Is there a way to simulate speaker output from Thiele-Small parameters?

I need to create a simulation of an ideal speaker output. My professor advised me to use Thiele-Small parameters to do it. However, I have only been able to simulate impedance simulation of the speaker. Do you know a way to simulate actual sound pressure output?

Do you understand all the Thiele-Small parameters, such as discussed here?
From the reference efficiency, ηo, you can generate the output acoustic power for a given input power.
From that you can determine the sound pressure versus distance from the speaker.

That only gives me the level of output. I need the exact output signal or the diaphragm offset in given time and frequency.

Why?
You initially said you just needed the output sound pressure.
That can be derived from the sound output level.

Hello

I posted a spice model of loudspeaker a few months ago. The model is configured using thiele-small parameters taken from a speaker datasheet.

search this site for “LTspice Loudspeaker.”
