Gearbox Noise and Vibration Prediction and Control

This paper will review practical techniques and procedures employed to quiet gearboxes and transmission units. The author prefers solving the gear noise problem at the very source to introduce an enclosure as a means to reduce radiated noise, which seems to be easy but its effect on the sound pressure level is small. The gearbox noise problem solution is focused on the improvement of gear desig...

Rotorcraft Vibration and Noise Prediction Using a Unified Aeroelastic Analysis

A study of the combined helicopter noise and vibration problem was conducted. A refined aerodynamic model capable of calculating the unsteady surface pressure distribution on rotor blade/flap combinations is developed and coupled with an aeroelastic analysis simulation code. An acoustic prediction tool based on WOPWOP is combined with the aeroelastic analysis based on a flexible blade with coup...

Prediction of Shot Noise

Prediction of future values of a shot noise process observed on a discrete lattice of points is considered. The shot magnitudes are assumed to be independent and identically distributed and arrive via a Poisson process; the eeect of each shot dissipates and/or accumulates according to a known shot function. Conditional mean and linear point predictors of future process values are developed. Dis...

Prediction of Crowd Noise

The prediction of crowd noise is a problem faced by acoustic consultants. Although consultants are frequently required to predict noise emissions from activities involving crowds of people, there are no prediction methodologies available. This paper discusses the factors influencing crowd noise with the aim of encouraging discussion about how the problem of predicting crowd noise can be overcom...
