In recent years, Internet of Things (IoT) technology for sharing information between people and things and things and things has emerged.

Due to the development of the above IoT technology, there are attempts to introduce it in various industries, and the Internet of Medical Things (IoMT) is one of them.

Medical IoT is a technology that connects information, devices, and systems into one by converting personal lifestyle, disease history, medical use information, and genome information into data.

Representative technologies using the Internet of Medical Things (IoMT) include a technology that can electronically control the heart rate through a patient's biosensor and a technology that can continuously monitor a patient's condition even after the patient is discharged from the hospital. can

On the other hand, the use of hearing aids is increasing due to hearing loss caused by excessive use of earphones or the like or a rapid increase in the population with hearing loss due to aging.

However, it is known that many users do not see the proper effect due to inconvenience in use even if they wear a hearing aid at an appropriate time.

In particular, hearing aid wearers often complain of discomfort that they do not feel the improvement in speech discrimination ability due to sound reverberation or noise. This is a case where a systematic personalized hearing solution course such as training and follow-up management has not been received.

Therefore, in order to obtain the effect of improving hearing by using a hearing aid, it is necessary to select a hearing aid customized for each individual hearing. Furthermore, as the age of the hearing-impaired population is diversifying, external designs ranging from ultra-small to ear-shaped depending on the purpose of use and living environment In particular, since most of the young and old tend to prefer inconspicuous micro hearing aids in consideration of social life, there is a need to develop a hearing aid system that can reflect these points.

The present invention was invented to solve the above conventional problems, and includes a self-fitting hearing aid with a Bluetooth earphone function, a charging cradle with a fitting function and a button structure, and a smart device with a fitting app. A hearing aid system and A fitting method using this is provided.
