Decibel are measured differently in air vs water. To convert a water dB to air dB, you subtract approximately 62 dB. Different reference pressures are used when measuring in air vs. water. So, the 115 dB in water is approximately 53 dB in air. I think that 115 dB number is also for the submarine at "all stop" because Dot Mod reports a higher dB on the tactical map when you're cruising around at a higher speed than 'all stop'. Hope this helps.

Thanks to PineMartenEmily and tychosis for these insights.
