Estimation of Transient Sound Power Using Probabilistic Model of Random Impact Forces and Application to Noise Reduction
2008
Journal of System Design and Dynamics
This paper describes the estimation method of transient sound radiating from a structure excited by random impact forces and the noise reduction design of a coin storage box of a coin counting machine. To represent the random impulses, the probabilistic model of random impact forces is derived by defining the collision position and time of impulses as probability variables and using the probability density functions of the variables. The probability density functions of the collision position
