摘要：

Wild beluga whistle source levels (SLs) are estimated from 52 three-dimensional (3D) localized calls using a 4-hydrophone array. The probability distribution functions of the root-mean-square (rms) SL in the time domain, and the peak, the strongest 3-dB, and 10-dB SLs from the spectrogram, were non-Gaussian. The average rms SL was 143.8 +/- 6.7 dB re 1 mu Pa at 1m. SL spectral metrics were, respectively, 145.8 +/- 8 dB, 143.2 +/- 7.1 dB, and 138.5 +/- 6.9 dB re 1 mu Pa-2.Hz(-1) at 1m.
