Which frequency range represents audible sound?

Explanation:
Audible sound typically encompasses the frequency range between approximately 20 Hz to 20 kHz (20,000 Hz). Humans can generally hear sounds in this frequency range, with the lower threshold being around 20 Hz and the upper limit around 20 kHz. The choice of 18 kHz falls within this range, thus representing a frequency that is categorized as audible sound. Frequencies below this range, such as 15 Hz or 2 Hz, would be considered infrasound and are not perceivable by the average human ear. Similarly, frequencies above 20 kHz, such as 25,000 Hz, fall into the category of ultrasound, which is also beyond human hearing capabilities. Thus, the choice of 18 kHz accurately reflects a frequency that is within the human audible spectrum.
