Yes, it is. It remarkably fades the sound, however it depends on thickness of wall and mix design of Leca concrete.
Thermal conductivity coefficient for Leca Aggregate is about 0.09< λ < 0.101
Due to Leca physical characteristics, it remains unchanged consistently.

Natural clay is 100% of raw material to produce Leca (light expanded clay Aggregate).
Pretrea ted special kind of clay is derived to rotary kiln, and exposed to high temperature, then clay is expanded in a granule shape with honeycomb core and ceramic shell.
Leca is an acronym term for (Light Expanded Clay Aggregate).
