One of the major problems in the study of high frequency phonons in solids has been the calculation of the frequency spectrum of the phonons emitted by a heat pulse generator under specified conditions. This paper compares the calculations using two models; the Little model and the Perrin-Budd model. Satu daripada masalah utama dalam kajian fonon frekuensi tinggi dalam pepejal adalah penghitungan frekuensi spektrum bagi fonon yang dipancarkan oleh penjana denyut haba pada keadaan tertentu. Kertas ini membandingkan penghitungan dengan menggunakan dua model; model Little dan model Perrin-Budd.
