TABLE I.

Description of hearing-impaired subjects in terms of sex, audiometric thresholds in dB HL in left and right ears at six frequencies, pure-tone average (PTA) over five octave frequencies between 250 and 4000 Hz, history/etiology of loss, and age in years. For each subject, the test ear is denoted by bold lettering. The final two columns provide information about the speech presentation level (prior to NAL amplification) and the SNR used in the consonant testing for each subject.
