Hand clap alone, and with side wall reflections
Three hand claps 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.
