Types of stimuli
Acoustic
Tymbal organs: buckle inwards causing pressure changes in the abdominal cavity, from which sound is radiated

Stridulation: rubbing rough part of body against another such as wings or legs
Vocal cords or larynx:
long, smoothly rounded bands of muscle tissue that may
be lengthened or shortened, tensed or relaxed, and
opened or closed. Opening and closing of the vocal
folds periodically interrupts the air stream to produce a
tone within the cranial cavities.
