Recent developments in hardware medicine can help people who suffer from various diseases such as acquired or inherited.Sound-electronic device, commonly known popularly called "hearing aid", it allows many people with hearing disabilities to feel more comfortable and convenient, without experiencing the violence of their own inferiority.Due to the current capabilities of hearing aids, hearing can be corrected with special hearing aids that is very important because only an insignificant percentage of hearing loss can be effectively treated by surgery or drugs.
As the latest statistics, around the world about 10% of people have difficulty hearing in certain degree.Since the hearing - is one of the most important components of a normal quality of life, as well as smell, sight, can be very frustrating when for some reason the person is not able to fully hear.Sometimes hearing loss not only creates problems in communication and perception of reality, but also brings a lot of other more serious inconvenien
Hearing loss can occur due to complications of many diseases due to genetic predisposition, because of injuries, etc., but not always, modern hearing aids are able to regain their lost.Nevertheless, the percentage of hearing-impaired people who can help hearing aid, not too small - 90% suffer from hearing loss may forget their help with his problem.Hearing aids can compensate for lost hearing due to natural aging changes in the body, the more important it is that no surgery or medications to fully cope with this problem can not.
People who have certain problems as a result of hearing loss, for whatever reason, are often interested in what modern hearing aids, there are currently on sale.Perhaps many have seen on television the first hearing aids, used in past centuries: they are tubes, narrow on the side where they are inserted into the ear, and the other wide.
Thus, people have tried to improve the audibility, but the assurances of modern researchers, the effectiveness of this tool was not so high.Already in the 20th century there were prototypes of modern appliances, which also were far from ideal.The fact is that hearing loss occurring at each person differently, so modern hearing aids should take into account this factor, which had been quite difficult to achieve.In these first prototypes of the modern apparatus was not special settings, so the excess noise bring their owners great discomfort.
Because hearing loss in humans may be different, modern hearing aids just had to take this into account in its design, so they compensate the person at the hearing of necessary frequencies.Another important aspect of enabling people with hearing impairment feel more comfortable is the fact that modern hearing aids are practically invisible to others.The difference current hearing devices consists in the methods of processing of sounds.
most easy-to-use hearing aids are analog version.They do not have a wide range of different settings, but can be very useful as a first aid, without the ability to turn the art.More advanced devices in this area are digital hearing devices, they are more flexible configuration, allowing each user to customize them as per requirement.In digital devices contain an embedded chip, allowing to process audio signals with such devices often have different programming options.
Hearing of the latest generation is quite able to compensate for the partial loss of hearing, and they have truly wonderful capabilities, namely:
A) Compensate violation perception of frequency and volume
B) Provides speech understanding in various situationsincluding, when extraneous noise in group conversations, in silence, etc.
in) allows to perceive sounds in a natural way: a foreign language, their own voice, music or nature sounds.
D) They automatically adjust the volume, keeping it at a comfortable level of perception.
D) adapts itself to different acoustic nuances.In particular, you can safely talk on the phone, to perceive danger signals.
E) Consume little energy and operate reliably.
Of course, even the most modern, advanced hearing aids are not able to cure deafness and hearing loss, there are no miracles, but this indispensable tool capable of much better opportunity to communicate, easy to adapt to society.Typically, the hearing aid has a traditional structure consisting of the necessary elements.These include a microphone, an amplifier, etc.Types of hearing aids are also different, isolated BTE models, which are located behind the ear, and complemented by an in-liner.In turn, in-the types of hearing aids are placed directly in the ear and are made taking into account the individual characteristics, corresponding to the shape of the ear canal.
