Abstract
On the hypothesis that the turbulent flow is practically not affected in character by pulsation of the flow, the formula for sound pressure level of pulsed jet noise is derived in 90° direction and 1 meter away from the nozzle. The steady jet noise is, then a special case when the pulsating frequency is zero. The results agree well with experiments.
