Resumo

Frequencies of acoustic and electromagnetic resonances were measured in a quasispherical acoustic resonator at the temperature of the triple point of water. The resonator was filled with helium ⁴He. Based on the analysis of experimental data, a value for the Boltzmann constant of k_B = 1.380651·10^–23 J·K^–1 with uncertainty of 2.4 ppm was obtained.
