What is the frequency response of a cell phone microphone?

What is the frequency response of a cell phone microphone?

Generally, an audio mic will be within a range of 20Hz – 20kHz. Many cheaper mics ( or intended for voice only) will have a lower cutoff frequency of 15kHz or less.

What is the best frequency response for a mic?

A microphone’s frequency response refers to the range of frequencies, from low to high, that a microphone will pick up. This range is referred to by its lowest and highest frequencies, measured in hertz. A microphone with a frequency response range of around 80 Hz to 15 kHz would make a good choice for a vocal mic.

What frequency does a microphone use?

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.

What frequencies can phones pick up?

Nowadays, mobile phones primarily use three technologies based on antenna cell networks.

• GSM (or 2nd generation mobile telephony – 2G) runs on the 900 MHz and 1800 MHz frequency bands.
• UMTS (or 3G) passes through the 900 MHz and 2 GHz frequency bands.

How do you read a mic frequency response chart?

The horizontal numbers in a microphone frequency response chart indicate frequencies (again, usually over the 20 Hz to 20 kHz range), and the vertical numbers represent relative output level in dB (decibels). As you look at a frequency chart, you can tell how a given microphone performs at certain frequencies.

What is the lowest frequency a phone can record?

It depends entirely on the phone, they will all use different microphones/circuits. Generally, an audio mic will be within a range of 20Hz – 20kHz. Many cheaper mics ( or intended for voice only) will have a lower cutoff frequency of 15kHz or less.

What’s the frequency response of an iPhone mic?

For example here’s an iPhone microphone frequency response comparison: http://blog.faberacoustical.com/2009/ios/iphone/iphone-microphone-frequency-response-comparison/ Also note that many people, especially the young, can hear up to 20 kHz and sometimes beyond so what you’re trying to achieve probably won’t be possible on most phones.

What kind of frequency does a mic catch?

That is the microphone may catch high frequency but with more attenuation than other frequencies. The mic has a resonance frequency where it has the maximum sensitivity and also there are circuits that deliberately attenuate inaudible frequencies.

Can a microphone pick up over 20 kHz?

Also note that many people, especially the young, can hear up to 20 kHz and sometimes beyond so what you’re trying to achieve probably won’t be possible on most phones. Apparently it is possible for a smartphone microphone to pick up on sounds that most people can’t hear, because:

What are the applications of a MEMS microphone?

MEMS microphones target all audio applications where small size, high sound quality, reliability and affordability are key requirements.
