Perfect, because a laughing hyena only appears to be laughing.
Generally, high pitched calls signify fear or submission, while low pitched calls accompany a high tendency to attack.
The loud “whoop” is a characteristic sound of the African night and is audible for over 5 km (3 miles) or more. It is a rallying cry, which varies in speed and pitch according to the urgency of the situation. Spotted hyenas also whoop to show off as individuals, the rate and style being an indicator of social status. Because of this, spotted hyenas whoop singly rather than in chorus, as wolf packs do to display their collective strength. Although males tend to whoop more than females of similar rank, dominant females will engage in the longest bouts of whooping. Giggles and grunt-laughter tend to be emitted in situations of great excitement, and perhaps indicate a conflicting tendency to flee or stay. The giggles, yells and grunts which accompany mass feeding tend to be directed at competing individuals at a carcass, and has the secondary, disadvantageous effect of attracting lions and other spotted hyenas.
