Here we consider a harmonically-excited (point load on the top floor) four-DOF building model using modal uncoupling. From this procedure we are able to see that the response of the building is ...

FEA can be a useful tool for sizing up resonance problems. Mention FEA and the first things that comes to an engineer's mind are stress and deflection. But FEA can do more than that. It can also show ...

What is modal analysis? Evaluating vibration sensor enclosures and their natural frequencies. Determining the most important modes and frequencies with the mode participation factor. A close look at ...

A listening room, defined by its dimensions, can be mapped in terms of a series of pressure peaks and nulls, in all three dimensions. This refers to the creation of standing waves (modes), and the ...
