Overview

Analysis reveals detection thresholds for airborne sounds in marine mammals, indicating potential noise effects in Arctic environments.

Key Points

  • Detection thresholds were established for four frequencies and exposure conditions in marine mammals, indicating air and noise interaction.
  • Findings show the impact of ambient noise on 50% detection thresholds across varied frequencies from 0.04 to 51.2 kHz.
  • Assessment measured auditory capacities of one adult bearded seal, highlighting unique auditory sensitivities differing from typical expectations.
  • Results underscore potential noise effects on seals in changing Arctic soundscapes, necessitating further research on marine mammal responses.
