Material and methods. 10 people with normal hearing and 28 users of hearing aids with moderate to severe sensorineural hearing loss were involved in the study. RuMatrix test both in quiet and in noise was performed in a free sound field. All patients filled in the COSI questionnaire. Results. The hearing impaired patients were divided into two subgroups: the 1st with high and the 2nd with low hearing aid benefit, according to the COSI questionnaire. In the 1st subgroup, the threshold for the sentence intelligibility in quiet was 34.9 ± 6.4 dB SPL, and in noise -3.3 ± 1.4 dB SNR, in the 2nd subgroup 41.7 ± 11.5 dB SPL and 0.15 ± 3.45 dB SNR, respectively. The significant difference between the data of both subgroups and the norm was registered (p <0.05). Conclusion. High informative value of sentence speech audiometry in a free sound field for assessment of the hearing aid fitting benefit is shown. The higher sensitivity of testing in the noise condition compared with the studies in quiet was revealed.speech audiometryfree sound fieldRussian matrix sentence testsensorineural hearing losshearing aidsречевая аудиометриясвободное звуковое полерусский матриксный фразовый тестсенсоневральная тугоухостьслуховые аппараты[Бобошко М.Ю., Риехакайнен Е.И.
