Among the loudest animal voices to be heard in South East Asian Rainforests are those produced by cicadas (Insecta: Homoptera: Cicadidae). An unexperienced listener probably does not associate their loud, weird-sounding voices with an insect! This site provides acoustic examples of some cicada songs.
Recordings were made in April 1994 at Poring, Kinabalu National Park, Sabah, Malaysia. Thanks to Sabah Parks for assistance!
Sounds were sampled with Soundblaster, at a sampling frequency of 22kHz, in wav-format. For Unix-Users, some files are converted to au-Format.
