selecting an&nbsp;electret microphone, the capsule size is more than just an installation constraint. The diameter primarily determines the diaphragm area and the number and size of acoustic pickup holes, which together shape the microphone\u2019s tonal character and frequency response. Why Size Matters in Electret Microphones Unlike internal electronics (JFET or MOSFET) that influence sensitivity and noise, microphone size mainly affects its&nbsp;acoustic properties.
