PROBLEM TO BE SOLVED: To provide an acoustic adjusting device capable of easily adjusting a diffuse reflection performance, and thereby adjusting acoustic characteristics of an installed listening room. SOLUTION: The acoustic adjusting device 100 comprises a horizontal floor part 1, a back part 2 vertically erected from a rear end of the floor part 1, side parts 3, 4 vertically erected from both of the right and left ends of the floor part 1, plate-like fins 5 vertically erected from the floor part at equal intervals parallel to and between the side parts 3, 4 so as to form grooves 10 among them, and groove depth adjusting parts 6 which are arranged vertical to the floor part 1 and parallel to the back part 2 in the grooves 10 formed among the seven plate-like fins 5 and which adjust the depths of the grooves 10. The depth adjusting part 6 comprises a reflecting plate 31 as a movable part specifying a depth of the groove 10, a screw 32 of which the head part 32a is on one side and the thread part 32b is on the other side and the head part 32a is embedded in the reflecting plate 31, and a metallic fixture 33 located behind the the reflecting plate 31 in each groove 10.
