The pickup range of an electret microphone capsule depends on its internal design, manufacturing quality, intended application, and the environment in which it is used.
In general, electret mic capsules have a relatively wide pickup range and can capture a broad spectrum of sound frequencies.
Many standard electret microphones offer a frequency response of 20Hz to 20kHz, which fully covers the range of human hearing.
High-end electret microphones may feature an even wider range, allowing them to capture extremely low or high frequencies depending on specific application needs.
It is important to note that the actual pickup range during use may be affected by factors such as the connected recording equipment, power supply, and surrounding acoustic environment.
