Music has been played in two opposite galleries with a certain group of people. For example, in the first gallery, a group of 4 singers were singing, and in the second gallery, 9 singers were singing. The two galleries are separated by a distance of 70 \(m\). Where should a person stand for hearing the same intensity of the singer's voice?
 
(Hint: The ratio of the sound intensity is equal to the square of the ratio of their corresponding distances.)
 
A person should stand  from the first gallery.
 
A person should stand  from the second gallery.
