Hello, I hear this constant high pitched noise, almost like ringing, but even ... pitch

Hello there!
Sometimes High pitching its just that, static on the area, like if you are near a microwave, or near other electronic equipments, but, if the skreetching sound keep going or even if you do nothing it could be a line inside the sound card, or you need to clean the volume botton with special electrical cleaner. other that these, its contacts, or bad cap for the volume board inside.
Good Luck!

If the starter did not have a shim dont put one in if the start is make the nosie without the shim the new starter is bad (ase)certautotech

Could be a bad fan assembly.

If it is a relatively quiet, high pitched noise, it may not even be from your speakers. I've experienced a high pitched noise whenever i plug in my AC adapter to my PSP, so there is a chance it might be power related.

Hi,
I have a Mac (OS X 10.5.7) and had the same problem with the Ion TTUSB system picking up room noise. This seemed to fix it: 
In System Preference, under Hardware, choose "Sound".
Choose "Input".
Under "Choose a device for sound input" choose USB Audio CODEC  type: USB

I hope this helps,
Cheers!

Looks like the printers internal electrical components have gone. if there is a tranformer in your printer then that is making that noise. or else even the motors might also be gone.

my strong suggestion take it to any authorized service personnel

According to the Samsung website: "The high pitched sound you hear is probably coming from the flyback transformer. The flyback transformer converts the relatively low voltage electricity that comes from the outlet in your home to the high voltage electricity needed to drive the cathode ray tube in your TV. It is not unusual for a flyback transformer to buzz softly when it operates. However, if the sound is loud and high pitched, it probably means the transformer is failing. To eliminate the sound, you will have to get your TV serviced."

Be more specific. I guess your monitor has inbuilt speakers which are making noise. If yes do come back for a solution.

Could you specify if noise is coming from : - The freezer - The outside back of the refrigerator - The bottom of the refrigerator
