its due to intermolecular collision of magnetic domain .nd its also due to magnetostriction ..
Shielded transformer
To stop the buzzing of a doorbell transformer, you can try tightening any loose connections, replacing the transformer, or installing a noise filter.
The noise from a transformer, even in the absence of rotational loss, primarily arises from magnetostriction, which is the phenomenon where the magnetic material in the core changes shape slightly when it is magnetized. This change in shape causes vibrations that produce audible sound. Additionally, electrical noise can result from the movement of currents and the interaction of magnetic fields within the transformer, contributing to the overall noise output.
have seen in the past , fuel pump moan/noise on this make & model / from a ford tech.
Spacers insulate the transformer tank from the mechanical vibrations of core & the windings.this results in reduced noise emisions.
transformer
An isolation transformer (or more commonly, amplifier) reduces noise in the system from the power source. This is especially necessary in medical applications where the signals that are being read are very tiny and even a small amount of noise can disrupt a signal and make it unreadable.
Common bad transformer symptoms in HVAC systems include frequent system cycling, blown fuses, inconsistent heating or cooling, and a humming or buzzing noise coming from the transformer. These issues can indicate a malfunctioning transformer that may need to be replaced.
A bad compressor belt can cause a whistling noise while running the air conditioner. A bad engine can also cause this noise.
A car that is in good running condition should not make a clunking noise. If a person pushes the gas and brake pedal at the same time causing a car to make a clunking noise, that is an indication of stain on the motor.
It is not abnormal to make a loud stomping noise when running, as it can be caused by factors like running technique, shoe type, and surface being run on. However, it may be beneficial to work on running form to reduce impact and noise.
No, this HP laptop should make little to no noise while running with no programs on.
