Robop the Ultimate Bird Control System Effective and humane bird repellent system
It ranges from 64-85db when measured next to a Robop bird prevention unit in our lab. This is not loud when heard outside at the normal distance. It is important to note that the Robop bird prevention unit voice is no louder than that of a real peregrine, which is not particularly loud. Do not confuse Robop with acoustic bird scaring devices which can be very loud indeed.
