How to Diagnose / Measure Hidden Hearing Loss?

Hi all,

I'm 28M with tinnitus in my right ear after microsuction / syringing 3 weeks ago.

Audiogram was normal (0-10 dB) for all frequencies up to 8 kHz, and no anomalies in the noise-in-speech test or tympanometry.

Despite these results, I have a perceived loss in my right ear (I can tell my left ear is crisper / louder when blocking alternate ears watching TV).

So I think I have ‘hidden’ hearing loss relating to my right ear which is causing the tinnitus in an attempt to compensate.

I have another hearing test and tinnitus consult with an audiologist on Wednesday - wondering what tests I can ask for / can ask them in an attempt to quantify this loss in my right ear? The noise-in-speech is obviously a very blunt tool. I’ll be asking for an extended range audiogram and mention my tinnitus seems to be about 4 kHz.

Thank you.
