There is almost no noise generated by the capacitor itself; however, when a capacitor is mounted on a board the vibration increases, and when the cycle of the amplitude reaches the audible frequency range (20Hz 20kHz) of humans, it can be heard as a noise. For example, the noise sounds like a quot;hum,quot; quot;hiss,quot; or a high pitched tone.
