What frequency range does the FET microphone extend to?

The correct answer reflects the typical frequency range of FET (Field Effect Transistor) microphones, which are known for their wide frequency response. FET microphones commonly extend from about 30 Hz to 18 kHz, allowing them to capture a broad spectrum of audio signals. This range includes both low and high frequencies, which is crucial for accurately reproducing sound in various applications, such as music recording or hearing aids.

The frequency response is particularly significant because it defines the audible range of sounds that the microphone can effectively pick up, ensuring that both bass notes and treble notes are captured. A standard FET microphone’s ability to function well within this range makes it versatile for different acoustic environments and requirements.
