用于改善的声音衰减的对称玻璃件
摘要：
一种制造具有与非对称玻璃件相同的名义重量的对称玻璃件的方法，已确定其提供增强的玻璃件强度、玻璃件刚度或石头冲击耐受性，其中所述对称玻璃件相对于所述非对称玻璃件设计的重合频率具有改进的声学衰减。
摘要（英）：

Disclosed is a process for making a symmetrical glazing that has the same nominal weight as an asymmetrical glazing that has been determined to afford enhanced glazing strength, glazing rigidity, or stone impact resistance, wherein the symmetric glazing has improved acoustic attenuation over coincidence frequencies of the asymmetric glazing design.
