What does 70 dB sound like?

Given: Sound intensity level LI = 150 dB.

Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing)

Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level)

Get sound intensity I when entering sound intensity level LI = 150 dB:

I = Io×10^(LI/10) in W/m² = 10^−12×10^(150/10) = 1000 W/m².
