In rigid homogeneous walls, the transmission loss of a one-brick wall

1.	In rigid homogeneous walls, the transmission loss of a one-brick wall is _________(a) 10 dB(b) 20 dB(c) 50 dB(d) 70 dBI had been asked this question by my school principal while I was bunking the class.Question is from Acoustics in portion Acoustics and Ventilation of Construction & Building Materials
Answer» Right option is (c) 50 dB Best explanation: In rigid homogeneous WALLS, the transmission loss of a one-brick wall is 50 dB. The transmission loss of a one and a half brick thick wall is 53 dB and that of a half brick thick wall having 13 mm thick plaster on both SIDES is 45 dB.
