Color: grayFeatures:SOUND ABSORPTION: Sound dampening curtain Large Unfolded Size: 48"x 48", Thickness 15mm. Folded Size: 21"x21". This dampening curtain is a combination of polyester and chemical fiber cotton. The white chemical fiber cotton inside will reduce the incoming noise, reduce the sound echo and reverberation in the room, create a quieter atmosphere, allow you to have a more comfortable environment for work, study and rest, and improve sleep quality.WHITE SYNTHETIC COTTON: The performance of felt in sound absorbtion is as a result of its optimum density and spring. The absorption of sound waves is achieved by the vibration of individual fibres within the felt. The energy is dissipated by frictional heat loss. Due to its method of absorbtion, too dense felt would not allow for sufficient vibrations. These qualities make it excellent for industrial sound proofing. Felt is also used as a damper in musical instruments.WIND & COLD PROTECTION: Thickened and warm, it can resist
