Mr. Nikhil Banda, That was very insightful. Your studies and experience in underwater acoustics speak volumes. I'm sure your answers would certainly help many aspirants in this field. I wish the conference a great success and hope it brings out many solutions to the world problems.
Great job Dr., In addition to using electric engines, I believe including drone operations into regulatory standards (similar to aircraft) would also be a good measure to curb noise or other environmental menace

I worked a ship once that had a Roots blower mounted on the sewage plant tank, that ! was a loud M F-er , i baffled out and dampened with material the inlet housing , but it was small gains as i modded that housing , 4 or 5 times, did manage to make it tolerable. That fan (if you can call it that) had been assaulting peoples ears for decades ! if not for me nothing would have changed, people are amazing adapters ... not always to their benefit ?
Yup talk about plant supervisors just wanting you to adapt, its total BS ! ... The plant where i worked had a exhaust fan that just howled all day long, i knew it needed bearings a rebalance AND a cleaning, boss would have no part of repairing it, so everyday for a week i tightened up the drive belts till they were like guitar strings and then i just waited, Didn't take long and the bearings blew, so the fan got overhauled and it was like night and day change in sound level ! My boss pretended it was no big deal , what a D-bag , that fan was like that for over a year, i have no respect for people who think their co-workers health (hearing & stress) is expensable !
What a fascinating lecture !! It is amazing to think Dr Beranek is 100 years old, what a brilliant man. Hats off to him and hope I can make it to that age as healthy, sharp and knowledgeable as that.
