Phonons 2025 will be the 18th edition of a distinguished conference series dedicated to presenting the most prominent results in phonon physics. This 18th International Conference on Phonon Scattering in Condensed Matter will be held in Buenos Aires, Argentina, and continues the last two conferences held in Paris, France, in 2023 and Nanjing, China, in 2018.

Phonons 2025 will feature plenary sessions on the latest developments, parallel oral sessions with invited talks on key topics, poster sessions, and social events to encourage discussions within the phonon physics community.
