A torn eardrum, or tympanic membrane perforation, typically results in conductive hearing loss. This type of deafness occurs when sound waves cannot efficiently travel through the outer and middle ear due to the disruption of the eardrum's normal function. While conductive hearing loss from a torn eardrum can often be temporary and may improve with healing or medical treatment, it can also lead to complications if not properly managed.
The ear drum.
Loud noises can damage the ear drum. Sometimes the cochlea can also be damaged which could cause permanant deafness. Wax in your ear canal can cause temporary deafness

One way would be damaging the ear drum. Another way would be having an infection.
Conductive.
Ear-ache due to infection around the ear-drum: Acute infection of the middle ear, Acute Otitis Media (AOM). And, possibly the most common ear complaint, a build up of ear-wax causing temporary deafness.
Conduction deafness can be a direct result of the fusion of any or all of the three ossicles of the middle ear. If the ossicles cannot transmit sound vibrations properly, then they will not be received by the oval window to be transmitted to the inner ear.

it harms our ear as it is held near the ear.The ear drum cannot resist harsh vibrations which tends to get damaged or even explode if not controlled. This causes deafness.
