Why Use Sonic Nets?

Two Billion Birds Are Killed in the USA Every Year

According to US Fish and Wildlife studies about one billion of those deaths occur from birds running into buildings, cell towers, wind turbines and other manmade structures, and globally the number is much higher.

Birds Cause Billions of Dollars of Damage Every Year

Despite all the mortality, birds continue to cause a huge amount of damage to human infrastructure - vineyards, airplanes, bait fish farms, ports - they get into everything. The birds cannot help it, they are just being birds. And being birds they also habituate - or get used to - most deterrent methods, whether it is the venerable scarecrow or sonic cannons.

Sonic Nets: Benign Acoustic Deterrence

Midstream Technology - in collaboration with the College of William and Mary - is continuing the research and commercialization of new acoustic technology to help reduce the stress and mortality to animals and birds by human activity and structures, and reduce the damage caused by animals and birds in agriculture, aquaculture, airports, marinas and more.

Sonic Nets projects unique sounds that are no louder than a bird normally talks that make it hard for the birds to understand each other. Sonic Nets is also designed to use parametric speakers (an array of very small speakers) to "shape" the sound so no one else hears it - except the birds or animals you are targeting. You can even target a specific bird or animal species. These sounds cause the birds to look up - meaning they are less likely to run into something - and because they cannot understand each other, they go somewhere else to "talk."

William & Mary Aviary Trials

In one of the first trials of the Sonic Nets technology, parametric speakers projected low-level unique noises into one side of the aviary, with food placed in the target area for European starlings. The test was successful with the starlings increasing their heads up behavior then leaving the target area. The results will be published in late 2014.

William & Mary produced a video of the new technology, which can viewed on Youtube.
