The aim of this study was to measure how age affects the speech recognition threshold (SRT) of the Oldenburg Sentence Test (OLSA) and the listening effort at the corresponding signal-to-noise ratio (SNR). The study also investigated the effect of the spatial configuration of sound sources and noise signals on SRT and SNR. To achieve this goal, the study used olnoise and icra5 noise presented from one or more spatial locations from the front and back. Ninety-nine participants with age-related hearing loss in the 18-80 years age range, specifically in the 18-30, 31-40, 41-50, 51-60, 61-70, and 71-80 age groups, participated in this study. Speech recognition and listening effort in noise were measured and compared between the different age groups, different spatial sound configurations and noise signals. Speech recognition in noise decreased with age and became significant from the age group of 50-51. The decrease in SRT with age was greater for icra5 noise than for olnoise. For all age groups, SRT and SNR were better for icra5 noise than for olnoise. The measured age-related reference data for SRT and SNR can be used in further studies in listeners with age-related hearing loss and hearing aid or implant users.
本研究的目的是测量年龄如何影响奥尔登堡句子测试（OLSA）的言语识别阈值（SRT）以及在相应信噪比（SNR）下的听力努力程度。该研究还调查了声源和噪声信号的空间配置对SRT和SNR的影响。为实现这一目标，该研究使用了从正面和背面一个或多个空间位置呈现的olnoise和icra5噪声。99名年龄在18至80岁之间、患有与年龄相关听力损失的参与者，具体分为18 - 30岁、31 - 40岁、41 - 50岁、51 - 60岁、61 - 70岁和71 - 80岁年龄组，参与了本研究。对不同年龄组、不同空间声音配置和噪声信号之间的噪声中的言语识别和听力努力程度进行了测量和比较。噪声中的言语识别随着年龄增长而下降，从50 - 51岁年龄组开始变得显著。对于icra5噪声，SRT随年龄的下降幅度大于olnoise。对于所有年龄组，icra5噪声的SRT和SNR均优于olnoise。所测量的与年龄相关的SRT和SNR参考数据可用于进一步研究患有与年龄相关听力损失的听众以及助听器或植入物使用者。
