Sound-absorption Based On Ocean Measurements Pdf

PDF The attenuation term in the sonar equation for propagation loss can be taken to include all losses that are proportional to range. Absorption in the medium is usually the dominant mechanism

  • Based on the results obtained, the following conclusions are drawn for using the device for sound absorption measurements of road surfaces. (1) The sample size should be as large as possible to avoid influences of the surroundings outside the slab.
  • The absorption of sound in seawater is considered as the sum of three contributions: those from pure water, magnesium sulfate, and boric acid. Contributions from other reactions are small and are not included. The pure water and magnesium sulfate contributions obtained from analyses of extensive oceanic measurements, including many in the
