Soundscape, combined with physical environment sound (geophony), organism sound (biophony), and human sound (anthrophony), is a hot issue these years. Anthrophony sometimes was recognized as sound pollution that not only causes physical and physiological problems to human, but also affects the community of animals use acoustic signals. By the end of 2012, most researches emphasize on the impact of anthropogenic noise on vertebrate animals, only two of the 83 papers considered insect species. However, insects can detect sound nearly any segment of the body to frequency between 10 Hz to over 100 kHz. Furthermore, insects use sounds below 10 kHz to communicate, it’s no doubt that insects would be suffered from anthropogenic noise. In our research, we investigated the response of male field crickets, Gryllus bimaculatus De Geer (1773), to ambient anthropogenic noise decibel. By using sound recorders and decibel meters, compare acoustic characters of calling sound with ambient anthropogenic noise level. Moreover, we will sort out the big data of crickets’ sound audio files, which were collected from 1987, to establish database.
