Some important questions about wave localization are addressed. Particular attention is paid to acoustic localization in liquid media containing many air-filled bubbles. It is shown that an amazing collective behavior appears when localization occurs. The study sheds new light to the much discussed subject.5 pages, 4 figures (one in color); Freely available online at http://psroc.phys.ntu.edu.tw/cjp/index.phpClassical Physicstext
