The materials were selected on the basis of their usage in human hearing protection devices that gave an average advertised reduction of 20 Db. So that, or better, is the Db reduction number that was designed for. The second consideration was the high frequency noise that is beyond the range of human hearing. Assuming the noise reduction properties of Mutt Muffs is in the 15-25 Db range at human frequencies, we can assume an even better number in the high frequency range for the simple reason that the higher frequency, shorter wave length, is easier to diminish then the longer wave length of human hearing range. The reason: the wave has to travel further, in relation to its length, to pass through a given thickness of material. Mutt Muffs are designed not to block out all sound, but to be a passive, noise reducing device that will make a ride in the airplane a comfo
