sound reflection
7.Main fault models are leaking oil, no absorber function and abnormal sound, and abnormal sound is 50 to 60 percents in the reflection of consumers.
8.Application of Reflection Glass Screen(Windows) for Energy- Saving, Avoiding Dew Drops and Sound Insulation
9.Now, when sound bites are getting shorter, when instant messages crowd out essays, and when individual lives grow more frenzied, college graduates capable of deep reflection are what our world needs.
10.Starting from the fundamental wave equation for acoustics of moving media, a systematic study concerning the reflection and refraction of plane sound waves on the interface between two moving homogeneous media has been made under the assumption that the Mach numbers M of moving media are low, such that M2<<1. The representations for reflection and refraction coefficients as well as the equation decribing the total reflection zone are obtained.
