These results are not consistent with the concept of softness imperception. This relationship held for SLs up to 4–10 dB, depending on the subject. When the fixed tone was presented at a very low SL in an ear (or at a frequency) where there was hearing impairment, it was matched by a tone with approximately the same SL in an ear (or at a frequency) where hearing was normal (e.g., 2 dB SL matched 2 dB SL). Loudness matching was possible for sensation levels (SLs) as low as 2 dB. For subjects with sloping hearing loss, matches were obtained between tones at two frequencies, one where the absolute threshold was nearly normal and one where there was a moderate hearing loss. For subjects with asymmetrical hearing loss, matches were obtained for a single frequency across ears. This has been called “softness imperception.” To evaluate this idea, loudness-matching functions were obtained using tones at very low sensation levels. Buus and Florentine have proposed that loudness recruitment in cases of cochlear hearing loss is caused partly by an abnormally large loudness at absolute threshold.
