If there's a difference, especially in bass frequencies, go get your Eustachian tubes checked. I cleaned my ears over and over with Debrox, hydrogen peroxide, q-tips, etc. Turns out, the tubes under the ear drum can be plugged by allergies/inflammation and you cannot get to these with q-tips. So, go see your nose, throat, and ear specialist and have them check. I was prescribed Flonase and Zyrtec, and it takes a few weeks to clear the tubes.

[@jeffgAdventures]

I've listened to this in two rooms, one on LS50 Wireless powered speakers nearfield, and the other on Sierra-II Ex powered by Aventage receiver. Both exhibited oddities between left and right versions of the same frequency. These sounds do not appear to be recorded equally left vs right. Nor are all frequency the same volume. I've used both ears mono style and listened in Stereo.

[@blandrooker6541]

[@activemusickid]

Is anybody else perceiving the sound slightly sharper or flatter in one ear versus the other ear ?? It's very slight... I checked on my monitors and headphones and noticed this... Anyone else ??

[@zlonewolf]

Plug the leg earphone or put the left earmuff on the left then the right. If its not equal in sound then you got a dirty plug into aux or your ears are getting bad on one side or your headphone/in-ear phone is bad. Im leaning toward your bad earphone if you can hear the left (good) earpiece well on left and right but that right earpiece is lower volume. Unless maybe this test itself isnt set correctly. To test if this test is faulty, play it thru a bookshelf speaker. You should hear both speakers equally. If it also is lopsided then either test is bad or maybe even your speakers are bad.

Thank you so much this helped my son to prepare for a hearing test🙏🙏🙏

[@DustInTheWindAZ]

As I was listening on headphones, I notices some of your test tones were not identical in the left and right channel; one was flatter than the other. The 250Hz tone has a "warble" in it. It DID tell me, however, that my hearing loss starts at 5KHz in the right ear and both ears at 10KHz. Perhaps I should reverse the headphones (L to R) and try other headphones and speakers to get a more objective result.

[@DustInTheWindAZ]

Same results with the headphones reversed...

[@4thesakeofitname]

Right and left ears can have small hearing differences to some extent just like right and left eyes do for vision. Headphone frequency response, and any equalizers before the audio driver will also have an effect on the final produced acoustic signal. The fact that 1 kHz tone sounded much louder (to both ears) than 10 kHz tone does not mean that one has hearing loss: it's normal, human ear frequency response is not flat. One should pre-amplify high (and low) frequency signals to make the sound as loud as the reference 1 kHz tone. And I don't think so this was done on this record. So, one should turn the volume up to get a justified testing of hearing loss at high frequencies. Also one should better check on a finer grid including 6 kHz, 8 kHz, 12 kHz for getting a better picture of the hearing condition. To see how much degradation could be there, just turn volume up for the right ear untill you get same loudness with left ear: a few ticks should be quite tolerable.

[@duprie37]

Wow that's some major hearing loss! Sorry for you.

[@a552bcx]

in order to hear it at 10khz, the decibel (loudness) needs to increase. go see an ear doctor for a real hearing test. the doctor will give you a frequency response graph (frequency on the x-axis vs decibel on the y-axis)

does anyone else hear right side louder than left when it's 250hz? or just might be going crazy in head and/or ears. trying to figure out if it's my left cable or left speaker that's slowly dying a bit or not. my right ear hears worse but tried with both ears and even so if it's my right ear then it should be reverse. youtube has variable sample rate and turning one ear then other for each speaker isn't quite as accurate but damn, is left side quieter or is it just me. cuz when testing some stereo and audio video with music or simple one note one tone sounds it's also either louder on left or somewhat balanced but many of those videos actually just suck for testing bought some dope ass sound card, paired with my dope ass stereo it should be pimpin now. and it is. but was listening to some music and noticed how they liked to mix left channel with quieter melodies and instruments than right. went to check bunch of video tests online and it seems like it might be my speaker or cable on top of that. it stopped at times going very quiet on left since i got sound card cuz it's in sub plug now instead of sound plug so it seems it was pc port problem but cable goes smoothly in left speaker whilst right goes in rough and i can hear more static on left one. makes me think cable or left cable or whole left speaker is bit cucked. prolly from bass resonating of off the desk. can't rly get speaker stands :/

[@boydallen8059]

Listening to this, I found that the frequencies of the left and right were slightly different. At first I thought that it might be my ears, but then I switched my headphones side for side and the difference reversed, which means that it is either the source or the headphone. I am not sure how the same signal would reproduce as different frequency, so that leaves your recording....or am I wrong?

Omg i found the same slightly difference in frequencies from left to right (generally left one has a slightly higher freq.), then i switched my headphones and found the difference didn't switched at all😮 left ear still had a slightly higher pitch frequency than the right one, so i tought it's my ears fault...😅 Do someone else experienced the same?

Note: depending on what KZbin thinks of your link/system/settings … well, on my system, the 16 kHz signal is suppressed (all the lower ones are there fine). [Actually the 16 kHz one _is_ there, but at a much reduced level - about 32 dB down.]

Before you think you're going deaf ... My Sound Pressure Meter shows NO audio output on tones from 2000 MHz upwards. I don't know why that is. It could be the Parametric EQ, it could be my speakers need recapped, it could be the microphone on my SPM app, it could be a lot of things. That's not the point I'm making, I'm saying to check this with an SPM to see if you're actually getting any sound or not even if you don't hear anything. Or do. I have a high frequency hearing loss from a lot of gunfire, explosions and other conflict noises without hearing protection. So I wasn't sure if there was sound I wasn't hearing (and might not anyway) or if there was no sound at all. Turns out that my system is not reproducing those tones at all. I'll work on that and see what I can do to get an SPM reading in those tone ranges and thanks for posting this video. I probably wouldn't have discovered the loss of output without it.
