Anning wooden sound-absorbing board manufacturer

Anning wooden sound-absorbing insulation board manufacturer: the ability to reduce sound transmission material. When building subjected to the action of external sound and vibration field or by the impact, the sound will pass through the envelope in, called "sound transmission." Because of the role of envelope structure, passed in sound energy always has decreased, the size of the effect depends on the acoustic performance envelope structure. Isolated from the outer space sound field sound energy, known as the "airborne sound insulation"; make impact energy radiated acoustic energy has decreased, known as the "solid sound or impact sound isolation." This concept of "isolation" is different, the former refers to the sound of air to reach the recipient, the latter refers to the solid feel of vibration recipient. Take measures to reduce the effects of vibration isolation source or sources of the envelope structure impact (eg floor), reducing the crash itself, the sound level basics of a wooden sound-absorbing panels, groove wooden sound-absorbing panels Definition:?
