audioAttenuation property

The sound attenuation coefficient when users within the sound insulation area communicate with external users. The value range is 0,1. The values are as follows: 0: Broadcast mode, where the volume and timbre are not attenuated with distance, and the volume and timbre heard by local users do not change regardless of distance. (0,0.5): Weak attenuation mode, that is, the volume and timbre are only weakly attenuated during the propagation process, and the sound can travel farther than the real environment. 0.5: (Default) simulates the attenuation of the volume in the real environment; the effect is equivalent to not setting the audioAttenuation parameter. (0.5,1]: Strong attenuation mode (default value is 1), that is, the volume and timbre attenuate rapidly during propagation.
