Variation of Frequency of sound underwater

Click For Summary
SUMMARY

The frequency of sound underwater is primarily determined by the sound source rather than environmental factors. However, the speed of sound in water is influenced by temperature and depth, with higher temperatures leading to increased sound speed. Understanding these relationships is crucial for applications in underwater acoustics. Key formulas related to sound speed in water include those that incorporate temperature and pressure variations.

PREREQUISITES
  • Understanding of underwater acoustics principles

Hello,

I am very much interested to how frequency of sound varies in water. Also, how the frequency varies with temperature and depth? What are the different formulas related to this? Secondly, how can we determine the best frequency of operation? I would be very thankful if anyone could answer the above questions or point to materials explaining the above.

With regards

It doesn't. The frequency depends on the source that produces the sound.
Maybe you mean the speed of sound. This indeed depends on temperature of the medium.
