AB  - This paper reports on the influence of individual reflections on the timbre of sound reproduced by a single loudspeaker in a small room. A single loudspeaker with a frequency independent directivity characteristics positioned in a normal size listening room with frequency independent absorption coefficients of the room surfaces has been simulated using an electroacoustic setup. The setup models the direct sound, 17 individual reflections and the reverberant field. The Threshold of Detection (TD) was measured for individual reflections using an adaptive two alternative forced choice procedure and 8 subjects for noise and speech. With the same setup and procedure, Just Noticeable Differences (JND) for an increase of the level of a reflection were also measured for all reflections. The results have shown that only the first order floor and ceiling reflections will contribute individually to overall timbre of the sound field and that noise and speech produce similar values of TD and JND, respectively.
