DEVELOPMENT OF THE AUTONOMOUS UNDERWATER NOISE RECORDER

24-osios jaunųjų mokslininkų konferencijos „Mokslas – Lietuvos ateitis“ teminės konferencijos Aplinkos apsaugos inžinerija straipsnių rinkinys, 2020
An underwater noise is the most pervasive type of physical energy that spreads in underwater marine environment. The concerns regarding man-made underwater noise effects on the aquatic animals became prominent within scientific communities. The determination of underwater noise levels became very actual either for environmental monitoring or scientific

Near-field and high-resolution cylindrical noise source location method based on vector sound pressure array

Zhongguo Jianchuan Yanjiu, 2017
The existing underwater noise source near-field location method usually assumes that the measurement plane is flat, which increases the difficulty of applying the underwater noise target test for cylindrical distribution. Simultaneously, the conventional
