The problem is to write a function to calculate the total power loss, measured in dB (decibel), under those circumstances given that:

1. rain leads to an atmospheric loss of 1.5 decibel per kilometre (dB/km)
2. wood leads to a further loss of 90 decibel per metre (dB/m)
3. unknown noise and impairments that might be present, the combined loss (obtained by adding the loss from 1 and 2) is multiplied by 1.01222

You can test your approach with typical values of d = 30 km and t = 0.1 m (which should result in a combined loss of 54 dB, which must then be multiplied by your individual number in order to find the total loss).
