困扰全球多地居民数十年的神秘低频嗡鸣声现象可能终于找到了解释。挪威科技大学研究团队对这一现象进行了科学调查，测试了28名报告听到该声音的德国人，以验证两个主要假设：参与者是否具有异常灵敏的低频听觉，以及内耳是否产生可测量的声音1。研究结果表明，大多数情况下该现象可能源于低频耳鸣，即声音来自听觉系统内部而非外部环境1。
研究发现，在28名参与者中，只有2名在某些低频段具有高于平均水平的听力1，而研究未发现任何参与者具有耳声发射现象1。这一神秘现象已在全球引起广泛关注，约占全球人口的2-4%报告听到过这种嗡鸣声1，其中最早的大规模关注始于1970年代中期的英国布里斯托尔1。研究已发表于《PLOS One》2026年第21卷第3期1。
Researchers at Norwegian University of Science and Technology have investigated the worldwide phenomenon of a mysterious low-frequency hum that has been reported across multiple continents for decades, offering new scientific insight into its origin 1. The study examined 28 German participants who reported hearing the sound, testing two primary hypotheses: whether listeners possessed unusually sensitive hearing at low frequencies, and whether the inner ear generated measurable sound 1. The findings indicate that in most cases, the phenomenon likely stems from low-frequency tinnitus—meaning the sound originates from within the auditory system rather than from an external source 1.
The mysterious hum, which affects approximately 2 to 4 percent of the global population according to reports, first drew widespread attention in Bristol, England during the mid-1970s 1. Only 2 of the 28 test participants demonstrated above-average hearing sensitivity at certain low frequencies, and researchers detected no oto-acoustic emissions in any of the subjects 1. The research was published in PLOS One, Volume 21, Issue 3 in 2026 and distinguishes between low-frequency sounds in the range of 20 to 250 hertz and infrasound below 20 hertz 1.
