Those who have conductive hearing loss can often use any one of the better aids with good results. Patients with otosclerosis will probably need the bone-conduction type of instrument. Those with sensorineural hearing loss (caused by injury to the vestibulocochlear nerve), or a mixed type, may have more trouble selecting a suitable hearing aid and may get less satisfactory results.
Those wearing a hearing aid for the first time should have special training in its proper use. A hearing aid picks up and amplifies all sounds in the vicinity. Often a person whose hearing has declined gradually will have lost the facility to ignore background noises. When one first tries a hearing aid, one's ears will be assaulted by the sounds of passing cars, of doors slamming, of telephones ringing. Training in how to filter out these noises and concentrate on the essential is necessary if the person is to get good results from the hearing aid. For best results, this should be combined with lessons in lipreading.
A cochlear implant can help profoundly deaf persons recognize and interpret various sounds. It does not restore hearing but can improve the quality of life for the deaf.
hearingAudiology A series of events in which sound waves in air are converted to electrical signals that are sent as nerve impulses to the brain where they are interpreted
Hearing acuity can be determined by measuring the distance at which a person can hear a certain sound such as a water tick, by using audiometers, and by bone conduction. In audiometers, electrically produced sounds are conveyed by wires to a receiver applied to the subject's ear. Intensity and pitch of sound can be altered and are indicated on the dials. Results are plotted on a graph known as an audiogram. In bone conduction tests, a device such as a tuning fork or an apparatus that converts an electric current into mechanical vibrations is applied to the skull. This is of value in distinguishing between perceptive and conductive deafness. Conductive hearing loss may be diagnosed with the Weber test. Having the patient hum produces no difference in the sound heard if hearing is normal. The sound is perceived as louder in the ear with conductive hearing loss.
earthe structures concerned with hearing and also with balance and posture. (1) The external ear leads to the tympanic membrane (eardrum) which separates it from (2) the middle ear, where the chain of 'ossicles' transmits sound vibrations to (3) the inner ear containing the sense organs for hearing (the cochlea) and for movements of the head (the vestibular apparatus). Afferents from these pass into the brain in the auditory nerve . The cavity of the middle ear is connected to the pharynx via the Eustachian tube.
Patient discussion about hearing
Q. I would like to hear from you. I'm searching help for my son, who is suffering from Autism. I was wondering if any of the parents of children with Autism have noticed any changes when they change their children eating habits. If so, have you noticed any significance in the improvement of your child's behavior? I would like to hear from you.
Q. How do I make him listen? Hi, My kid is so irrespective and just we have diagnosed him with ADHD. He is just seven years old and makes fun of his friends. It seems that they do not like him.
