Listening means not only receive and understand sounds and tones. It allows us to capture our environment more fully to orient us to communicate with our fellow men. It gives us security, it warns or calms us, it affects our thinking and feeling important.
Who hears poorly, often feels inhibited or precluded. He takes acoustic signals only attenuated, changed or partly no longer true. Often comes to hearing loss (medically hypoacusis) a hearing impairment (Dysakusis). Sufferers do not understand properly what her interlocutor says. Words and phrases come to be distorted.
First indications of possible causes of hearing loss
A hearing disorder can be congenital or develop through both internal and external influences. Depending on the cause it appears suddenly and goes over again or it sets a slinky, with time more and to permanent hearing problem. It affects one or both ears. The type and shape as deafness manifests itself give, together with other accompanying symptoms already indications of possible triggers.
In a sudden loss of hearing, for example, the hearing loss is acute one in one ear. A feeling of pressure in the ear, tinnitus and vertigo happen. For hearing, accompanied by ear pain, fever, fatigue, a middle ear or ear canal inflammation may be responsible. The diseased part of the ear is then often red, swollen and over-heated. Sometimes, however, sees only the doctor in the study such signs of inflammation. In addition, coming out of the ear (pus) discharge.
An over loud bang or explosion can damage the hearing organ immediately. A Bang explosion or trauma causes a sharp ear pain with sudden hearing loss produced up to deafness.
People who are exposed to prolonged periods of noise, and without adequate protection and necessary breaks, often develop a hearing loss. It sets usually is insidious and may be associated with tinnitus. Noise-induced hearing leads the list of recognized occupational illnesses in Germany.
A presbycusis is usually also a slowly. Over several years the hearing diminishes steadily. It is often difficult relatives and friends at first that the person begins worse to hear.
In some diseases, such as typically used in the Ménière’s disease, in addition to the hearing organ in the inner ear, the neighboring equilibrium organ is attacked. The patients then suffer not only hearing but also dizziness and tinnitus.
Forms of hearing
The sensitive end of the hearing in the ear and in the neural pathways of the brain can be affected in many ways. Often all you need a thick Ohrschmalzpfropf to impede the transmission of sound signals and trigger a temporary hearing loss (more on this in the chapter “How we hear”).
Depending on which ear portion runs out of hearing impairment, doctors distinguish two main types of hearing loss:
Conductive hearing loss: hinder disorders or diseases in the outer or middle ear or distort the hearing specialist transmission of sound waves.
It is typical that the affected high as low tones only hear from a certain volume, but still good to understand what is being said.
Sensorineural hearing loss: Here the hearing organ to the sensory cells in the inner ear or the auditory nerve are often permanently damaged, so that the sound signals not properly reach the auditory system of the brain. The disorder may also be in the brain itself. Typical hearing loss include presbycusis and noise induced hearing loss.
Typically, do people with a sensorineural hearing loss soft sounds, here especially at first the high notes, no longer. The volume sensitivity is increased. Normal loud sounds feel those affected as softly, but loud sounds as unpleasantly loud. They also have problems understanding speech properly. Background noise they experience as disturbing. This makes it difficult especially to follow conversations with several people.
It is estimated that 17 to 20 million German from reduced hearing, and the number continues to rise, especially among young people. Most of the chronically hard of hearing have an inner ear disorder. This may also be associated with a common middle ear hearing loss (conductive hearing loss).
