The acoustic phonon radiation patterns and acoustic phonon spectra due to electron acousticphonon interaction in double barrier quantum well have been investigated by solving both thekinetic equations for electrons and phonons. The acoustic phonon radiation patterns havestrongly pronounced maximum in the directions close to the perpendicular to the quantumwell direction. The radiation pattern anisotropy is explained in terms of possible electron transitions,nonequilibrium electron distribution function, and the Hamiltonian of electron-phononinteractions
