Grasshoppers hear with organs located on their abdomen rather than their head.

The longer version

Hearing organs sit on either side of the first abdominal segment, tucked behind the base of the hind legs. Each is a thin membrane backed by air sacs; sound vibrations make it flex while sensory cells register the movement. Their relatives rely on the same arrangement rather than ears on the head.

Having them on the sides means arrival times can be compared, giving a rough sense of direction useful when tracking a caller. The membranes respond best to frequencies their own kind produces, so distant calls stand out against background noise. This placement also leaves the head free for feeding and biting.
