For months now I’ve been having clear signs of HFHL. Suffering from bad distortion in high frequency sibilance, mainly with female speech. From research I’ve learned sibilance (“sss”, “shh”, " tss") lives around 2-10Khz. This problem has gotten worse lately to the point that I find it hard to enjoy TV/movies. I hear the distortion in real interaction too, but less bothersome.
I’ve learned that this distortion could be caused by HFHL. Sibilance can sound faint to one and piercing distortion to another. Hearing test came clear but I don’t trust it’s efficiency as it checks your ability to hear the frequencies but can’t tell if you hear them louder/distorted.
Over the years I’ve never taken care of my ears. From noise exposure to lack of hygiene. 20 years I’ve been with tinnitus but never drove me mad like this distorted sibilance thing.
I’ve read at times HFHL can be caused by earwax and might be reversible. I’ve always heard not to use cotton swabs in ears so I am going to DR again in a few days.
I know no one can give me a certified answer. But I am just looking for a bit of hope. Could it be that I have this issue because of build up in ears and once the DR sucks it out with his drill, I could hear normally again?
