Sensory unpleasantness of very-high frequency sound and audible ultrasound
Audible very-high frequency sound (VHFS) and ultrasound (US) have been rated more unpleasant than lower frequency sounds when presented to listeners at similar sensation levels. In this study, seventeen participants rated the sensory unpleasantness of 14-, 16- and 18-kHz tones and a 1-kHz reference tone. Tones were presented at equal subjective loudness levels for each individual, corresponding to levels of 10, 20 and 30 dB SL (sensation level) measured at 1 kHz. Participants were categorised as either “symptomatic” or “asymptomatic” based on self-reported previous symptoms they attributed to exposure to VHFS/US. In both groups, subjective loudness increased more rapidly with sound pressure level for VHFS/US than for the 1-kHz reference tone, consistent with a reduced dynamic range at the higher frequencies. For loudness-matched tones, participants rated VHFS/US more unpleasant than the 1-kHz reference. These results suggest that increased sensory unpleasantness and reduced dynamic range at high frequenci

Abstract
Audible very-high frequency sound (VHFS) and ultrasound (US) have been rated more unpleasant than lower frequency sounds when presented to listeners at similar sensation levels. In this study, seventeen participants rated the sensory unpleasantness of 14-, 16- and 18-kHz tones and a 1-kHz reference tone. Tones were presented at equal subjective loudness levels for each individual, corresponding to levels of 10, 20 and 30 dB SL (sensation level) measured at 1 kHz. Participants were categorised as either “symptomatic” or “asymptomatic” based on self-reported previous symptoms they attributed to exposure to VHFS/US. In both groups, subjective loudness increased more rapidly with sound pressure level for VHFS/US than for the 1-kHz reference tone, consistent with a reduced dynamic range at the higher frequencies. For loudness-matched tones, participants rated VHFS/US more unpleasant than the 1-kHz reference.
