The intensity level is 65 db at a distance 5.00 m from a barking dog. What would be a reasonable estimate for the intensity level if two identical dogs very close to each other were barking? You can ignore any interference effects.

68 db

Explanation:

Since now instead of one two dogs are barking simultaneously close to each other, therefore we take n = 2.

Ignoring interference effects, the barking of two dogs result in a higher level of intensity which is given by,

β (db) = 10*㏒ (2)

=3 db

So, a reasonable estimate for the raised Intensity Level is: 65db+3db = 68db
