Table 1 Calibrated source levels for exposure stimuli

From: An animal-borne active acoustic tag for minimally invasive behavioral response studies on marine mammals

Stimulus Source level
White noise 125.56 (0.94) @ 1 m (dBRMS re 1 µPa)
Common dolphin whistles 130.66 (1.48) @ 1 m (dBRMS re 1 µPa)
Sperm whale clicksa 131.77 (1.89) @ 1 m (dB0-peak re 1 µPa)
Killer whale whistles 121.06 (4.60) @ 1 m (dBRMS re 1 µPa)
Killer whale clicksb Estimated 126 @ 1 m (dB0-peak re 1 µPa)
Sonar 124.27 (0.58) @ 1 m (dBRMS re 1 µPa)
  1. Mean and standard deviation of two calibrated recordings are given. All sources levels are given in dBRMS re 1 µPa @ 1 m over the stimulus duration, except for the sperm whale click tracka, which was measured in dB0-peak re 1 µPa @ 1 m and the killer whale click trackb which was measured by relative comparison to killer whale whistles
