A sound with a frequency of 5000 Hz falls into the category of **normal range**.

The normal range of human hearing is typically between 20 Hz to 20,000 Hz (20 kHz). Sounds below 20 Hz are classified as infrasonic, while sounds above 20 kHz are classified as ultrasonic. Supersonic refers to speeds exceeding the speed of sound, rather than a sound frequency. Therefore, 5000 Hz is well within the normal hearing range for humans.
