Resting-associated vocalization emitted by captive Asian house shrews (Suncus murinus): acoustic structure and variability in an unusual mammalian vocalization.

The average duration of single vocalizations was 65±47 ms, with “partially noisy” vocalizations being, on average, about twice as long (115.5±92.3 ms) as “tonal with low click” vocalizations (57.5±29.0 ms), a result that was nevertheless only marginally significant ( t 14 = 2.70, p = 0.017).
