Conductive hearing loss can be recognized by a number of salient features, including the fact that loss of hearing acuity rarely exceeds 60 dB and the individual hears well at all frequency levels. Finally, the individual hears better by bone conduction (through the bones of the head) than by air conduction (Emerick 145).
If Mr. Brown should found to be suffering from a hearing loss in this decibel range added to the key finding of equal hearing loss in all frequencies and good bone-conduction, a diagnosis of conductive hearing loss would most likely be in order. How to treat this type of hearing loss depends on its cause. Excessive wax should be removed from the ear; the same treatment is of course recommended for any foreign objects. (Foreign objects' interfering with hearing may be an especial problem with children, who seem to delight in introducing forbidden objects into their ears.) Congenital deformities or the bone fusion resulting from otosclerosis may require surgery. Conductive hearing loss due to enlarged tonsils or adenoids, middle-ear fluid or tumors of the auditory nerve may also require surgical intervention.
Given Mr. Brown's age, it seems likely that his difficulty may well be a conductive hearing loss since he is not yet old enough to be considered an obvious candidate for age-induced hearing loss or presbycusis. However, if he is consistently bombarded with loud noises – ranging in origin from rock bands to industrial machinery – he may well b
