God created us in the best of the calendar, and blessed us with a lot of blessings in our bodies that help us to enjoy a normal life, healthy and sound. One of the most important things that God has blessed on man is the grace of the five senses, hearing, sight, smell, taste, and touch. In our article, we will talk about the most important emotion on which a person depends so much on his normal normal life: hearing.
The sense of hearing is one of the five most important senses that God has blessed us with, since the sense of hearing depends on the human in his life everything he performs and practiced, through hearing the human learn speech and speech, and learn language skills and communication skills with others, and hearing helps to know Sounds and analysis, an alarm at the risk. This sense depends on the person’s ability to be sensitive to vibrations and sound vibrations through the body’s hearing system, the ear, where these fluctuations and vibrations of the ear “hearing system” to reach the brain, which analyzes sounds and understanding.
As for the mechanism of action of this sense, the sound waves and oscillations that reach the ear, “Flint” collected, and passes to the external audio channel and then move to the “drum”, where the drum transforms and pass the vibrations to the “hammer” and then to “Anvil And then to the “cochlea”, and then to the “cochlea”, resulting in a vibration in the audio channel and the felicitous, we generate a set of vibrations transmitted to the brain through the nerve auditory nerve, and the brain analyzes these sounds that reach us as we hear .
Some people may have hearing problems, which is scientifically termed “auditory contamination”, a result of either hearing impairment, poor concentration, or high blood pressure, nervous stress, Hearing aids in the individual through the device, “Edometer”, a device that performs electrical tests audio, provides the examiner rates and accurate measurements of the rate of hearing in the person.
For those with hearing impairment problems, over the past century and years, many hearing aids have been developed that help the hearing impaired to improve their hearing ability, through medical speakers and the development of many techniques in this field, or through cochlear implants Helps to be alternative in some cases to the original cochlear device in the ear device in the human body in case of hearing impairment due to defect in the work of the cochlea itself. One of the most famous and specialized companies in this field is the Swiss company Funak, Oticon and others.
