Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain muffled hearing after sudden exposure to loud sound can lead to
Acoustic Trauma to the ear..
It can lead to perforation of the
eardrum as well as there can also be damaged to hair cells present in the
inner ear leading to muffled hearing or can also cause complete
hearing loss..
You should consult an Otolayngologist and get evaluated and an Otoscopic examination can be diagnostic..
Many a times the patients start recovering within 48 to 72 hours after taking
steroids, antibiotics and decongestants..
In case if the injury is severe and there is large perforation of the ear drum surgical correction may be advised..
Hope this information helps..
Thanks and regards.
