Non-environment rooms suppress all but direct sound for clearer audio detail and imaging

Evidence

One more important acoustic property of a loudspeaker is its directivity pattern. In an anechoic room, we are only interested in the direct radiation to the listener, but in normal spaces with wall reflections and reverberation the listener receives all these delayed signal counterparts as well. In a relatively reverberant room, it is desirable to use a loudspeaker that has some directivity; that is, it radiates more sound along the main axis than in other directions, especially at middle to high frequencies. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 474 (#corroborates, via linked claim)
