An active non-lethal infrasound system for denying all bird species access to critical areas, particularly in areas around aircraft and other high value systems. The system comprises a plurality of infrasound generators broadcasting continuous infrasonic signals to create a bird-free infrasound active zone within the perimeters of the protected critical area and an infrasound-free dead zones for birds being denied access to the critical areas. Further, an active infrasonic barrier is assembled within an exclusion area surrounding the bird-free infrasound active zone to dampen all low frequency sound waves emanating from the critical area and its perimeters. Wherever the situation allows, a wildlife sanctuary is preferably established further from the exclusion area to attract and protect birds, enforced by broadcasting infrasound signals that simulate natural sounds that attract species typical of the geographic location.

1. An active non-lethal infrasound system for denying birds access to predetermined areas, comprising: a plurality of first infrasound generators positioned in at least one predetermined first area, the plurality of first infrasound generators operable to radiate overlapping infrasonic waves that interfere with each other to form a plurality of constructive interference patterns to thereby create an infrasound active zone in the at least one predetermined first area; anda plurality of second infrasound generators positioned in at least one second area at a perimeter of the infrasound active zone, the plurality of second infrasound generators operable to radiate infrasonic waves that interfere with each other to form a plurality of destructive interference patterns to thereby create one or more infrasound-free dead zones in the at least one second area, which are outside the domain of the at least one predetermined first area and which provide a refuge for birds being repelled from the infrasound active zone. 2. The active non-lethal infrasound system of claim 1, wherein the constructive interference patterns of infrasonic waves mimic a plurality of navigational cues and natural weather conditions that repel birds from the infrasound active zone. 3. The active non-lethal infrasound system of claim 1, wherein the infrasound active zone is positioned within an airspace portion of an airfield. 4. The active non-lethal infrasound system of claim 3, further comprising a barren exclusion zone that is positioned to surround at least part of the infrasound active zone. 5. The active non-lethal infrasound system of claim 4, wherein the barren exclusion zone is deprived of any avian life-sustenance amenities and constitutes a no-fly bird zone and is not connected to the one or more infrasound-free dead zones. 6. The active non-lethal infrasound system of claim 4, wherein the barren exclusion zone extends to surround at least one of the plurality of second infrasound generators. 7. The active non-lethal infrasound system of claim 3, wherein the infrasound active zone is expanded to encompass all areas in an airport including critical areas around aircraft and other high value systems. 8. The active non-lethal infrasound system of claim 1, wherein at least some of the infrasonic waves are radiated in a frequency range of 0.20 to 0.14 Hz. 9. An active non-lethal infrasound system for denying birds' access to predetermined areas, comprising: a plurality of first infrasound generators that each radiate a continuous and intermittent infrasound signal, the plurality of first infrasound generators positioned in at least one predetermined first area, and the continuous and intermittent infrasound signals from the plurality of first infrasound generators interfere with each other to create an infrasound active zone for repelling birds; anda plurality of second infrasound generators that each radiate signals that cancel the continuous and intermittent infrasound signals radiating at a perimeter of the infrasound active zone by interfering with the continuous and intermittent infrasound signals to create an infrasound cancellation barrier for controlling the spread of infrasound signals outside the perimeter of the infrasound active zone, the plurality of second infrasound generators positioned in at least one second area that is outside the at least one predetermined first area. 10. The active non-lethal infrasound system of claim 9, wherein the infrasound active zone is positioned within an airspace portion of an airfield. 11. The active non-lethal infrasound system of claim 10, wherein the plurality of second infrasound generators each radiate infrasonic waves that destructively interfere to create at least two or more infrasound-free dead zones outside the perimeter of the infrasound active zone. 12. The active non-lethal infrasound system of claim 11, wherein the infrasound-free dead zones are outside the domain of the predetermined areas, located at opposite sides of the infrasound active zone and extended to cover large spaces. 13. The active non-lethal infrasound system of claim 12, wherein one of the extended infrasound-free dead zones constitutes a bird sanctuary that is furnished with feed, water, grass, seedlings and bushes to provide a refuge for birds being denied access to the infrasound active zone. 14. The active non-lethal infrasound system of claim 13, further comprises a plurality of third infrasound generators that mimic the mating calls of a plurality of birds species of interest, the plurality of third infrasound generators positioned outside the infrasound active zone and at least one of the plurality of third infrasound generators positioned in a one of the at least two or more infrasound-free dead zones. 15. The active non-lethal infrasound system of claim 10, wherein the infrasound active zone is expanded to encompass all areas in the airport including critical areas around aircraft and other high value systems. 16. An active non-lethal method for denying birds access to predetermined areas, comprising: providing a plurality of first infrasound generators in a first area;radiating infrasonic waves from the plurality of first infrasound generators to overlap to form a plurality of constructive interference patterns in a domain of airstrips and runways;providing a plurality of second infrasound generators in a second area outside a perimeter the first area; andradiating infrasonic waves from the plurality of first infrasound generators to overlap to form a plurality of destructive interference patterns outside the domain of the airstrips and runways;wherein radiating said infrasonic waves to form said plurality of constructive interference patterns creates an infrasound active zone that repels birds, and radiating said infrasonic waves to form said plurality of destructive interference patterns creates one or more infrasound-free dead zones which provide a refuge for birds being repelled from the infrasound active zone. 17. The active non-lethal method for denying birds access to predetermined areas of claim 16, wherein said predetermined areas are within an airspace portion of an airfield. 18. An active non-lethal method for denying birds access to predetermined areas, comprising: providing a plurality of first infrasound generators in a first area;radiating a plurality of continuous and intermittent infrasound signals from the plurality of first infrasound generators to create an infrasound active zone;providing a plurality of second infrasound generators in a second area outside a perimeter of the first area; andradiating a plurality of signals from the second infrasound generators that cancel the plurality of continuous and intermittent infrasound signals radiated at a perimeter of the infrasound active zone;wherein radiating the plurality of signals that cancel the plurality of continuous and intermittent infrasound signals radiated at the perimeter of the infrasound active zone creates an infrasound cancellation barrier for controlling the spread of infrasound signals outside the perimeters of the infrasound active zone. 19. The active non-lethal method for denying birds access to predetermined areas of claim 18, wherein said predetermined areas are within an airspace portion of an airfield. 20. The active non-lethal method for denying birds access to predetermined areas of claim 18, wherein at least one of the plurality of continuous and intermittent infrasound signals is radiated in a frequency range of 0.20 to 0.14 Hz.
