Abstract
In the article number 2200357 Tomonaga Ueno, and co-workers report an ultralight single-walled carbon nanotube (SWCNT) aerogel for low-frequency sound absorption, with a hierarchical porous structure and a high-modulus framework. The Biot–Johnson–Champoux–Allard model indicates the significant effect of the high elastic modulus of the SWCNT aerogel on the low-frequency sound absorption.
