Pierce undertook an analysis of the effects of amplifier damping factor on the decay time and frequency-dependent response variations of a closed-box, acoustic suspension loudspeaker system. The results indicated that any damping factor over 10 is going to result in inaudible differences between that and a damping factor equal to infinity. However, it was also determined that the frequency-dependent variation in the response of the loudspeaker due to the output res…

Webdamping occurs when the coefficient of x˙ is 2 n. The damping ratio α is the ratio of b/m to the critical damping constant: α = (b/m)/(2 n). The ODE then has the form (1) x¨+2α nx˙ + n2x = 0 Note that if x has dimensions of cm and t of sec, then n had di mensions sec−1, and the damping ratio α is “dimensionless,” a number
