I suspect I have a hearing loss at 1853/1854 Hz (using headphone) or maybe 1891Hz (using computer loudspeaker), missed by standard audiogram which only tests 125/250/500/1000/2000/4000/8000Hz
I also discovered certain frequency of sound can trigger distinct pattern of T and change the tone of T.
Anyone has the same observation?
