Although genetically variable, it is a normal concomitant of ageing and is distinct from hearing loss caused by noise exposure, toxins, or disease agents. [1]
The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork.
