Transmission of Low-frequency Internal Sound through Pipe Walls
Transmission loss measurements are reported for long steel pipes of circular crosssection, with air inside and out, excited by internal sound. At low frequencies (wavelength greater than the pipe diameter), most of the radiated sound is accounted for by pipe bending waves. In order to approach the much higher transmission loss predicted for pure breathing motion of the pipe, bending waves must ...
متن کاملSound Transmission through Duct Walls
Acoustic &&breakout'' and &&breakin'' through duct walls had, until the late 1970s, been a rather neglected topic of research, particularly in the "eld of heating, ventilating and air-conditioning ducts. Since then, interest has grown and many publications have appeared in which predictive methods have been reported. Research in this area, especially that which has been conducted over the past ...
متن کاملPredictive Maintenance of Hydraulic Lifts through Lubricating Oil Analysis
This article examines the possibility of measuring lift maintenance through analysis of used hydraulic oil. Hydraulic oils have proved to be a reliable indicator for the maintenance performed on elevators. It has also been proved that the end users or the maintenance personnel do not always conform to the instructions of the elevators’ hydraulic machine manufacturer. Furthermore, by examining t...
متن کاملSound Transmission Through Thin Cylindrical Shells
An analysis i presented ofthe impedance presented by a thin cylindrical e astic shell to a pressure or normal stress as a function of the axial wavelength and the angular dependence of the forces. Results of computation are presented graphically. This information is then used to compute a measure of the sound transmitted through the shell immersed inair for various particular cases. The theory ...
متن کاملMeasurement of Free Air in the Oil Close to a Hydraulic Pump
Noise is a well-known challenge in hydraulic systems and hydrostatic pumps are one of the largest noise contributors in a hydraulic system. The existing noise reduction features, such as pressure relief groove and pre-compression filter volume, are more or less dependent on the working condition. It is essential to know the amount of free air when designing a quiet pump; however, it is not evid...
