Enterprise crew members applauding a speech by Jonathan Archer.

Among many species, applause was a sign of respect and approval. The act of applause was also known as "clapping".

Bajorans and Wadi applauded by clapping the back of one hand into the palm of the other. Cardassian applause was generated by tapping a table or armrest with a clenched fist. (DS9: "Move Along Home", "In the Cards", "Tribunal", "Sons and Daughters")

Ligonians tapped together two carved ivory-like sticks to signal applause or approval. (TNG: "Code of Honor")

Applause Machine

Applause machine used by Empire Television Network on 892-IV

For Humans, applause was performed by clapping both palms together. This method was also used by non-Human Starfleet officers, and others within the Federation. In 2376, it was copied by the Qomar, who used it in appreciation of musical performances. This type of applause was also in use on Kelis' species in the Delta Quadrant. (VOY: "Virtuoso", "Muse")

On the planet 892-IV, the Empire Television Network used an applause machine for the studio audience in their televised roman arena games. (TOS: "Bread and Circuses")

Another unique way of clapping was used by one member of an unnamed species, which clapped with his arms complete stretched. However, a second member of the species used the Human method, so it is unclear if this was normal for the species.
