摘要：
The invention relates to medical technology section of Otorhinolaryngology, to the subjective assessment of deafness and the high degree of the patients hearing loss. The technical result, which is aimed at achieving the proposed solution - reducing the time of the main kamertonalnyh experiences in clinical and outpatient medical practice, as well as improving the accuracy of the study of hearing quality in the implementation of screening tests. FIG 1. is a block diagram of the electro-acoustic device. Module wire / wireless communication (1) can be in conjunction with a controlling microprocessor unit, which, in turn, can receive and transmit signals from the signal processor (2) and towards the signal processor (2) used to generate the test tone. Patient response mechanism (3) may include reacting the test of interest digital-to-analog converter (4), attenuator (5) and the power of the analog output signal (6) able to create a strong enough signal to pass it through the headphone port (emitter to study air conduction) (7), either through a bone vibrator (emitter to study bone conduction) (8). New technical solution, compared with the prior art is a radiator for placing bone conduction studies (bone vibrator) directly on the chassis. Figure 2 presents the qualitative comparison timing charts of major kamertonalnyh experiments using the fork (upper diagram) and with the use of the device (the lower diagram). The graph in Figure 2 shows that by using the proposed solution time of the main experiments kamertonalnyh reduced. This is explained exception actions such as re-determination of the hearing threshold (3), the re-excitation and fixing tool (1), (2). Thus through the use of the device a signal which does not fade with time and does not depend on the method of fixing on the patient, simplifies the process of kamertonalnyh experiments.Полезная модель относится к медицинской технике, разделу оториноларингологии, к субъективной оценке глухоты и высокой степени тугоу
