Method for compensating for hearing loss in a telephone system and in a mobile telephone apparatus

Abstract

The method makes it possible to extend functional possibilities, and to increase sound quality and the intelligibility of speech in mobile telephone apparatuses and communication systems for hearing-impaired subscribers. The mentioned technical result is achieved in that, in the method, personalized audio signals (A) for hearing-impaired users are generated on the basis of attributes thereof received from audiograms - frequency characteristics of the hearing of the hearing-impaired user stored in a database on the server of the communications network and linked to the telephone numbers of hearing-impaired users. A is processed on the server in a broadband frequency range on the basis of attributes of the hearing of the hearing-impaired user, the power of the processed audio signals is adjusted according to the attributes of the hearing-impaired user, and the adjusted personalized audio signals are transmitted from the communication server to the telephone apparatuses of the hearing-impaired users. The communications network used is a cellular network, and the telephone apparatus used is a mobile telephone apparatus (MTA). A mode which combines the function of a mobile telephone and of a hearing device is implemented.

Description

technical field [0001] The present invention relates to computer engineering and telecommunications systems and may be used to improve the intelligibility of hearing impaired users (with sensorineural hearing loss). Background technique [0002] People with sensorineural hearing loss often have an elevated perception level of sound information that prevents them from hearing low-intensity sounds. However, loud sound perception is usually at the same level as normal people. Perceived hearing loss thresholds were frequency dependent and were determined for each patient at specified frequencies (200; 500; 1,000; 2,000; 3,000; 4,000 and 6,000 Hz) using a clear tone signal. [0003] The task of improving the intelligibility of the hearing-impaired population involves bringing the dynamic range of speech and everyday sounds within the dynamic range of the limited impaired hearing. This method of compressing the dynamic range represents the response of the audible range signal to...

[0025] Failure to create a personalized audio signal that enables the user to listen to audio files, radio broadcasts, etc.;

[0026] While simultaneously receiving audio signals from the speakers of various devices, the user is unable to obtain the personalized signal he needs to communicate with interlocutors located in close proximity;

[0027] While listening to an audio signal from a multimedia device, a hearing-impaired person cannot simultaneously maintain a conversation with a user of a telecommunication network and an interlocutor located in close proximity;

[0028] Except for automatic telephone exchanges, computer equipment containing processors, random access memory, long-term storage units, and equipment providing communication network access cannot be used as network servers;

[0029] Users of such devices cannot use various modes according to their preferences, such as telephone conversations, personal communication with interlocutors, receiving audio signals from speakers of different devices
