Abstract
An original theory of special relativity acoustics is developed. For this new theory with a focus on sound waves instead of electromagnetic waves, new coordinate transformations that are different from the Lorentz transformations, which transform a spherical wave front for the observer at rest into another spherical wave front for the observer in uniform relative motion, are deduced. Previously, it has been quantitatively demonstrated that Lorentz transformations do not do what Albert Einstein says they do. In the demonstration that is described in the present study, we conclude that the constancy of the speed of light, using the Lorentz transformations, for one of the two observers, is not satisfied. Also, within this new acoustic theory new expressions for the Doppler Effect are obtained, with differences in regard to the traditional expressions. Finally, new relativistic consequences are found that present differences with respect to those from the theory of Albert Einstein.
