When is extra protection needed above other noise control measures?
where extra protection is needed above what has been achieved using other noise control measures. The risk of occupational noise-induced hearing loss is increased by relying too much on, and improperly using, personal hearing protectors such as ear muffs and plugs.
Why does my water heater make a rumbling noise?
Water heaters can also cause rumbling noises due to bits of sediment, rust or limescale heating up and expanding within the cylinder. Rumbling noises can also stem from very high pressure. If the incoming main water supply has too much pressure, valves inside your house can hum or whine, so it’s important to check if you need to readjust.
Why is my power converter making a loud buzzing noise?

Why does my power supply make a humming noise?
The cause of most humming in power supplies is due to the vibration of transformer core ‘laminations’ against each other. The amount of hum varies with the strength of the magnetic field being produced by electrical demanded in the equipment. Transformer cores are made of a stack of thin sheet metal stamped parts, not a single piece of solid iron.
Why do I hear a whining sound from my PWM drive?
The whining sound you hear is from the pulse width modulation of your servo drives. The earlier versions used a lower frequency to accomplish this since faster power transistors were not available. This frequency was in the audible range, less than 10,000 cps. Now later PWM drives switch at 20,000 or more cps, so you don’t hear them.
