In cavity wall construction for soundproofing, the width of the cavity

1.	In cavity wall construction for soundproofing, the width of the cavity should be at least _________(a) 3 cm(b) 5 cm(c) 8 cm(d) 12 cmThe question was asked by my school principal while I was bunking the class.I would like to ask this question from Acoustics topic in division Acoustics and Ventilation of Construction & Building Materials
Answer» RIGHT OPTION is (B) 5 CM For explanation: In cavity wall construction for soundproofing, the WIDTH of the cavity should be at least 5 cm. This type of construction ideal from the point of view of soundproofing. The cavity is either left air-filled or filled with some resilient material.
