What is the frequency response of a cell phone microphone?

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 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.

What determines microphone sensitivity?

Microphone sensitivity is a measurement of a microphone’s efficiency as a transducer (how well it converts acoustical energy to electrical energy). A microphone’s sensitivity rating is determined by its output voltage (audio signal strength) relative to the sound pressure level it is subjected to.

What frequencies can phones pick up?

Telephones can only pick up frequencies above 300 or 400 Hertz (cycles per second, also called Hz), but most adults’ speaking voices are lower than 300 Hz (approximately the D above middle C). And yet every day, people manage to have telephone conversations.

What is microphone resonance?

The microphone membrane is typically designed to have higher resonance frequency than the working audible bandwidth, which is less than 20 kHz. Thus, the microphone resonance is the mechanical characteristics of the microphone membrane.

What described output of a microphone over a range of frequencies?

Microphone frequency response
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.

Where is the microphone on my phone?

On an Android phone, it’s just the “Camera Microphone,” which should use the mic near either the rear or selfie camera, depending on which you’re using. The standard mic options on a newer iPhone model.

What is the difference between a microphone and an external microphone?

The following sections describe both, as well as how to detect these devices using software. External microphones are peripherals that are usually purchased separately and plug into the computer. Essentially, if you do not have a microphone attached to your sound card or to a USB port, you do not have an external mic.

How do I know if I have an internal or external microphone?

If you have an internal or external microphone, it displays in the middle section. If you have more than one input device, you can switch to another by selecting it, and then clicking the and buttons. The information in this section helps you determine if you have an internal or external microphone on a computer or laptop running macOS.

What is impulse response on a microphone?

Impulse response shows the speed and precision of a mic to create fast transients. A good mic will reproduce fast transients with accuracy. If your mic has slow impulse response than expected, the chances are that the mic is damaged.
