Razlika u razini razumljivosti CCV i CVC forme logatoma ispitivana u dva zatvorena prostora

Logatome listening tests are a standard method for speech intelligibility level assessment in closed spaces. The main focus of this work is to highlight the difference between CCV (consonant-consonant-vocal) and CVC (consonant-vocal-consonant) logatome form intelligibility levels as a function of speaker-listener distance and room acoustic properties, namely the reverberation time. In accordance with that, two closed spaces with different acoustic properties have been examined using logatome tests. The percentages of correctly heard CCV and CVC types of logatomes for three different source-listener distances are presented for each of the enclosures. Following that, female and male participants' CCV and CVC results are shown separately and compared to each other for each of the six cases. In the end of the paper, the correlation between the percentage of correctly heard logatomes for each of two logatome types, the acoustic parameters of closed space, i.e. the impulse response and reverberation time, and the masking effects of human hearing system is discussed in detail and the conclusions are drawn.
