Convert sound power in db to Watts

Convert sound power in db to Watts

(OP)
Hello everyone,
I have a text file which contains the values of sound powers in 'db' for different frequencies. This data comes from a acoustic measurement software. Previously, I had written a script in Matlab to simulate this frequency and sound power data as a .wav audio file, using the values of sound powers(db) as amplitudes. The code looks something like:

CODE --> Matlab

Wavaudio = SoundPower*sin(2*pi* frequency*values) 

But then I realised, I can not use the values of sound power directly into my code as the values are in 'db'. I am looking for a workaround to convert the values of sound power from 'db' to 'Watts' or any other unit which allows me to use it directly into my script. I am including my text file with this query just in case!
Waiting for your input. Thank you in advance!
PS : I have a Campbell diagram and I am trying to represent it in the form of a audio file(.wav*). My aim is to get an audio file which produces sound with amplitudes as per the sound power values, for frequencies as given in my text data.

Regards,
Karthik
