The term “free space,” or “free field,” refers to the environment in which the sound source is operating. Free space means that there is nothing to reflect t

Common examples of a duct include the airways used in central heating and cooling systems, and any piping system (including vehicle exhaust systems). Another example of a duct which may not be so obvious is a long hall

As we have discussed in the preceding chapters, the potential for active control to provide a satisfactory result is largely a function of the physical acous
