Audiometric data for hearing-impaired listeners (HI1–HI7). The ear tested is associated with the entries in bold. The %Sp column refers to speech recognition for monosyllabic words in quiet with presentation level approximately 30 dB above the speech recognition threshold for spondee words. “NR” indicates that the threshold was above the limits of audiometric testing and “DNT” indicates that the test was not performed.
