8.5Summary of Recommendations

Now that we have looked at some of the common problems of listening rooms, as well as their remedies, let us summarize our findings and recommendations.

Flutter Echo and Standing Waves

These situations are the result of the room having parallel, reflective surfaces. The potential problems are independent of the audio system, and need to be addressed at the source. This means that at least one surface in an opposing pair of surfaces needs to be made less reflective and/or non-parallel.

•Low Frequency Absorption

If a problem exists with standing waves, it is the low frequencies that will need to be addressed. Remember that the absorption spectrum of different materials and objects is not uniform. That is, some items will absorb only high frequencies, and some objects may only absorb the middle frequencies. At low frequencies,
