A digital hearing aid the control method and the mobile communication terminal using a mobile communication terminal and a digital hearing aid

It relates to a wireless digital hearing aid using a digital hearing aid and interoperable mobile communication terminal and a mobile communication terminal. According to a preferred embodiment of the invention, the cellular mobile communication terminals and cooperating with the digital hearing aid user when the hearing aid is driven amplification is performed to fit the hearing characteristic of the user. That is, passing the user's auditory information to a terminal controls the amplification gain to the terminal measures the signal environment to prevent audible impact (acoustic shock). In addition, the terminal calculates the environmental profile by analyzing the acoustic characteristic information of the user transmitted from the surrounding signal with a hearing aid they are measured, and by passing them to the hearing aid to automatically adjust the degree of non-linear amplifier according to the user environment. A digital hearing aid, a mobile communication terminal, fitting, hearing protection
