Orbital-moments’ segregation $\textbf{L}_{\textbf{r}}$ makes ‘orbital glass’ (OG). Covalent interactions $\Gamma _{k}$ of Galois-group elements (GG-$j$) ($j$ = $x$, $y$, $z$ = 1, 2, 3) express by elementary excitations $E_{q}$ in $j$-domain (GG-$j$). Connection $E_{q}$ with phonons renormalizes sound frequency $\omega _{k}$ (functional $\Delta\omega _{k}$ ($E_{q}$) is added). Wall between domains ($j$ = $y$, $z$) with thickness $\delta_{W}=(\Gamma /K)^{1/2}$ and energy $E_W=(\Gamma K)^{1/2}$ is determined by constant $K$ of $j$-domain anisotropy. Wall mass ($m_{W}\propto E_{W}$) and its stabilization $P_{W}$ give oscillation spectrum $E_{W}(W_{ij})$. It may be used as non-ferromagnetic sonars.
