The ultrasound velocities in condensed helium and neon gases have been measured up to 3. 0 and 3. 7 GPa at 295 K, respectively. The velocity was measured with high accuracy by a pulse echo method and using lithium niobate single crystal as the ultrasound transducer. Behaviors of condensed state of monoatomic gases have been discussed from compressibilities and heat capacity ratio.
