(a) Exterior noise

(b) Loudness

(c) Interior noise

Answer 1

Correct option is (b) Loudness

To explain I would say: The remedies to correct loudness defect consist in arranging hard reflecting surfaces near the source of sound and in adjusting the absorption of the hall so as to give an optimum time of reverberation. Also, the location of loudspeakers should be carefully adjusted.
