Development of a quick Speech-in-Noise test in “Rioplatense” Spanish, based on Quick -SIN

Horacio E. Cristiani, Valeria Serra, Mijal Guinguis

The development of a quick Speech - in - Noise test, based con Quick SIN, in the Rio de la Plata variant of Spanish is shown, for the measurement of the signal-to-noise ratio. The result was the generation of 8 lists, each of them with 6 sentences, containing 5 keywords that are counted as responses. In the tracks of each list, the phrases are mixed with noise (four-talkers babble with three female speakers and one male) so that each phrase has a signal to noise ratio decreasing, in steps of 5 dB. Three preliminary tests were carried out to select the material to be included in the lists. The first two trials served to select the sentences which are more appropriate to be part of the test while the third test was used to select the best conformation of the lists. The first experiment evaluated the results of the 8 final lists with low pass filtering at 750 Hz, 1400Hz and without filter in normal hearing subjects. The second experiment evaluated the homogeneity of the results of the different lists in groups of normal hearing people and subjects with different levels of hearing impairment.
