Speaker Decoupling

Monitor pads can improve the quality of reproduced sound by reducing the interaction between speakers and the surfaces on which they rest. Such products are commonly made out of rubber and represent a small investment that may yield considerable results.

Reflections

When a sound wave meets a solid obstacle of significant size it will have some of its energy deflected and sent back in the direction of origin. Once again the composition and dimensions of the barrier will dictate how much of the energy will be redirected and how much will be transferred. This phenomenon has great importance in the case of musical content, due to resulting alterations of amplitude and timbre as direct and reflected sounds combine.

When numerous ‘versions’ of a signal (echoes) are generated in succession due to the presence of boundaries, sound waves will follow multiple paths and eventually interfere with one another. If the pre-delay gap (the time lapse between direct sound and first reflections) is small, the aforementioned interference will affect the timbre of signals noticeably (due to comb filtering).

Good sounding natural reverberation is the sum of complex reflections that occur under favourable conditions. On the other hand, non-flattering reverb, e.g. flutter echo, is almost always available, although such effect is commonly detrimental to musical recordings and, if possible, best avoided.
