SUMMARY
The discussion centers on calculating sound levels in decibels (dB) from intensity values. The correct formula used is dB = 10 log(I/Io), where Io is the reference intensity of 1E-12 W/m². The user calculated the sound level for an intensity of 4.00 µW/m² (4.00 x 10^-6 W/m²) and arrived at 126.02 dB, while the textbook states the sound level is 66 dB. The discrepancy arises from the misunderstanding of the intensity unit conversion.
