Deformity of the outer ear or middle ear. For example by the insertion of grommets or tubes into the eardrum. Persistent middle ear conditions can be helped with the use of a hearing aid. The aid compensates for the loss of loudness Effective management of a conductive hearing loss will allow the development of good spoken communication skills. Sensori-neural hearing loss occurs when there is a problem in the inner ear.
Sound travels normally through the outer and middle ear.
However, damage to the hearing nerves of the inner ear prevents the sound reaching the brain as a clear signal. These losses cause a loss of loudness and can also affect the clarity of the signal. Sensori-neural hearing losses are described by severity, varying from mild to profound. However, in many cases the cause of a sensori-neural hearing loss remains unknown. Sensori-neural hearing losses cannot be cured by medication or surgery.
