SUMMARY
The discussion centers on calculating the combined sound intensity level of three machines producing noise at 76 dB, 82 dB, and 85 dB. The formula used is B = 10 log (I/Io), where I represents the total intensity. The correct approach involves converting the decibel levels to intensity using the formula I = 10^(B/10) and summing these intensities before converting back to decibels. The final intensity level can be calculated by plugging the values into a calculator for the exponents.
