Abstract

Speech detection threshold (SDT) depends on audibility alone, whereas speech recognition threshold (SRT) requires the stimuli to be heard and identified. The aim of the study was to determine the difference between SDT and SRT, and to analyze the correlation between pure tone thresholds and speech thresholds. Difference between SDT and SRT was ≤ 12 dB in majority of cases (p = .018). SDT was strongly correlated with the best pure tone threshold. Pearson correlation coefficient was the highest in “Inverted U” shape (r = .99). There was strong correlation between SRT and PTA (500-2000), PTA (500-4000), and PTA (500-1000), especially in Rising configuration (r = .997, r = .992 r = .989, respectively), as well as, between SRT and frequency of 1000 Hz (r = .989). SRT is in the highest correlation with PTA (500, 1000, 2000 Hz) and with the hearing threshold at frequency of 1000 Hz.
纯音阈值与语音阈值的相关性
语音检测阈值(SDT)仅依赖于可听性,而语音识别阈值(SRT)需要听到和识别刺激。本研究的目的是确定SDT和SRT之间的差异,并分析纯音阈值和语音阈值之间的相关性。大多数病例SDT与SRT的差异≤12 dB (p = 0.018)。SDT与最佳纯音阈值呈正相关。Pearson相关系数以“倒U”型最高(r = 0.99)。SRT与PTA(500-2000)、PTA(500-4000)和PTA(500-1000)之间存在较强的相关性,特别是在上升配置(r = 0.997、r = 0.992和r = 0.989),以及SRT与1000 Hz频率之间(r = 0.989)。SRT与PTA (500,1000,2000hz)和听力阈值(1000hz)的相关性最高。
