Frequency refers to the number of complete vibrations or cycles a sound wave makes in one second. In relation to high-pitched sounds, they have a higher frequency compared to low-pitched sounds.
The cochlea is an inner ear structure responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. It plays a crucial role in perceiving different pitches, including high-pitched sounds.
