It is widely believed that extended high frequencies (EHF) (frequencies ≥8 kHz) have little role for speech perception, being beyond the traditional “speech bandwidth.” This view may be due, in part, to the mixed findings from studies that have examined whether there are benefits with audibility of high-frequency bands, some of which have included energy at EHFs ( Stelmachowicz et al., 2001 33. For humans, the frequency range of hearing extends to approximately 20 kHz.
