edit Other Pros and Cons. Acoustic guitars do not require any additional equipment, such as amplifiers or power. An electric guitar may lose some sound quality, due to the electric transfers it involves. However, others argue that it has better sound because it can enhance, amplify and modify the sound.
Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airborne sound waves by increasing air resistance, thus reducing the amplitude of the waves. The energy is dissipated as heat. Acoustic Foam can be made in several different colors, sizes and thickness. Acoustic foam comes in a variety of sizes and can be attached to walls, ceilings, doors, and other features of a room to control noise levels, vibration, and echoes.
