HARMONY M3

Harmony M3

Harmony M3 is the first indigenous and most suitable bioacoustic system for airports. The system effectively disperses 53 species of Indian birds and 7 other animal species. Harmony M3 is customised for each airport to suit the birds present, seasonal changes, and day/night. The equipment automatically senses the seasons and day/night and changes the calls accordingly. Randomisation of calls ensures birds do not get used to the system. Based on comparative tests of different bioacoustic equipment in India, conducted by the Ornithology Cell of Indian Air Force, Air HQ, the system is effective on Indian birds/animals at 66.5-82.3%.

The platform includes a control unit, four full-range speakers, a solar panel and a power bank. One system covers about 28-40 acres depending on the ambient sound level at airports. The system is installed at the airport by technical experts of Grus and is covered under a 'one-year replacement guarantee'.
