请大家共同探讨：房间的频率特性？ [复制链接]

昨天晚上没事，用声压计测试了房间的频率响应，不知道这样做有没有实际意义，望我们大家共同探讨。
频率[值]            分贝[值]
20                    36
30                    40
40                    43
50                    47
60                    52.8
100                  65.8
125                  65.2
250                  63.7
400                  76
800                  75
1000                68.5
1250                74
2500                85.7
3150                80
4000                71
5000                69
6000                87.7
7000                90
8000                71.5
9000                77
10K                  80
11K                  80
12K                  76
13K                  70
14K                  65
15K                  76
16K                  75
17K                  76
18K                  74
19K                  65.5
20K                  58.6
以上数据是把声压计放在皇帝位测试的实际数值。
