Yes In a Coupled Field Transient analysis (Mechanical R2022 R2), one can define the acoustic pressure (normally not used as excitation but still possible).

Add the static pressure (process what you called) and then superimpose the pulse/transient on top - one can define all that in excel (so pressure vs time):

p_static+p_dynamic(time, say sinusoidal) and paste it in the pressure boundary condition (e.g., as shown below – p_static=1E5 Pa, and p_dyn=sinusoidal / 50 Hz and Amp: 50000 Pa).

All the best
