1.	_______________ defect is due to the lack of reflecting surfaces near the source of sound and excessive absorption of sound in the hall.(a) Exterior noise(b) Loudness(c) Interior noise(d) EchoesI have been asked this question in a national level competition.This key question is from Acoustics topic in section Acoustics and Ventilation of Construction & Building Materials
Answer» 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.
