Recording of “sonic attacks” on U.S. diplomats in Cuba spectrally matches the echoing call of a Caribbean cricket

Beginning in late 2016, diplomats posted to the United States embassy in Cuba began to experience unexplained health problems—including ear pain, tinnitus, vertigo, and cognitive difficulties1–4—which reportedly began after they heard1,2 strange noises in their homes or hotel rooms. In response, the U.S. government dramatically reduced1–3 the number of diplomats posted at the U.S. embassy in Havana. U.S. officials initially believed1,2,5 a sonic attack might be responsible for their ailments… 

Chasing Ghosts in Cuba

This chapter provides a broad overview of a mysterious novel clinical entity featuring mild brain damage and an array of cognitive deficits that reportedly afflicted American and Canadian diplomats

On the Feasibility of Acoustic Attacks Using Commodity Smart Devices

The feasibility of cyber-attacks that could make smart consumer devices produce possibly imperceptible sound at both high and low frequencies, at the maximum available volume setting, potentially turning them into acoustic cyber-weapons is investigated.

Quantifying and contextualizing the impact of bioRxiv preprints through automated social media audience segmentation

This study collected 331,696 Twitter posts referencing 1,800 highly tweeted bioRxiv preprints and leveraged topic modeling to infer the characteristics of various communities engaging with each preprint on Twitter, and demonstrates how the audience segmentation method can quantify the level of interest from non-specialist audience sectors such as mental health advocates, dog lovers, video game developers, vegans, bitcoin investors, conspiracy theorists, journalists, religious groups, and political constituencies.

Reports of inner-ear damage deepen diplomat controversy.

In the latest proposal, Michael Hoffer, an otolaryngologist at the University of Miami in Florida, and his colleagues describe a unique neurological and cognitive disorder in two dozen people evacuated from the Havana embassy.

Symptoms include severe hearing loss, headaches, ringing in the ears, nausea, and problems with balance or vertigo, which are suggestive of a connection to the inner ear apparatus within the human head.

Chasing ghosts in Cuba: Is mass psychogenic illness masquerading as an acoustical attack?

There is a consensus among experts on acoustics and human health that something other than a ‘sonic attack’ is responsible for the symptoms in Cuba, and even if they were able to be focused on a specific target, they are incapable of producing the symptom cluster reported in Cuba.

Neurological Manifestations Among US Government Personnel Reporting Directional Audible and Sensory Phenomena in Havana, Cuba

In this preliminary report of a retrospective case series, persistent cognitive, vestibular, and oculomotor dysfunction, as well as sleep impairment and headaches, were observed among US government personnel in Havana, Cuba, associated with reports of directional audible and/or sensory phenomena of unclear origin.

The control of carrier frequency in cricket calls: a refutation of the subalar-tegminal resonance/auditory feedback model.

The subalar-tegminal resonance/auditory feedback hypothesis attempts to explain how crickets control the carrier frequency (f(C), the loudness and the spectral purity of their calls, and re-affirms the 'clockwork cricket' (escapement) hypothesis.

Systematics and Acoustic Behavior of United States and Caribbean Short-Tailed Crickets (Orthoptera: Gryllidae: Anurogryllus)

The male produces short trills during courtship, and after the spermatophore tube has been inserted and the still-coupled pair has turned end-to-end, the male produces a five- to 20-minute song.

Sound radiation and wing mechanics in stridulating field crickets (Orthoptera: Gryllidae)

These findings show that, as they engage in stridulation, cricket wings work as coupled oscillators that together control the mechanical oscillations generating the remarkably pure species-specific song.

Structural biomechanics determine spectral purity of bush-cricket calls

Using phylogenetically controlled structural equation models, parameters of file tooth density and file length are the best-fitting predictors of tonality across 40 bush-cricket species.
