| Abstract: | The automated system based on the computer CM-4 and the algorithm for selecting hearing aids are described. From the audiometry data (a hearing threshold, discomfort, etc.) the acoustic characteristics of hearing aids are calculated allowing a low hearing person to improve the speech perception. Then, according to the developed fitting criteria the system selects the required hearing aid from the available set (acoustic characteristics are preliminary loaded into the computer memory). Consequently, an audiologist has the important information on the most adequate hearing aid for a patient along with the data on the unit operating modes and the validate compliance between the rated and computed values. The high efficiency of the system has been demonstrated while selecting hearing aids for low hearing persons in clinical practice, the selection time being considerably reduced. |
