STUDY OF PHONETIC FACTORS IN RELATION TO ACCURACY OF TRANSMISSION OF WORDS IN AIRPLANE NOISE.

Presents a study of phonetic factors in relation to accuracy of transmission of words in airplane noise. Statistical analysis of intelligibility test records made by aviation cadets; Study of preservation-in-error tendencies of speech sounds; Differences of sounds in words from sounds in nonsense syllables; Intelligibility in noise understood by the study of the preservation-in-error capacities of sounds; Need for increasing studies on the data on preservation-in-error values of sounds.
