Aerial low‑frequency hearing in captive and free‑ranging harbour seals (Phoca vitulina) measured using auditory brainstem responses.

Abstract
The hearing sensitivity of 18 free-ranging and 10
captive harbour seals (Phoca vitulina) to aerial sounds was
measured in the presence of typical environmental noise
through auditory brainstem response measurements. A
focus was put on the comparative hearing sensitivity at low
frequencies. Low- and mid-frequency thresholds appeared
to be elevated in both captive and free-ranging seals, but
this is likely due to masking effects and limitations of the
methodology used. The data also showed individual variability
in hearing sensitivity with probable age-related
hearing loss found in two old harbour seals. These results
suggest that the acoustic sensitivity of free-ranging animals
was not negatively affected by the soundscape they experienced
in the wild.
