They make some interesting noises though include belching, groaning, and popping. Right Whale Slow Zones is a program that notifies vessel operators of areas where maintaining speeds of 10 knots or less can help protect right whales from vessel collisions. Moans, groans, belches, and pulses have most of their acoustic energy below 500 Hz. Description Minke whale in Monterey Bay.
