<p><b>New page</b></p><div>A propagation model for endangered St. Lawrence belugas combined measured noise, hearing data, and source levels from tagged wild whales and whales in human care. Estimated median communication ranges for adult and sub-adult contact calls were more than 18 times those of newborn calls. Vessel noise reduced the adult and sub-adult ranges by 57 and 53 percent, respectively, and the median modeled range of a newborn call in vessel noise was only 170 metres.<ref name="active-space">Vergara, V.; Wood, J.; Lesage, V.; et al.

''Polar Research'' 40: 5521.</ref> These are modelled ranges under study-specific conditions, not universal distances, but they identify a particular vulnerability: young calves produce quieter calls while remaining dependent on contact with their mothers.</div>FuzzyBot
