Time Dependence of Loudspeaker Power Output in Small Rooms
Some new calculations are described which are based on the method of image sources for determining the power output of a sound source operating within the boundaries of a listening room. Although it is well known that the power output of the source is influenced by the near boundaries, the dependence of power output on the nature of the room resonances has been largely overlooked. The analysis presented shows that the near boundary effects are defined by the early part of a general solution evaluated as a function of time after the signal is applied. The solution for time increasing toward steady state shows the progressive influence of the room resonances as they build up.
