Two methods have been applied to determine the influence of the wood waste content in the stabilized earth bricks, on the weakening of the level of noise reception coming from the environmental medium, in an apartment built with composite bricks (earth + wood chips + cement). This influence has also been analyzed on the magnetic field induced by these bricks. The results showed that the level of sound reception through these bricks decreases with increasing wood waste content regardless of the method used (from 110 dB to 68 dB, respectively for 朴_b = 0% and 朴_b = 8%). The kambala wood waste in cement-stabilized clay bricks induces a magnetic field that increases with the wood waste content; the high contents of the wood chips causing an increase in the magnetic permeability of the composite medium. The correlation between the noise level and the magnetic field of the bricks shows that the noise level declines with increasing magnetic induction of the bricks. %K Kambala Tree %K Wood Waste %K Clay Brick %K Sound Velocity %K Magnetic Field %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=97373
