Xylophone alone, and with side wall reflections
Xylophone recorded live in an anechoic room on the left channel, followed by the same anechoic recording played back with the addition of a 2.7 ms delay (-2 dB SPL for distance) simulating a first order reflection from the left side wall, and a 13 ms delay (-6 dB SPL for distance) simulating a first order reflection from the right wall. This is typical of side wall reflections found in a typical room. The simulated delay approximates a room about 5 meters (16 ft.) wide, with speakers positioned appropriately away from the walls. Notice that the delay causes an audible echo, as well as a shift of the image in space. It is important to absorb or diffuse first order reflections for sound quality integrity.
