I am a 27 years old guy and I have a very bad ear at hearing high frequencies, I only figure out this today after doing more than 20 hearing tests (diff websites, videos, apps ect..) The result is I couldn't hear anything above 8khz on all these tests with regular average volume. Eventually what I did is, generating a pure sine wave then play it in whole human audio spectrum (20hz--20khz) I tried this with both headphones/earphones and speakers. if I turn up the volume 100% the highest frequency I can hear is 13khz, I could hear absolutely nothing after 13khz. I don't have any hearing problem or any difficulty hearing quiet noises (except these high frequencies) and I am also a musician and I have a good relative pitch, I can sing any note perfectly in tune if you give me a reference note and I am able to recognize any melodic/harmonic interval with no effort. Also there's one thing I didn't understand, there was one videos on youtube I tried, it was a sine-wave raising the pitch gradually from 20hz to 20khz, on this video I stopped hearing at 13khz on 100% volume but at 15Khz I started hearing again (something that sounded much lower than what the frequency must be, I would say) the sound is like a tape drop effect or like when you do a drop with the guitar whammy bar, which is very weird espeially that the audio is only a sine-wave which means there's only one harmonic which is the fundamental, so I converted this youtube video and played it on my DAW and opened a detailed graph to visualize what is happening. I saw nothing except a normal sinewave increasing the pitch! still hearing this weird thing after 13khz! is this normal ? Do I have some hearing problems ?

 

See an audiologist

 

Almost sounds like you are describing a Shepard Tone!
Have you recently done acid aurally?

 

Join the club..
Loss of hearing is kind of normal for people living today. Listening to loud music on headphones, visiting clubs, parties and concerts.. All of them are non healthy habits that our ears don't like.
But a test is one thing, 8 kHz and above is where harmonics of ground tones reside, without them you can still hear 'enough'..

I would repeat the test in a year or so, and check if your hearing got worse. Of course, change any habit of listening to loud music, also be very careful of sudden loud noises, that could be present at work or daily life.
@Smoove: lol, you mean orally, aurally is through the ears!

 

indeed ..his english is horrible

 

I think he said this on purpose, to make us laugh (creative and good sense of humour). Otherwise he could've stopped at "acid".

 

Don't do tests on YouTube. There is horrible aliasing and codec artifacts, and some frequencies don't go over 13k.
Do proper tests at an audiologist (who uses lossless audio and proper digital/analog gear for their tests).

 

Thank you everyone, I wanna mention that I don't work in loud environment, I don't listen much to loud music, I am not on any medical condition or taking any medicines. Yes I understand that a test should be done with professional audio equipment (unfortunately I don't have access to an audiologist in the place where I live). I know these tests online might be inaccurate but I tested many of them on graph and I saw that there was audio signal after 13khz, I still couldn't hear anything, no matter how loud my volume is. For me when the sine-wave reaches 13Khz I feel a very high sharp noise that I can't even imagine something higher, I was surprised seeing people my age commenting they could hear up to 17khz and 18khz on the same tests I done, which made me worry if I am having hearing loss or something ? I don't know if my hearing have been always like this or not but usually I am the guy who always hear better than my family or friends.

here's 2 screenshots of tests I done on different audio devices and the outcome is always the same :

 

Could be just temporal hearing loss and fatigue. Happens when you listen to a lot of loud music on headphones, i am talking hours and hours for weeks or months.
While it could be you have damaged the inn ear hair/cells it is many times brain damage.
If you also suffer from very bad sleep or insomnia, depression, anxiety, tiredness it means your brain is very fatigued and damaged to the point where even modestly loud music or high frequencies could invoke actual inner ear pain.
It takes some time to heal due to the prostaglandin e2 and other stress hormones accumulation in your brain but you need to take a break from music and music production for at least a month.
Take a lot of vitamins, ammino acids, l-glutamine and l-arginine, fish oil omega 3 and herbs like ginseng to help you out, also take a lot of rest and get a good sleep.

 

Thank you, I will try to avoid the most possible noises for some time and see how it goes. I am thinking to buy some earplugs and use them most of the day too, what do you think ?

 

Avoiding loud music or any music will do, watch tv on low volume, just live peacefully for a while, do some reading, walk outside.

 

There can be several reasons for this.
I'd first go to an ENT specialist and try to find out if there is a physical cause.
If not, than maybe visit a psychologist because this can in deed have also psychological reasons.

Depending on the person may not be the best. The ears benefit from fresh air.

 

Someone alluded to this but make sure the headphones/speakers you are using actually respond at high frequencies. Otherwise you are mostly testing the frequency response of the equipment and not your hearing. Listening device must be calibrated and could have uneven response causing dropouts or peaks at certain frequencies.

And through the ears is what I meant! lol. Hence aurally/audiosex etc.
I'm quite well read you know!
You know what a shepard Tone is?

 

I wrote exactly what I meant! "Aurally": in the ears.

 

Good luck @Jackson12 . What you described needs to be sorted if possible.
I had a friend who has always had the best record collection throughout my life, but since a teenager he was aware he wasn't 'getting' it all.
Only 2 years ago, in his 40s, did he get some of those amazing, new, tiny hearing aids. Can't even see them.
They also cancel out his tinitus with lots of different sounds including pink noise or white noise or something.
He's so happy now!

 

Aha, it's got a name, Shepard tone. I've got this ambient track: "Endlessly downwards" by Beatsystem, which is created around that principle. Nice.. thanks!

 

roughly same age here, I barely can hear anything over 14kHz and I don't care to be honest

 

Thank you again everyone for your participation, I wanna ask something, do people like me have problems hearing some noises ? because I read that some of the people who have problems hearing high frequencies can't hear birds properly and sometimes have problems understanding people talking. I don't have any problem like that, I actually can tell you notes played on piano on the last octave which are betweek 2khz and 4khz if you give me a reference note. I didn't think I have a problem at all till I did these tests by curiosity one day. I do want to believe it has to do with calibration but I tested this with a pure sine-wave generator and a studio headphones that has good frequency response (20hz--20khz) I still can't hear anything above 13khz always even if the volume and the input is at its max, I can still see the signal although.
