In our previous papers, we introduced the notion of a generalized solution to the initial-boundary value problem for the wave equation with a boundary function $\mu(t)$ such that the integral $\int_0^T(T-t)|\mu(t)|^p\,dt$ exists. Here we prove that this solution is a unique solution to the problem in $L_p$ that satisfies the corresponding integral identity.
