Temporary threshold shift (TTS) in odontocetes in responses to multiple air gun impluses

Open Access Report 2013

Final Report

Finneran, J., Schlundt, C., Branstetter, B., Trickey, J. et al.
To investigate the auditory effects of multiple underwater impulses, auditory thresholds were measured in bottlenose dolphins before and after exposure to a series of impulses produced by a seismic air gun. The pre- and post-exposure hearing thresholds were compared to determine the amount of temporary hearing loss, called a temporary threshold shift (TTS), as a function of exposure conditions.
