What is it about?
In a robust laboratory setting, we determined that it is safe for auditory alarms to be softer than background noise, and preserve clinician performance

Why is it important?
With loud alarms, patients cannot sleep, and clinicians may suffer fatigue and auditory masking.
Perspectives
With ongoing research on auditory alarm design, this is a first step to parse out aspects of sound (the signal to noise ratio), and understand that spectra of sound is important for perception.
