RE: A Designer Of Controlled Directivity Speakers Speaks Out!

> While not exactly music appreciation, it is known that all things being equal, your ability to understand spoken words is related to the direct to reverberant / reflected level.
Here, reflections and reverberation are NEVER an advantage, they are “noise” that competes for your processing power with the original signal. <

Actually, there is evidence that early reflections improve speech intelligibity:

Bradley et al., “On the importance of early reflections for speech in rooms”, J. of Acoust. Soc. of America 2003, vol.113, no.6, p.3233
Toole, “Loudspeakers and rooms for sound reproduction – a scientific review”, J. of the Audio Engineering Society 2006, p.451 (cited papers)

There is further evidence that for speech early reflections at levels above natural levels are preferred:

Ando et al., “ Subjective preference of sound with a single early reflection ”, Acustica 1977, vol. 37, S.111

There is also evidence that louder reflections are more acceptable with music than with speech:

Munecy et al., "The acceptability of speech and music with a single artificial echo", Acustica 1953, vol. 3, p.169
