The article reveals that the secret behind the cicada's chirp has been discovered after years of unknowing when a research engineer and his colleagues used microcomputed tomography to image a cicada's tymbal, a thin membrane located on each side of its abdomen that make the deafening sound. It says that the cicada's left and right tymbals act like two speakers that produce and constructively combine sound waves and may be replicated for sound propagation in the future using a tiny device. |
