Belfast Zoological Gardens called upon Polar Audio and Saville Audio Visual to provide a weatherproof audio system for its giraffe enclosure. Saville’s Belfast office was engaged to produce a solution that would be used to play bird song to encourage visiting swifts to nest in the nest boxes fitted to the walls of the giraffe enclosure. The Saville team employed an Australian Monitor CS420 IP66 rated, weatherproof column speaker. In addition, an In/Out Dinaplayer, which features a solid state memory, has been designed to automatically play warning messages, voice alerts and different types of audio files. This creates background music to encourage the birds to nest. The Dinaplayer incorporates a 20W mono power amplifier, stereo MP3 player and standard DIN clamp housing, allowing it to be used with different automation systems including touchscreens and industrial computers. According to the zoo, two giraffes have been born in the enclosure since the installation.
