Improving detectability of auditory interfaces for medical alarms through temporal variation in amplitude envelope
Authors' conclusion
Temporal variation in amplitude envelope represents a promising path towards improving auditory interfaces for patient monitoring.
Study context
- Comparison
- Percussive vs flat tones
- Outcome
- Annoyance and detectability
Methodological detailstwo experiments, First experiment: detection of percussive and flat tones at six signal-to-noise ratios during a concurrent speech comprehension task, Second experiment: different participants rated the relative annoyance of the same sounds
- Two experiments
- First experiment: detection of percussive and flat tones at six signal-to-noise ratios during a concurrent speech comprehension task
- Second experiment: different participants rated the relative annoyance of the same sounds
Main finding
As reported in the abstract
- Percussive tones significantly less annoying vs flat tones
- Percussive tones significantly more detectable vs flat tones
Further findings
- Percussive tones did not impair concurrent speech comprehension
