8 EARCOM Año: 2009 Matrix Sentence Test
Hearing professionals perform audiological tests measuring the speech intelligibility in noise in order to obtain a realistic measure for this kind of hearing disability. Identification of speech recognition threshold in noise and in quiet. Suitable also for profoundly hearing impaired people and cochlear implant users. Possibility of unlimited repetitions of measurements. Special speech simulating noise for best accuracy. No memorizing of test material possible. Adaptive level adjustment.
