Perfect for improving vocal clarity and acoustics of your room these foams will effectively flutter echoes and reduce excess reflections and reverberation. Where it features a high density acoustic foam cell structure and is highly fire retardant these acoustic foams are one of the few that are of premium quality. As pyramid and wedge shaped acoustic foams have a thicker body the noise absorption will be higher compared to eggshell shaped acoustic foams. Some sellers claim that black acoustic foams are of better quality in regards to noise absorption. However in fact there is no direct relation between the noise absorption and colour. More importantly it is the density which determines the level of noise absorption. Where these acoustic foams feature a high density of 25kg/m3 you can be assured this is where you will find heavier and thicker acoustic foams.
