Hyperviscosity syndromes such as Von Waldenstroms macroglobulinemia are another rare cause. Superficial siderosis, due to CNS bleeding, can cause a slowly progressive sensorineural hearing loss as well as cerebellar or vestibular disturbances. Even if there are different types of hearing loss we need to think about the fact that in most cases there are solutions that can help us. In order to understand the various treatment options, it is important to understand some of the anatomy and physiology of the ear. The ear is divided into three main parts, the outer ear, the middle ear, and the inner ear.A The outer ear consists of the auricle and ear canal and eardrum. Tympanic membrane perforation: A large hole in the ear drum, like a hole in a pocket, allows some sound energy to escape and be wasted. Otosclerosis: Stiffening of the stirrups bone, like arthritis restricts transmission of sound. Acoustic neuroma: This and other brain tumors can cause pressure on the hearing nerve and thus disrupt transmission of sound. Sudden onset sensorineural hearing loss: This is a type of nerve hearing loss that occurs rapidly over the course of hours to days because of damage to the inner ear hair cells.
On the other hand, sensorineural hearing loss is usuallyA irreversibleA -- with only a few exceptions. This is a really common problem noticed in our inner ear and basically means that the instruments inside our inner ear have suffered from some sort of damage. Superficial siderosis can be easily diagnosed on MRI from the characteristic hypointense areas where iron has been deposited. Radiation to the ear is often associated with a chronic, progressive hearing deterioration (Wang et al, 2004).
In the event that the ears are perfect and we cannot follow conversations this remains the only solution possible. The hearing aids are really useful and can be used by most people that suffer from moderate to mild hearing loss. If you have hearing loss you may not be aware of it, especially if it has developed over time.


The hearing pathway is made up of five main divisions: the external ear, the middle ear, the inner ear, the auditory nerve and the brain. Oftentimes, it is only when we lose this special gift, that we realize its importance.A In the early days, there was not very much to be done about hearing loss. Also, in the hearing process we also see that the brain has a very important role in interpreting the information that is offered by the ears. These instruments are important because they are responsible for sending waves to our brain. The hearing process begins when sound waves enter the outer ear and travel through the ear canal to the ear drum, causing the eardrum to vibrate. These three hearing bones are connected in such a way that using mechanical leverage, they are able to amplify sounds and transmit the vibrations to the inner ear.A The inner ear is completely encased in bone and consists of a cochlea and a labyrinth.
Hearing aids consist of tiny microphones and speakers that boosts the volume of incoming sounds.
We can say that there are 4 types of hearing loss even if each will also have different sub categories. Also, the audiologist will not do much and there is a need to go for use of the services offered by neurologists. For example, they may notice that you are having difficulty hearing what people are saying, especially when many people are talking at the same time or in the presence of background noise. Before the industrial revolution, crude devices shaped like trumpets were developed to collect and funnel sound into the ear. For instance, if hair cells at the base of the spiral cochlea grow weak and die, a high frequency nerve hearing loss will occur.
There are many types and configurations of hearing aids, each of which has its own advantages and disadvantages. It is highly recommended that you immediately consult audiologists as soon as you notice that you are losing hearing so that they can check what problems you are faced with. The sound waves are amplified as they are passed from the eardrum and malleus to the next two bones of hearing, the incus and stapes. That represented the birth of the hearing aid.A As technology progressed, it was discovered that there were different types of hearing loss that could be treated in a variety of ways.


Problems that cause conductive hearing loss usually reside at the external ear or middle ear.
There is also the possibility to find objects that are blocking the sounds especially when dealing with toddlers and infants. In this case the only solution to treat the problem is the use of hearing aids because the hearing will be lost forever and the process cannot be reversed. Inside the cochlea, the vibrations transmitted by the hearing bones move little hair cells. The following are some causes for sensorineural hearing loss.A Presbycusis -- a fancy name for age-related hearing loss. Digital hearing aids can give clearer sounds, however they are usually more expensive.A Wearing hearing aids is much like wearing glasses. The inner ear is made up of a snail-shaped chamber called the cochlea, which is filled with fluid and lined with thousands of tiny hair cells which are attached to the auditory nerve. High-pitched sounds stimulate high-pitched hair cells that are located at the base of the spiral.
Noise induced hearing loss: loud noises enter the cochlea near the base of the spiral and damage these cells first. Infections are an extra cause that needs to be taken into account but in this case antibiotics will usually solve. The movement of the fluid stimulates the hair cells, which then activate the nerve endings. These specialized hair cells, in turn, fire off nerve impulses that the brain interprets as high-pitched sounds.
The complexity of features and circuitry within the hearing instruments determines the cost of the device.
