Hello all, I want to simulate Ambient Noise in Underwater acoustic communications. Unfortunately, the given PSD N(f) in dB re micro Pa, so I don't know how to simulate noise signal.

Please help me! Thanks!

Hi, I am also trying to make p.s.d of the ambient noise as same with the figure attached but I couldn't. Can you please tell me that could you be able to draw the same p.s.d of ambient noise or not? if you can draw the p.s.d then please tell me the way or share the code. Thanks
