December’s issue of Physics Today has a special theme, celebrating the International Year of Sound. The cover features art from Ray Walker’s Hackney Peace Mural in London; topical articles range from acoustic reproduction in historical and cultural preservation, to acoustics in climate change research.

 Sponsored by the International Commission on Acoustics, the International Year of Sound is an education and outreach project to promote understanding of the science of sound and of acoustic best practices.
