A sound with a frequency of 12,000 hertz would be categorized as which type?

Explanation:
Understanding how frequency maps to what we hear helps here. The human hearing range is roughly 20 Hz to 20 kHz. A sound at 12,000 Hz (12 kHz) sits squarely inside that range, so it’s audible to people. Ultrasonic refers to frequencies above about 20 kHz, which aren’t heard by humans, while infrasonic or subsonic are below our hearing threshold. So the correct category for 12,000 Hz is audible.
