hearing is the greatest gift which nature endowed man.Without hearing it is impossible to full communion with the world around.After all, it is filled with the sounds - the rustle of leaves, dripping sound of the window, roll call of birds.Through hearing we can enjoy the music, to acquire knowledge and to communicate with others.Unfortunately, many who have good hearing, appreciate it less view, but with the help of hearing, we support a much more intimate relationship with the world around us.But people on himself to feel his loss, will confirm that it is perceived and experienced far more seriously than the loss of vision.And do not forget that without hearing we will not have speech.Most of our time is found hearing loss in preschool children.
hearing sensitivity is different, someone is more urgent, someone weaker, but in the absence of any problems, the person hears a whisper at a distance of 6 meters, talking on 6 meters.But lately, a large percentage of the population has problems with auditory
hearing loss - is not only a medical problem, but also social and psychological.Hearing loss is an adult disability in the first place, and the difficulty of communicating with people.Younger children also have yet to study, develop within the team, the choice of profession, so it is particularly important to prevent hearing loss in children.
causes of hearing loss in children of preschool age can be set.First of all hearing loss to distinguish between congenital and acquired.Causes of hearing problems in the age of reason, quite a lot.Consider some of them:
- The ear can get foreign bodies (a variety), or formed cerumen
- Diseases nose and throat can contribute to various inflammations in the ear.Especially dangerous are acute rhinitis, sinusitis, hay fever, the curvature of the nasal septum
- Diseases of the ear membrane and auditory canal
- various injuries of the outer ear and eardrum
- Hearing loss can be a complication of infectious diseases, as well as be the result when somatic diseases suchas diabetes, kidney disease and blood, and etc.
- hearing loss in preschool children because of loud noises, strong vibrations, prolonged use of headphones with a loud sound
- problems with vessels
- Age atrophic changes in the inner ear, as well as birth defects
For proper installation of the diagnosis andproper treatment needed timely diagnosis.It is carried out in different ways, which leads to the prevalence of diseases that lead to hearing problems:
- method of tonal audiometry.With the help of measured hearing thresholds at different frequencies.
- method of speech audiometry.They determine the audibility of speech.
- using a tuning fork.
Modern medical technology can successfully carry out the operation to restore hearing, but such treatment is possible only in diseases caused by otosclerosis, otitis media, purulent inflammation and mechanical damage the eardrum.Regarding the neuro-sensory problems, then medicine is not currently well advanced and the best treatment is ineffective.It is important to diagnose the possible hearing loss in young children the first months of their life, so important period of development of speech and hearing activities.The development of speech in a child with normal hearing doctors distinguish it from a passive period, when the baby perceives sounds, but not yet speaks.On average, this period lasts for the first 18-20 months from the date of his birth.The child hears, learns to distinguish between volume and value of different sounds, "soaks up" the world through its sound.But if a child's hearing threshold is lowered, with time, he ceases to understand the individual elements of the speech, and then completely ceases to respond to them, which inevitably leads to the disappearance of the remaining hearing.
indispensable tool in restoring hearing in the hearing loss in preschool children is a hearing aid.It will enhance the perceived sound of a child, maintaining the proper development of the baby.Over the past few decades, science has made a big step forward in the development of these devices, and modern hearing aids are undoubtedly very different from their predecessors.In our time, a hearing aid is a sophisticated, thin and individually adjustable micro-electronic device that is able to almost completely replace a healthy human ear.Hearing aids come in several forms: BTE, located behind the ear, in-the-are located in the ear canal, they are used in a small hearing loss, intracanal, with a deep-seated in the ear, and the most modern, Open fit (Open Ear), looks almostimperceptible.They all share a microphone, battery, amplifier, volume control and tone, the receiver, which converts the electrical impulses into mechanical vibrations that are available to the human ear.The more sensitive the hearing aid, the greater will be the receiver.
right to choose a hearing aid to help a qualified audiologist and thanks to fine-tuning this instrument beneficial effect on auditory brain activity and contribute to the improvement of natural hearing.We can not postpone the use of a hearing aid, referring to a small age.Early treatment largely is the guarantor of a speedy recovery.
