Results of a national survey on sound field usage and sound field calibration are presented. Respondents to the survey were 418 ASHA certified audiologists, who answered questions on demographic variables, sound field testing conditions, and sound field calibration procedures. Demographic characteristics of the respondents indicate that they were representative of ASHA certified audiologists. Eighty-one percent of the respondents use sound field audiometry as part of their audiologic practice. Electroacoustic calibration of the sound field stimuli is done most often by an equipment technician, and only a small percentage of the respondents knew how the calibration was done. Results show a lack of standardization among sound field test rooms, great diversity in the stimuli used for sound field testing, and inconsistent calibration methods. Results indicate the need for standards and improved preservice and in-service training in sound field calibration techniques.
本文呈现了一项关于声场使用和声场校准的全国性调查结果。参与该调查的是418名美国言语语言听力协会（ASHA）认证的听力学家，他们回答了有关人口统计学变量、声场测试条件和声场校准程序的问题。受访者的人口统计学特征表明，他们代表了ASHA认证的听力学家。81%的受访者将声场测听作为其听力实践的一部分。声场刺激的电声校准大多由设备技术人员完成，只有一小部分受访者知道校准是如何进行的。结果显示，声场测试室之间缺乏标准化，声场测试所用刺激存在很大差异，校准方法也不一致。结果表明，需要制定标准，并改进声场校准技术的岗前培训和在职培训。
