We establish the exact-order estimates for the approximation of functions of several variables from the classes \( {S}_{p,\theta}^{\Omega}B \) defined on *ℝ* ^{ d } in the norm of *L* _{∞}(*ℝ* ^{ d }) by entire functions of the exponential type with supports of their Fourier transforms in the sets generated by the level surfaces of a function Ω*.*
