Yang and Zhang [34] used a damping ratio of 20% for a moving vehicle to compute the contact-point response. 63%) 30mm Porous Absorbent, 15000 Pa. The depth of the enclosed airspace in the box behind the port and the width and depth of the port control the resonant frequency of the bass trap. For a porous absorber it assumes a rigid backing and that backing (ie the wall) is assumed to be air tight. 1/2 of the spring and shock absorber weights. Most importantly, these results should match those in the papers written by the people who developed the models. α = I a / I i (1). Contact. TheAfter plugging those numbers into a porous absorber calculator, I suspect the wool would perform better at greater thicknesses, e. 2 0. Low densities seem good for broadband traps if thick enough.
