger audio-files in the case you perform records.
What kind of noise does a carbon microphone make?
The frequency response of the carbon microphone, however, is limited to a narrow range, and the device produces significant electrical noise. Often the microphone would produce a form of crackling noise which could be eliminated by shaking it or giving it a small sharp knock.
How does a carbon microphone work in a central office?
In telephony, this undulating current is directly passed through the telephone wires to the central office. In public address systems it is amplified by an audio amplifier. The frequency response of most carbon microphones, however, are limited to a narrow range, and the device produces significant electrical noise .
As we know our audio frequency range is from 20 Hz to 20 KHz. A good microphone is the device which respond well for this entire range of frequencies equally. Microphone converts audio signal into electrical signal which is amplified before being transmitted over cable. The same is reproduced back to audio form using loudspeaker.
When did they stop using the carbon microphone?
Carbon microphones, usually modified telephone transmitters, were widely used in early AM radio broadcasting systems, but their limited frequency response, as well as a fairly high noise level, led to their abandonment in those applications by the late 1920s.
