This fully depends on what type of hearing loss you have. There are 2 types of hearing loss:
Conductive hearing loss is usually caused by an obstruction in the ear canal, such as swelling due to an ear infection, or a benign tumour. If your Hearing Care Professional determines your hearing loss as conductive, your hearing may return to normal once the obstruction has been removed. If it does not, you may benefit from wearing a hearing aid.
Sensorineural hearing loss is caused by damage to the sensory hair cells of the inner ear. This damage can be caused by exposure to loud noise, illness, side effects of certain medications, injury, or age. If your Hearing Care Professional determines your hearing loss as sensorineural, you may benefit from wearing a hearing aid. Presbycusis, generally a subset of sensorineural hearing loss, occurs in most individuals as they age. This condition is common, and can often be improved by hearing aids.
