Ketten, D.R. de Jong, C.A.F. Lam, F.P.A. Kastelein, R.A. Publication year 2020 Abstract This report describes the results of two separate IOGP JIP-funded projects (I) and (II), both aimed at studying Temporary Threshold Shift (TTS) in harbor porpoises (Phocoena phocoena) exposed to repeated airgun exposures. The objective of this study was to obtain data to develop a scientifically valid method to predict TTS growth, recovery, and affected hearing frequencies as a function of cumulative sound exposure level, taking into account the number of airgun pulses and shot time interval.
