The bellows of male American alligators are accompanied by powerful blasts of infrasound. [38] Another form of male display is a loud head-slap. [ 39 ] In 2010, on spring nights alligators were found to gather in large numbers for group courtship, the so-called "alligator dances".
Alligators and caimans are the noisiest while some crocodile species are almost completely silent. In some crocodile species, individuals "roar" at others when they get too close. The American alligator is exceptionally noisy; it emits a series of up to seven throaty bellows, each a couple of seconds long, at ten-second intervals.

American alligators bellow in B flat (specifically "B♭ 1 ", defined as an audio frequency of 58.27 Hz), and bellowing choruses can be induced by tuba players, sonic booms, and large aircraft. [133]
