Superior ultra-audiometric hearing: a new type of hearing loss which correlates highly with unusually good speech in the "profoundly deaf".

This paper reports 42 severely-to-profoundly deaf subjects, 6 of whom have better hearing in the range of 8 to 14 kHz than below 8 kHz. Data on speech capabilities in these six subjects suggest that this ultra-audiometric range may contribute to their speech comprehension and control.
