YEREVAN, October 19. /ARKA/. The "Silent Pollution" project which utilizes hydrophones, acoustic data analysis, and interactive visualization to study the underwater soundscape of Lake Sevan will be showcased at the Biodiversity Technology and Innovation Expo, held as part of the 17th Conference of the Parties to the UN Convention on Biological Diversity (COP17) in Yerevan.
According to the official exhibition program, the "Zero Phase" project is included in the first stage of the exposition, taking place from October 19–21, 2026.
As stated on the Silent Pollution website, the project employs an Aquarian H2A hydrophone and a MixPre-3 II digital recorder to capture underwater sounds. Recordings are made at a 24-bit resolution with a 48 kHz sampling rate. The research covers various areas of Lake Sevan, including Shorzha, Artanish, and the lake’s central deep-water section; the collected data are then analyzed based on frequency characteristics and shifts in the acoustic environment.
The installation translates these recordings into sound, vibrations, and water movement. Using a four-channel analog console, visitors can mix underwater sounds while observing the formation of waves and patterns on the water's surface.
The project’s website also cites data from a hydroacoustic study of Lake Sevan conducted in 2020 by specialists from the Institute of Applied Problems of Physics at the National Academy of Sciences of Armenia. According to the developers, the study recorded an acoustic response at approximately 7.5 Hz, as well as signals linked to man-made sound sources, such as a boat and a passing train. However, the study does not determine the extent to which this noise impacts aquatic organisms. *Silent Pollution* is developed by Zero Phase, a creative and research duo consisting of Vanane Boryan and Meyer Gal. The project involves building an archive of underwater acoustic recordings from Lake Sevan and developing interactive methods for presenting environmental data.
Also featured in the first phase of the Biodiversity Technology and Innovation Expo are the Smart Weed Alert Tool (SWAT) for monitoring invasive plants, CTLGH–ILRI with technologies for conserving genetic resources, and Conservation X Labs with solutions for utilizing data on the state of natural ecosystems.
The exhibition, which runs from October 19 to 30, is held as part of COP17 and focuses on innovative technologies for biodiversity conservation.
