How far can a "banger" be effectively used to repel birds?

The effective range of a "banger," which is a type of noise-making device used to scare away birds, is typically between 50 to 100 feet. This range allows the loud sound produced by the banger to reach a distance where it can effectively disturb and deter birds from nesting or feeding in a particular area. By creating a sudden, startling noise, bangers exploit the birds' natural instinct to flee from perceived threats. This effectiveness is crucial in wildlife control efforts, particularly in agricultural settings or places where birds may cause damage.

While other options suggest shorter or longer distances, the sound attenuation and the birds' ability to rationalize threats factor into the effectiveness of the banger. Sounds do diminish with distance, hence why achieving the desired repellent effect is most reliable within the identified range of 50 to 100 feet.
