KEY WORDS:

SUMMARY:

Acoustic absorbers are materials with widespread application in acoustic engineering and architecture, and currently, countless options for such materials are available, and many more are being researched. In aiming to propose new solutions with hardly found features, such as resistance to aggressive environments, the present study investigated the acoustic properties of porous ceramics produced via freeze-casting. Such a method allows the obten- tion of highly porous ceramics, besides good control of pore morphology through variation of fabrication process parameters. The ceramic samples were characterised using numerical and experimental methods related to sound propagation and microstructure. Samples with high sound absorption coefficients in the studied frequency range were obtained, and analysis indicates possible control of acoustic characteristics through fabrication parameter variation.
