Измерены частоты акустического и электромагнитного резонансов в квазисферическом акустическом резонаторе при температуре тройной точки воды. Резонатор заполнен гелием4He. На основе анализа экспериментальных данных получено значение постоянной Больцмана kB =1,38065108·10-23 Дж×К-1 с неопределённостью 2,34 млн-1.

The frequencies of acoustic and microwave resonanse of a quasi-spherical acoustic resonator filled with helium have been measured at the temperature of triple point of water. Resonator maintained near the temperature of the triple point of water and filled with helium. The value of the Boltzmann constant kB =1,3806508·10-23 J·K-1 with standart uncertainty 2,34 ppm has been obtained.
