Popis: | Studied in the work was human perception of acoustic signals changing in amplitude on the background of production and hearing of syllables composed, from the ontogenetic viewpoint, of the “earliest” and the “latest” consonants and vowels —[pa] and [ly], as well as on the background of noise. It was shown that on the background of the syllable pronunciation their recognition occurred at the same rate; however, the number of mistakes with the syllable [ly] was statistically significantly greater than with the syllable [pa]. According to the data of paired comparison and dispersion analysis the differences at recognition of external stimuli on the background of: hearing [pa] — pronunciation [ly]; hearing [ly] — pronunciation [pa]; hearing [ly] — pronunciation [ly] are statistically significant. The most difficult task turned out to be the task of signal recognition on the background of isolated articulation, i.e., reproduction without voice. When evaluating sound stimuli on the background of noise, the correctness of signal recognition was more affected by masking as compared to the time of reaction. The results of signal perception on the background of the wideband noise differ qualitatively and quantitatively from the data of recognition both at intensive verbal activity and at passive hearing of speech. |
