Ahmad, Adeel; Siddiqui, M. A. (1988). Physical processes and mechanism of sound production in Field Cricket Gryllus bimaculatus De Geer. Entomon, 13(2): 109-120.
The paper describes the acoustic apparatus of field cricket Gryllus bimaculatus. A model is proposed for the mechanism of sound production. Physical and acoustic apparatus are reported. Mutilation experiments on the elytra of the insect were performed to study the relative contribution of the components of the acoustic apparatus. Different physical processes involved in the sound production such as signal generation, amplification, frequency modukation (FM) and amplitude modulation (AM) are discussed. The quality of the sound analysed by the sonagraphic technique. It consists of fundamnetal (5kHz) and two overtones (10,5 & 16kHz), the former being prominent.
