The objective of this study was to develop and evaluate the Polish digit triplet test for speech intelligibility screening. The first part of the paper deals with the preparation of the speech material, the recording procedure and a listening experiment. In this part, triplet-specific intelligibility functions for 160 different digit complexes were(More)
The aim of this study was to develop Polish sentence tests for accurate measuring of speech intelligibility in masking interfering noise. Two sets of sentence lists have been developed. The first set was composed of 25 lists and was used for sentence intelligibility scoring. The second set was composed of 22 lists and was used for word intelligibility(More)
OBJECTIVE To develop the Russian matrix sentence test for speech intelligibility measurements in noise. DESIGN Test development included recordings, optimization of speech material, and evaluation to investigate the equivalency of the test lists and training. For each of the 500 test items, the speech intelligibility function, speech reception threshold(More)
The speech intelligibility for different configurations of a target signal (speech) and masker (babble noise) in a horizontal and a median plane was investigated. The sources were placed at the front, in the back or in the right hand side (at different angular configurations) of a dummy head. The speech signals were presented to listeners via headphones at(More)
The purpose of this study was to determine the binaurally perceived modulation depth (m) of the low rate amplitude modulated (AM) signals, under conditions of their dichotic presentation, i.e., when the AM signals presented to the left and the right ear had different modulation depths. The modulation depth was determined as a point of subjective equality(More)
