A technique is described to estimate the sound pressure level developed by a broad frequency response transducer at the tympanic membrane. Real-ear probe tube measurements near the tympanic membranes of 10 subjects were used to obtain frequency-dependent correction values for a custom-designed flat-plate coupler. These latter measures can be used for routine calibration of the transducer. Audiometric thresholds from 250 to 16000 Hz were obtained on 14 children (5-18 years). Threshold estimates were found to be comparable to previously reported values. Potential application and limitations of this technique are discussed.
本文描述了一种用于估计宽频响应换能器在鼓膜处产生的声压级的技术。利用对10名受试者鼓膜附近进行的真耳探管测量，来获取定制设计的平板耦合器的频率相关校正值。这些测量结果可用于换能器的常规校准。对14名儿童（5至18岁）进行了250至16000Hz的听力阈值测试。发现阈值估计值与先前报道的值相当。讨论了该技术的潜在应用和局限性。
