Finnish speech in noise test: long-term reproducibility

A computerized adaptive Finnish speech in noise test was developed recently. As part of the test's evaluation process the long-term stability of speech recognition threshold in noise (SRTN) was determined. The non-operated ears of 164 stapes surgery patients were assessed preoperatively and at 1, 7 and 19 months postoperatively. Short-term and long-term repeatability were equal. The absolute intraindividual differences were 1.5 dB on average.
