Abstract(in English) Hearing aid evaluation system which consists of four loud speakers put out surrounding noise, a front center loud speaker put out testing words, and a dummy head (DH) in the center, was studied. In order to simulate noisy surroundings, the multi-talker (MULT) noise, the simulated electric-train (SELT) noise, and the simulated multi-talker (SMULT) noise were tested in a small hall and in an anechoic room. Fifty testing words with three syllables for each were put out through the front center loud speaker, the DH was rotated at the interval of 45 degrees, and the mixed sound of testing words and surrounding noise was recorded into the DAT through the DH for eight directions. Later, effectiveness evaluation was done by measuring the directional intelligibility by means of the hearing test. As the experimental result, it has been clear that the effectiveness evaluation of hearing aids is possible under the following conditions; surrounding noise should be non-correlated MULT noise, SNR should be 0[dB] or -5[dB], hearing test should be done by using the open type head phone, and repeated hearing should be allowed.
