Feb 24	comment	Sound Wave Propagation: Why HF are more specular while LF are more omni I guess we will always have at least a size of the source (with corresponding angles). To show that the source is important, one can take HF case, increase the full system (including wavelengths), and obtain exactly the same angles, but the bigger scales. There will be no difference in 'sphericality'. If HF case is less spherical, than LF, go upstream to the source to discover different $\lambda/L$ ratio; and we will always have an implicit scale we compare with. Even HF/LF means small/big $\lambda$, but small with respect to what? With respect to the (unstated) $L$.
