Answer:
Yes, I would be able to hear the speaker clearly because the supposedly dropping off of sound as the distance gets farther is counteracted by "reverberations" inside the auditorium.
Explanation:
According to the "Inverse Square Law," if the distance from the sound source is doubled, the intensity of the sound will diminish by 6 decibels. This is true if the situation is in a <em>"free field,"</em> which means the sound has no reflection.
However, this is not the case in an "auditorium." An auditorium causes the <u>"reverberation" of sound. </u>This prolongs the resonance of the sound. So, this means that even if the sound drops off by a factor of 100 (20 decibels), due to reverberations, the height of the ceiling, the kind of wall and materials used in making the seats also affect the intensity of the sound waves. This is the reason why auditoriums are used as venues for <em>concerts, presentations and the like</em> where a <u>large group of people serve as the audienc</u>e.
