The electric toothbrush produces a characteristic sound during operation, which can be described as a gentle humming or buzzing. When turned on, it may generate a constant and relatively quiet sound emanating from the movement of the brush and the rotation of its head. This sound can be associated with a low-frequency buzz, typically considered calm and unobtrusive. Modern electric toothbrushes often emit such a sound to inform users that the device is in operation, yet it remains relatively unobtrusive. The recorded sound also includes the effect of the brush moving from side to side.
