The Effect of acoustic pressure on the radiation of a moving single bubble sonoluminescence (m-SBSL) has been numerically investigated. It is assumed that the bubble interior evolution follows the quasi adiabatic model which is adiabatic in the collapse time and isothermal in remained cycle. To consider the effect of acoustic pressure on a bubble radiation, an argon bubble in water is investigated. It is shown that with increasing the acoustic pressure the bubble's temperature, pressure and radiation increases. The four-order Range-Kutta algorithm is used to simulate the bubble dynamics. The results are in good agreement with the experimental reports on m-SBSL.
