The frequency of a vibration, measured in Hertz (Hz), is the number of cycles per second. At its core, sound is a physical phenomenon driven by movement.
How Vibrations Create Sound Waves and Shape What We Hear
Conversely, a low frequency, where the vibration is slow, results in a deep, bass sound, such as a drum. Understanding what are vibrations in sound is the key to unlocking how we hear the world, from the lowest bass note to the highest birdcall.
This creates a wave of pressure that travels through the air, or any other medium like water or steel, until it reaches our ear. Therefore, the energy of the vibration directly correlates with the volume we experience.

, 50 Hz) Low Pitch (Bass, Tuba) Amplitude and Volume While frequency dictates pitch, the amplitude of the vibration dictates loudness. A vibrating object with a large amplitude pushes air molecules with more force, creating a higher pressure wave that our ears interpret as a loud sound.
