Abstract
An acoustical cap that covers a microphone and allows a user to adjust the frequency response of the sound that the microphone receives. The acoustical cap has at least two different inlets that connect to respective cavities. These inlets and their associated cavities form resonators that have different frequency responses. Because the microphone cap has multiple resonators, a user is able to quickly and easily adjust the frequency response of the sound that the microphone receives by adjusting the orientation of the acoustical cap instead of having to carry multiple acoustical caps.
