However, they don t go about it in exactly the same way as humans. Chimpanzees, as well as other animals, communicate vocally but non-verbally, meaning they make noises that indicate their general mood, but they don t use words to communicate exactly how they feel.For a chimpanzee words are often unnecessary; they can make their intentions clear without them. Vocal communication.e know that laughter is normally associated with happiness and feelings of joy and that crying and whimpering is normally associated with feelings of sadness. This is the same as in chimpanzees! A chimpanzee will whimper or cry when they are feeling distressed and laugh when they feel excitement.
