  Acoustoelectric Effect $AE$ in degenerate Carbon Nanotube ($CNT$) was
theoretically studied for hypersound in the regime $ql >> 1$. The dependence of
acoustoelectric current $j^{ac}$ on the acoustic wave number $\vec{q}$ and
frequency $\omega_q$ at $T = 10K$ and scattering angle ($\theta > 0$) was
evaluated at various harmonics $n =\pm 1, 2, ...$ (where $n$ is an integer). In
the first harmonics ($n = \pm 1$), the non-linear dependence of $j^{ac}$ on
$\omega_q$ and $\vec{q}$ were obtained. For $n = \pm 2$, the numerically
evaluated $j^{ac}$ qualitatively agreed with an experimentally obtained result.
