Abstract：
OBJECTIVE: Communicating in noisy settings can be difficult due to interference and environmental noise, which can impact intelligibility for those with hearing impairments and those with normal hearing threshold. Speech intelligibility is commonly assessed in audiology through speech audiometry in quiet environments. Nevertheless, this test may not effectively assess hearing challenges in noisy environments, as total silence is rare in daily activities. A recently patented method, known as the SRT50 FAST, has been developed for conducting speech audiometry in noise. This new method enables the acceleration and simplification of free field speech audiometry tests involving competition noise. This study aims to establish normative scores and standardize the SRT50 FAST method as a test for evaluating speech perception in noise in pediatric patients.
METHODS: The study included 30 participants with normal hearing, consisting of 11 females and 19 males, ranging in age from 6 to 11 years. A series of speech audiometry tests were conducted to determine the speech reception threshold 50% (SRT50) in competing conditions. This included testing both the fast mode (SRT50 FAST) currently being studied and the traditional method (SRT50 CLASSIC). The SRT50, or Signal to Noise Ratio (SNR) at which 50% of speech recognition occurred, was investigated for both methods.
RESULTS: The mean SRT50 FAST test score was -2.69 (SD = 3.15). The dataset exhibited a normal distribution with values ranging from 3.60 to -8.60. Since the scores are expressed in SRT, higher scores indicate poorer performance. We have established a threshold of 3.60 as the upper limit of the normal range, therefore, patients with scores above this threshold are considered to have abnormal results.
CONCLUSIONS: This study aimed to establish normative data for the evaluation of free field speech in noise recognition using the SRT50 FAST method in the pediatric population. This method accurately investigates the necessary signal-to-noise ratio for achieving 50% recognition scores with bisyllabic words in a quick manner. The ultimate objective is to employ this test to identify the optimal configuration of hearing rehabilitation devices, particularly for pediatric patients with hearing aids and/or cochlear implants. Additionally, it can be used to assess pediatric patients with unilateral hearing loss.

摘要：
目的：由于干扰和环境噪声，在嘈杂的环境中通信可能很困难，这可能会影响听力障碍和正常听力阈值的人的清晰度。通常在听力学中通过安静环境中的语音测听来评估语音清晰度。然而，此测试可能无法有效评估嘈杂环境中的听力挑战，因为在日常活动中完全沉默是罕见的。最近获得专利的方法，被称为SRT50FAST，已开发用于在噪声中进行语音测听。这种新方法可以加速和简化涉及竞争噪声的自由场语音测听测试。这项研究旨在建立规范评分并标准化SRT50FAST方法，作为评估儿科患者噪声中语音感知的测试。
方法：该研究包括30名听力正常的参与者，由11名女性和19名男性组成，年龄从6岁到11岁不等。进行了一系列语音测听测试，以确定竞争条件下的语音接收阈值50％（SRT50）。这包括测试当前正在研究的快速模式（SRT50FAST）和传统方法（SRT50CLASSIC）。SRT50，或信噪比（SNR），其中50%的语音识别发生，对这两种方法进行了调查。
结果：平均SRT50FAST测试评分为-2.69（SD=3.15）。数据集表现出正态分布，值范围为3.60至-8.60。由于分数以SRT表示，分数越高，表现越差。我们已经建立了3.60的阈值作为正常范围的上限，因此,得分高于该阈值的患者被认为结果异常.
结论：本研究旨在建立规范数据，用于在儿童人群中使用SRT50FAST方法评估噪声识别中的自由场语音。该方法准确地研究了用双音节词快速实现50％识别分数的必要信噪比。最终目标是使用此测试来确定听力康复设备的最佳配置，特别是对于患有助听器和/或人工耳蜗的儿科患者。此外,它可用于评估单侧听力损失的儿科患者。
