One residential property is located 60m from a noisy factory and a second residential property is located at 30m away from the factory and in the same direction as the farther property. If the level of noise at the nearest property due to the factory is 50 dBA, what noise level can be expected at the farther property (assuming there will be no shielding from objects and that the only attenuation of the factory noise will be due to the increased distance)? a. 24 dBA b. 30 dBA c. 44 dBA d. 47 dBA e. 50 dBA
