The author's artistic experiment The Hearing Test focuses on detection of high frequency clicking sounds that are emitted by the tips of plants' roots. Scientists have claimed that plants' roots produce high frequency clicks between 20 and 300 kHz by bursting air bubbles. But while the phenomenon has been described, its cause remains unexplained. This lack of knowledge opens up possibilities for multiple interpretations and invites experimental approaches as well as speculation concerning plant intelligence, the role of species-specific hearing and sound as evidence. The article is an extended reflection on the experiment.

听力测试：植物实体的证据

作者的艺术实验 The Hearing Test 重点检测植物根尖发出的高频咔嗒声。科学家声称，植物的根部会通过气泡破裂产生 20 到 300 kHz 的高频咔嗒声。但是，虽然已经描述了这种现象，但其原因仍然无法解释。这种知识的缺乏为多种解释开辟了可能性，并引发了关于植物智能、物种特异性听觉和声音作为证据的作用的实验方法和推测。文章是对实验的延伸反思。
