Localization of novel reduced-annoyance audio interface sounds

Foley et al. [JASA 151, 3189–3196 (2022)] have demonstrated that annoyance of auditory interface sounds can be reduced both by shortening the duration of upper harmonics and by applying percussive rather than flat amplitude envelopes. However, sounds in that study had a maximum frequency of 2400 Hz, which would likely affect localization based on spectral cues. In a setting with multiple interface devices (e.g., a multi-patient hospital ward), …
