What's the Longest After a Sudden Loud Noise It's Taken for Ear Fullness/Muffled Hearing to Resolve?

[Damocles]

I'm creating this poll for another user.

Would appreciate all of you who have experienced a sudden acoustic trauma (as in: an explosion, crash, gunshot etc.), letting us know how long after it took for the feeling of muffled hearing and/or ear fullness to disappear?

Please only vote if you have experienced the circumstances outlined above ▲

In the member I'm creating this poll for's particular case, it was the slamming of a lid on some machinery he was standing next to, that created the sensation (along with his newly onset tinnitus).

His tinnitus, ear fullness and muffled hearing are ongoing, 5 weeks from the event, so he'd be grateful to know what the longest anyone who's had these symptoms eventually resolve, has suffered them for.

Many thanks.

@Damocles, thank you.

I had an acoustic trauma this summer. My tinnitus significantly worsened in loudness and changed its pitch.

For now my ear fullness has not gone away completely, however it is a much less frequent sensation than it was days after the trauma. I experience it daily for short periods of time. I also experience sudden muffled hearing and fleeting tinnitus.

EDIT: The aoustic trauma was caused by fireworks explosions.
