Alpha Studio Sound Absorption Eggshell Acoustic Foam Panel is a great tool to improve vocal clarity and acoustics of your recording studios and home theatres, which will effectively flutter echoes and reduce excess reflection and reverberation. It is also an effective way to soundproof your rooms from unwanted or intrusive environmental noise. With its high density acoustic foam cell structure comprising 25kg/m3 and exceptional fire retardant properties, our foams are heavier and thicker than other ordinary acoustic foams for unrivalled noise absorption.
