Re: reflection of the (ultra)sound waves
><: I'm looking for the information about reflections of (ultra)sound waves from soft (e.g. human body or soft polymers), respectively hard (e.g. wood) materials. In particular:
: 1. Differences in the changes of the wave attenuation and/or velocity upon reflection from hard material compared to the reflection from the soft material.
: 2. Is there a material dependent wavelength intervall where these differences are particularly large?
: 3. Where to find theoretical description of these changes?
: 4. Where to find material constants enabling to evaluate these changes?
: Will appreciate your response
: Best regards
: Anatol Krozer
