The main ear examination is done with the otoscope microscope (otomicroscopy).
The main test for the diagnosis of hearing problems is audiometry, which requires headphones, speakers or a bone vibrator through which the sound reaches the patient. For its execution a soundproof booth is needed, which the patient enters. The most conventional tests are tonal audiometry, suprathreshold and verbal.
Another important test is Tympanometry, which complements the above in order to find out the location of the hearing impairment and it is complemented by the study of the stapedial reflexes.
The Otoacoustic Emissions and Auditory Evoked Potentials Brainstem tests are objective tests. The first is used for the screening for congenital hearing loss or universal screening for hearing loss and the second is used for the diagnosis of deafness in infants or small children.
