Somebody's turned the telly on and you can hear the picture electronics working. It seems to come from nowhere because with high frequency audio it is more difficult to determine direction. (Unless you're a bat of course).

If you only hear it occasionally you may be hearing the high frequency radiation of a large power transformer. Things like humidity and temperature, maybe even ear-wax, can affect it because it can attenuate the signal.
If you get it regularly I believe you may have circulation problems. It can also be associated with slight tingle or coldness in extremities of your fingers or occasional difficulty with short term memory. I had this and when I discovered the cause, through herbal medicine. I found Ginkgo effective in treating it.
If you have a circulation problem and are a smoker you will notice an intensification of the tone when you smoke. That is the best proof I know that smoking is harmful to your circulation.

It can be tinnitus. You'd need tests done to confirm this. A lot of people get it at some time or another. It can be due to earwax, circulatory problems, a build-up of static charge, or damage to the inner ear, and can get worse with old age.
It's essentially due to the nerve cells in your inner ear misfiring, which your brain interprets as a constant tone.
In most people it will pass in a few seconds. However, if your hearing has been damaged somehow, possibly by loud noise or a head injury, it can last for weeks at a time and become agonisingly loud. Since it's not a "real" noise, it can't be blocked with earplugs.
On a more metaphysical note, some have referred to it as "the singing" and associated it with places where deep thought or emotion had occurred.

the difficulty including your question as you have asked that's that an audio recorder will do only that; record the variety of human listening to. The audio circuits are actually not designed to technique sounds at larger frequencies; even with the certainty that the person-friendly limitations are (a million) the microphone getting used, and (2) the frequency recording characteristics of the recordplayback of the device doing the recording. There are contraptions interior the scientific community which could record ultrasonic sounds and play them back so as that the human ear will pay attention them. the technique they use is to record the sound at a definite tape velocity (say 15 inches consistent with 2nd) and play them back at a slower velocity (for example, 7.5 or 3.seventy 5 inches consistent with 2nd. this might effectively halve or quarter the frequency, reducing the frequency of the recording to the variety of human listening to. the swifter the preliminary tape velocity, and the slower the playback velocity, determines the final playback frequency. The trick right that's to have the two a microphone and recorder able to shooting those ultrasonic vibrations. think of in terms of $$$ quite than $$.

Are you biking or travelling by vehicle in the cold exposed to the wind? I mean without proper head covering gear? It is a general reaction we get in the cold which usually goes off. If it persists see a ENT specialist.

Could be tinnitus (hearing imbalance) Go & have it checked with your GP. he/she should be able to do a basic test, then refer you on. Hopefully you'll get the right help B4 it gets too troublesome.
Loads of jokes I could make here, but won't, cos it's not funny at all if you have to put up with it on a daily basis.
Wish you well

By turning down the volume on your hearing aid the high pitched noise you can hear, otherwise known as 'feedback' will disappear and stop altogether.

apparently it happens when your blood sugar levels drop, so basically when you are hungry or haven't had enough to eat. A friend told me this ages ago so i have no idea if it's true but it does seem to correspond once you notice.

its caused by earwax moving around and somtimes causes an air pocket which gives that annoying high pitch, have you got or recently had a cold?
