Within the modified four-sublattice pseudospin model of deformed RbHSO$_{4}$ ferroelectrics, using the Glauber method and in the mean field approximation we calculate the dynamic dielectric permittivity of a mechanically clamped crystal and explore its dependence on uniaxial  pressures in wide temperature and frequency ranges. A satisfactory quantitative agreement with the experimental data is obtained.
