Evaluation of the Speech Intelligibility of the Ear of Dionysius in Syracuse
The Ear of Dionysius cavern has frequently been explored for its unique acoustic properties. According to legend, it amplifies whispers and soft sounds so that they can be heard through a narrow tunnel 35 m above the ground. The legend refers to Dionysius, who ruled Syracuse between 432 and 376 BC and was supposedly able to hear the whispered secrets of prisoners chained in the cave. Acoustic measurements, simulations, and intelligibility listening tests were conducted to investigate the validity of this legend. The results were analyzed and compared to evaluate the definition (D50) and speech transmission index at different locations in the cave. The results show that speech intelligibility in the Ear of Dionysius cavern is rated “fair” overall according to the ISO 9921 criteria, with better values in the central zone of the space. This fair rating suggests that the legend of the tyrant Dionysius eavesdropping on prisoners’ conversations may not be based in reality.
期刊介绍：
Acoustics Australia, the journal of the Australian Acoustical Society, has been publishing high quality research and technical papers in all areas of acoustics since commencement in 1972. The target audience for the journal includes both researchers and practitioners. It aims to publish papers and technical notes that are relevant to current acoustics and of interest to members of the Society. These include but are not limited to: Architectural and Building Acoustics, Environmental Noise, Underwater Acoustics, Engineering Noise and Vibration Control, Occupational Noise Management, Hearing, Musical Acoustics.
