摘要
目的：研究正常听力受试者在语音水平为65dB SPL （VRB65）和45dB SPL （VRB45）的情况下进行“快速声跳”（Vocale Rapide dans le Bruit， VRB）语音噪声测试时的心理测量函数曲线和信噪比损失值。材料和方法：成年正常听力受试者按照推荐方案（65dB SPL, VRB65）进行听力学评估，包括鼓室测听、纯音测听、无声语音识别阈值测听和噪声语音测听，然后进行第二组较低句子呈现水平的测试（45dB SPL, VRB45）。结果：29名听力正常受试者中，VRB65和VRB45的心理功能曲线和信噪比损失值无显著差异。结论：“Vocale Rapide dans le Bruit”噪声语音测试是评估噪声环境下听觉困难的有效工具。在听力正常的被试中，不同强度的句子呈现没有显著差异。这是在各种信号呈现水平下使用该方法的必要前提，从而能够评估高阈值和低阈值听神经纤维的功能状态。反过来，这将改进临床诊断并改善与隐性听力损失相关的听力障碍的管理。
Speech audiometry in noise: Signal noise ratio loss values according speech signal level presentation in normal hearing subjects.
Objective: This study aimed to evaluate the psychometric function curve and signal-to-noise ratio (SNR) loss values during the "Vocale Rapide dans le Bruit" (VRB) speech-in-noise test with speech level presentations at 65dB SPL (VRB65) and 45dB SPL (VRB45) in normal-hearing subjects.
Materials and methods: Adult normal-hearing subjects underwent an audiological evaluation including tympanometry, pure-tone audiometry, speech recognition threshold in silence and speech-in-noise audiometry following the recommended protocol (65dB SPL, VRB65), followed by a second series of tests with a lower sentence presentation level (45dB SPL, VRB45).
Results: Among the 29 normal-hearing subjects, there was no significant variation in the psychometric function curves or SNR loss values for VRB65 or VRB45.
Conclusion: The "Vocale Rapide dans le Bruit" speech-in-noise test is a relevant tool for assessing auditory difficulties in noisy environments. In normal-hearing subjects, presenting sentences at different intensity levels did not show a significant difference. This was an essential prerequisite for its use at various signal presentation levels, which could enable the evaluation of the functional state of high- and low-threshold auditory nerve fibers. This, in turn, would refine clinical diagnosis and improve the management of hearing disorders associated with hidden hearing loss.
期刊介绍：
European Annals of Oto-rhino-laryngology, Head and Neck diseases heir of one of the oldest otorhinolaryngology journals in Europe is the official organ of the French Society of Otorhinolaryngology (SFORL) and the the International Francophone Society of Otorhinolaryngology (SIFORL). Today six annual issues provide original peer reviewed clinical and research articles, epidemiological studies, new methodological clinical approaches and review articles giving most up-to-date insights in all areas of otology, laryngology rhinology, head and neck surgery. The European Annals also publish the SFORL guidelines and recommendations.The journal is a unique two-armed publication: the European Annals (ANORL) is an English language well referenced online journal (e-only) whereas the Annales Françaises d’ORL (AFORL), mail-order paper and online edition in French language are aimed at the French-speaking community. French language teams must submit their articles in French to the AFORL site.
Federating journal in its field, the European Annals has an Editorial board of experts with international reputation that allow to make an important contribution to communication on new research data and clinical practice by publishing high-quality articles.
