That's because EM does not require a medium to propagate. Forces (sound), yes, but not EM itself. Sound is nothing but oscillating pressure. Meanwhile they are not measuring the speed of light anymore. 1907 Rosa and Dorsey, EM constants 299710±30 1926 Albert A. Michelson, rotating mirror 299796±4 1950 Essen and Gordon-Smith, cavity resonator 299792.5±3.0 1958 K.D. Froome, radio interferometry 299792.50±0.10 1972 Evenson et al., laser interferometry 299792.4562±0.0011 1983 17th CGPM, definition of the metre 299792.458 (exact) ?? very funny indeed.
