Question edit
How do porous materials absorb sound better? Please reply I need this for a science project!
Porous material has random voids in them, this allows them to diminish the sound intensity as the sound wave enters the material. The trapped sound wave propagates inside the voids again and again till it fades away. — Preceding unsigned comment added by 157.33.201.165 (talk) 02:57, 10 April 2020 (UTC)
- I am not sure that many people will be watching this talk page, you may like to try posting your question at Wikipedia:Reference desk/Science. Also, try to think of some possible explanations using information from the article, perhaps it has something to do with energy dissipation ability.--Commander Keane (talk) 10:19, 19 September 2008 (UTC)
Complete rewrite edit
Completely rewritten article.
Definitely could do with more work though. Such as a section on measuring absorption coefficients and using them in relevant formulae.
Hope the balance between technicality and comprehension for less techy readers is ok. At least they'll know where to look with all the links (:

References edit
The reference on "Acoustics absorption and sound insulation" zoomito takes you to a link that is not in English and does not have acoustics information. We will need to remove that reference or edit it Mkomboti (talk) 06:30, 13 March 2023 (UTC)
