The Associated Press has obtained a recording of what some U.S. Embassy workers heard in Havana, part of the series of unnerving incidents later deemed to be deliberate attacks. The recording, released Thursday by the AP, is the first disseminated publicly of the many taken in Cuba of sounds that led investigators initially to suspect a sonic weapon. The recordings from Havana have been sent for analysis to the U.S. Navy, which has advanced capabilities for analyzing acoustic signals, and to the intelligence services, the AP has learned. The Navy and the State Department did not respond to requests for comment on the recording. Not all Americans injured in Cuba heard sounds. Individuals who have heard the noise in Havana confirm the recordings are generally consistent with what they heard. Then there would be silence for a second, or 13 seconds, or four seconds, before the sound abruptly started again. All these peaks correspond to a different frequency," said Kausik Sarkar, an acoustics expert and engineering professor at The George Washington University who reviewed the recording with the AP. The recordings have been played for workers at the U.S. Embassy to teach them what to listen for, said several individuals with knowledge of the situation in Havana. The broad array of symptoms reported, including those not easily explained by sound waves, had led to questions of a possible microwave or radio wave device frying body tissue from afar.
