Abstract
We developed a new test of sentence intelligibility in noise in the Czech language. This article demonstrates the results of the influence of different noise types on the sentence intelligibility in persons with a normal hearing ability.
An evaluation of speech recognition can be provided by a presenting of testing material in a sentence form with a presence of competitive noise. This issue has been treated with a lot of interest abroad, however, in the Czech language these audiological tests have not been compiled and used so far.
The babble noise is very often used abroad for its significant interference with speech signal in the time and spectrum domain. The time characteristics of the babble noise are similar to the human voice and therefore it masks more expressively on the central level than the random stable noises.
Test of sentence intelligibility in background noise in the Czech language involves 3 decades of sentences. The sentence context was used from a field of normal life and was phonetic balanced.
We tested listeners with normal hearing. There are more possibilities in the field of speech audiometry in worsened acoustic conditions.
