An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
The ear's shape also allows the sound to be heard more accurately. Many breeds often have upright and curved ears, which direct and amplify sounds. As dogs hear higher frequency sounds than humans, they have a different acoustic perception of the world. [24] Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs.

An unexplained high-pitched tone has kept residents of a Portland suburb awake at night for at least a week.
Treble describes tones of high frequency or high pitch, ranging from 6 kHz to 20 kHz, [1] comprising the higher end of the human hearing range. In music, this corresponds to high notes. The treble clef is often used to notate such notes. [2] Treble sound is the counterpart to bass sound.
A cacophony of high pitched beeps and blasting symphony music – emanating from speakers on the building at the street corner – make most passersby not want to stay too long.
Ululation (/ ˌ j uː lj ʊ ˈ l eɪ ʃ ən, ˌ ʌ l-/ ⓘ, [1] [2] from Latin ululo), trilling or lele, is a long, wavering, high-pitched vocal sound resembling a howl with a trilling quality. It is produced by emitting a high pitched loud voice accompanied with a rapid back and forth movement of the tongue and the uvula. [3]
