我们对听力障碍的进展和病因学的了解主要来自对人群的横断面研究或相对罕见的个别病例研究。仔细分层样本的纵向研究，使科学分析这两个方面的老化听觉系统，也提供了急需的发病率数据的基础上，规划全面的听力服务。这篇初步论文使用了两项研究在相对较短的时间内的数据（英国为2-4.5年，丹麦为8年（DK）证实（a）听力障碍的恶化似乎是持续和渐进的，大多数人（2年评估时高达97%），中位数约为5-6 dB/十年，以及（B）对于应用于平均年龄55的样本的中频平均听力水平（范围40-65）听力损害的发生率通过相关患病率数字的内插准确预测，并且对于25+ dBHL的双侧听力损伤，每年约为1.8%。然而，实际的恶化率似乎确实受到年龄的影响，55岁以上的人表现出高达9 dB/10年的高速率，而55岁以下的人则为3 dB/10年。这意味着需要更长时间的研究才能找到年龄与听力障碍恶化速度之间关系的更准确形式。
Our knowledge of the progression and aetiology of hearing impairments is mainly inferred from cross-sectional studies of populations or individual case studies of relatively rare conditions. Longitudinal studies of carefully stratified samples enable scientific analysis of these two aspects of the ageing auditory system and also provide much needed incidence data on the basis of which to plan comprehensive hearing services. This preliminary paper using data from two studies over relatively short periods (between 2-4.5 years in Great Britain (GB) and up to 8 years in Denmark (DK] confirms (a) that deterioration of hearing impairment appears to be continuous and gradual for the majority (up to 97% on a 2-year assessment) with a median of about 5-6 dB/decade, and (b) that for mid-frequency average hearing levels applied to the samples of average age 55 (range 40-65) the incidence of hearing impairment is predicted accurately by interpolation of the relevant prevalence figures, and runs at about 1.8% per annum for 25+ dBHL bilateral hearing impairments. However, the actual rate of deterioration does seem to be influenced by age, those over 55 showing a high rate of up to 9 dB/decade against 3 dB/decade for those under 55. This implies that study over a much longer time is required to find a more exact form for the relationship between age and the rate of deterioration of hearing impairments.
