AbstractThis paper reports on testing done to more accurately define the needs of young listeners in actual classroom conditions. improve knowledge about how signal-to-noise ratios (S/N) needs vary with the age of listeners. The WIPI (Word Intelligibility by Picture Identification) test was used in classrooms to assess the word recognition performance of grade 1, 3 and 6 schoolchildren for varied speech-to-noise ratios (S/N). The effects of age from the classroom tests were compared with baseline data obtained using young adults in simulated sound fields. The young adults completed the WIPI test, a Rhyme test, and a Listening Difficulty test in the simulated sound fields to make it possible to compare the results of these three test procedures and to act as baseline data for comparison with the classroom results of the children.
