Book excerpt: The object of this report is to offer an analysis of the sounds observed in the jungles of the Canal Zone between October 1944 and January 1945. This period includes the last of the rainy season and the beginning of the dry season. The report is illustrated with a phonograph record of the general sounds picked up by a microphone set at various times in different types of jungle areas. It is illustrated also by a phonograph record of the constituent parts of the conglomerate sound, picked up by a microphone usually set in a parabolic reflector and carefully aimed at the source of each sound. In each case it was ascertained that the source was close enough and loud enough to be readily identifiable above all other sounds. In each case the source of the sound was definitely traced - the creature making it definitely identified on the spot or collected (in the case of insects and amphibia) to be identified later by a specialist. The jungle sounds are divided into those of inanimate and those of animate origin. In some places and at certain times such inanimate sounds as wind or rain, the running water of streams, thunder, the falling of trees of branches, or even the sound of the falling leaves of palms or certain other jungle trees completely outweigh the volume of sound from animate sources. In other places and at other times the inanimate sounds are insignificant. (Author).
