Figure 5

Sound guiding and acoustic Talbot effects at different frequencies. (a–c) The experimentally measured sound guiding effect for the operating frequencies of 2800 Hz, 3300 Hz, and 3600 Hz, respectively. (d–f) The experimentally measured Talbot effect for the operating frequencies of 2800 Hz, 3300 Hz, and 3600 Hz, respectively.
