Speech processing in noise and the ability to differentiate sounds by musicians and nonmusicians.

This study aimed to investigate the perception and processing of speech in noise among musicians and nonmusicians. The study included 60 participants, ages 25-35, divided equally between musicians with formal training and nonmusicians without structured musical experience. Participants' hearing levels were assessed through pure tone audiometry to confirm normal hearing function. During the study, all participants were required to listen to audio recordings with articulation tables overlaid with white noise. The results showed that the Articulation Index (AI) for recognizing stop consonants was 8.0 out of 10 for musicians and 6.5 for nonmusicians. A 0-10 scale was used to determine the AI score values, which were 7.5 for musicians and 6.0 for nonmusicians. Higher scores on this scale indicate better speech perception in noisy environments. It measures overall intelligibility. The final %ALcons for listening to stop consonants was 21% for musicians and 25% for nonmusicians. During listening to fricative consonants, this indicator was 33% for musicians and 37% for nonmusicians. These findings indicate that musicians demonstrate better speech perception in noise. While these results suggest potential applications of musical training for auditory rehabilitation (e.g., in cases like Wernicke's aphasia), further longitudinal research is required to establish causation.
