Unbelievable!
Pharmaaluminum foil has good sound absorption performance for sound. The main factors affecting the sound absorption properties of pharmaaluminum foil are thickness, density and airflow resistance. Density is the weight of material per cubic meter. Air flow resistance is the ratio of air pressure to air flow on both sides of the material at unit thickness. Airflow resistance is the most important factor affecting the sound absorption performance of centrifugal glass wool. The flow resistance is too small, the clarification information is dense, it is easy to pass the air vibration, and the sound absorption performance is good; the flow resistance is too large, the clarification data is dense, it is difficult to pass the air vibration, and the sound absorption performance also falls. The best resistance to sound absorption on centrifugal glass wool. In practice, it is difficult to determine the airflow resistance, but the thickness of the thickness can be roughly estimated and controlled.
- pharmaaluminum foil increases remarkably, but the high frequency does not change much (high-frequency absorption is always large).
2, the same thickness, pharmaaluminum foil bulk density, low frequency sound absorption coefficient also increased; but when the pharmaaluminum foil bulk density increased to a certain extent, the data became dense, the flow resistance is greater than the optimal flow resistance, the sound absorption coefficient instead of landing. However, the thickness and thickness can be roughly estimated and controlled.
