“…Other insect groups (cicadas, noctuid and arctiid moths) produce sounds using tymbal organs, which rely on structural deformation followed by rapid energy release (Bennett-Clark 1998, Neil and Holderied 2021). The most conspicuous among these are the calls of cicadas, that show considerable overlap in structure and frequency space with katydids (Fig.…”

Monitoring the species-specific sounds produced by insects could provide us with a rapid, reliable, non-invasive measure of tropical ecosystem health and biodiversity. Although acoustic biodiversity monitoring has made rapid progress over the past decade, the focus has been mostly on vertebrates, even though insects far outnumber them, and tropical soundscapes are dominated by insect sounds. Here we provide an overview of song features for the major sound-producing insect groups, identify technological milestones and describe impediments for analyzing tropical soundscapes and insect communities. We review some promising best-practices using singing insects for non-invasive acoustic profiling and tracking of diversity in rainforest ecosystems under threat. We suggest a roadmap for joint research efforts to accelerate acoustic assessments of singing insects based on re-using the wealth of existing data from Passive Acoustic Monitoring (PAM) in combination with curated multimedia repositories and citizen science.

“…In nature, small hearing animals are equipped with remarkable sound production and reception capabilities, facilitating their communication, mating, and foraging capabilities (Montauban et al, 2021;Neil and Holderied, 2021;Nojiri et al, 2021). For example, a bat produces echolocation by emitting high frequency sound pulses through their mouth or nose and listening to the echoes.…”

This article reports an acoustic Luneburg lens (ALL) design with graded refractive index for passive directivity detection of acoustic sources. The refractive index profile of the lens is realized based on square pillars with graded variation of their dimensions. Numerical and experimental studies are conducted to investigate the performance of directivity detection. The results demonstrate that the lens designed and developed in this study is capable of precisely detecting the directivity of one acoustic source. Furthermore, the directivities of two acoustic sources can also be detected with a resolution of 15°. In addition, different methods are investigated, including introducing phase difference by tuning input signals or moving ALL, and increasing the aperture size of ALL, to improve the resolution of dual sources directivity detection.
