| What are the main aspects of the signal loss mechanism in the acoustic channel? |
* Answer
| There are two main aspects of the signal loss mechanism in the acoustic channel.On the one hand, the absorption of acoustic signals is caused by the viscous absorption of liquids in the high frequency range: on the other hand, molecular absorption caused by dissolved compounds such as boric acid and magnesium carbonate is the main cause of loss when transmitting low-frequency underwater acoustic signals.. |
