Which acoustic outcome occurs when a beluga whale's nasal sacs are constrained under high pressure during complex vocalizations?

💡 Explanation

Complex beluga vocalizations depend on modulating air flow through nasal sacs, creating frequency-modulated signals; because pressure changes alter sac vibration properties via controlled Oscillation, precise tones emitted; therefore modulated tone production is enhanced, rather than suppressed directionality under normal circumstances.
