This is a picture at New Hope Windward where I currently play drums for the worship services. If you look closely to my drumset you will see the clear transparent drum shield. The surrounding acrylic glass shield is vital to the sound of my drums. Soundwaves reflects from a smooth surface the same way that light does. If I were to bang on my drumset without the shield, I would send sound waves in all directions reflecting off the walls of the theater. As the sound waves from my drums bounce off the walls, it causes too much reflections thus resulting in reverberations. The purpose of my drum shield is to simulate playing in a enclosed room. The shield balances out the reverberation and absorption of my sound waves to give me a crisper and more lively sound when I play on stage.
