The attenuation produced, in dB per meter run of duct, depends ‎on α, the sound absorption coefficient of the lining material and the ratio of perimeter to cross ‎sectional area of the duct (P/S).‎. th. year. The Environmental Effects of Noise. 5.1 The Ear . . When a sound wave enters the ear, it sets the eardrum into oscillation, which in turn causes oscillation of the three tiny bones in the middle ear called the ossicles, Fig.5.1. This oscillation is finally transmitted to the fluid-filled inner ear, the motion of the fluid disturbs hair cells within the inner ear, which transmit nerve impulses to the brain with the information that a sound is present.
