This is 85db when measured next to Robop in our lab. This is not loud when heard outside at the normal distance. It is important to note that the Robop 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. The volume is adjustable using an external button and if necessary can be re-programmed to give any desired sound level.
