    $\begingroup$ Welcome (again). You'll find that when you browse the help centre it'll point out the need for showing your own research when asking a question. Since you self-answered (encouraged, though not usually so quickly done!), then showing research in the Q seems redundant - on this occasion. $\endgroup$ May 8, 2022 at 19:03

Sperm whales produce echolocation clicks, known as usual/ regular clicks (Madsen et al., 2002) and buzzes/ creaks (Gordon, 1987), while they are actively foraging underwater. These are distinguished from other types of clicks based on the repetition rate (known as the inter click interval).

Sperm whales also produce slow clicks (Gordon, 1987), surface/ coda creaks (whitehead, 2003), rapid/ fast clicks, and chirrups. These sounds are thought to be used for communication and/ or to scan conspecifics.

Non click sounds include squeals, pips, short trumpets, and trumpets (Pace et al., 2021).
