Hello This is not an uncommon problem after exposure to loud sounds and is known as a temporary threshold shift It is basically your ear telling you please don t shout , otherwise I will stop listening Tinnitus ( or the humming sound you are getting ) usually lasts for a few days, but if the ear is recurrently exposed to loud sounds, these changes may be permanent 10 days is a lot , but I would still allow your body to slowly re - adapt Medical treatment is usually not helpful , BUT , you should avoid any further exposure to loud sounds Persistant exposure to loud sounds may result in permanent damage to the sensitive inner ear , and may even cause permanent deafness
