A study to assess the feasibility of the use of low frequencies for teaching foreign language to the hearing impaired is described. The subjects were unimpaired Japanese students, aged 18 and 19, in beginning French language study. Recorded sentences translated into English, French, and Mandarin Chinese were combined in various ways and presented to the students through filters eliminating frequencies above 300 Hz. The filters allowed only prosodic features such as rhythm, intonation, pauses, and accentuated versus non-accentuated syllables to be perceived, without phonemes or meaning. Subjects were given some training in low-frequency listening. Results show that perception of the Chinese language was better than that of English or French, but also that in all languages, significant low-frequency perception of prosodic features occurred. This suggests that perception of information transmitted at low frequencies could develop naturally and could perhaps be further developed by external means. (MSE)
