随机方法(请说明由何人用什么方法产生随机序列): |
统计人员将“声学预适应干预准备”和“标准准备”分别定义为A组和B组。准备两套完全一致的外包装信封,一套内装声学预适应干预准备内容(A),另一套装一般准备内容(B)。研究协调员打开密封信封,获得该受试者的组别分配(以A组为例)。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Statisticians defined the "acoustic pre-adaptation intervention preparation" and "standard preparation" as Group A and Group B, respectively. Two sets of completely identical outer packaging envelopes were prepared, one containing the acoustic pre-adaptation intervention preparation content (A), and the other containing the general preparation content (B). The research coordinator opened the sealed envelope and obtained the group assignment for that subject (taking Group A as an example). |
