Person 1 is sitting in a car. The music is playing softly at a volume of 70 decibels. There are some surrounding noises (rain ticking on the window + sounds of other cars nearby + sound of his own engine). The windows are closed, and act as resistance to sounds coming from outside. I'm not sure how to factor these in, and formulate the equation.
Person 2 is located 12 meters away from person 1, standing outside. Person 2 wants to shout a message to person 1, located in the car. The volume of a shouting person is known to be about 90 decibels.
Decibels are measured logarithmically.
From which distance does it get difficult for person 1 to hear person 2? Note that there is a difference between hearing noises and clearly understanding words.
The message of person 2 has to travel a distance of 12 meters, and conquer the resistance of closed windows and surrounding sounds. Plus the 70 decibels of the radio of person 1.
Is it safe to assume that person 1 can not clearly hear (understand) person 2 from such a distance?
Especially in rainy weather with surrounding noises and closed windows.
