Canada's tanks

Frankly we shouldn't touch Ajax with a 300ft pole until the vibration and sound issue is solved. Id rather not condemn a generation or two of troops to intentional hearing loss due to poor design.

Been solved for a while now hasn’t it?

Yes, but no, according to the story Kirkhill posted above.

Might be at certain revs/speed that excessive vibrations/noise appears. Generally not great for the vehicle or crew. Harmonic dampers, track guides, changes in the drivetrain mounts might be needed.

It doesn't sound too excessive now based on the numbers reported. The vehicle has a reputation now and regardless of what the reality is will always become the focus of any medical claim by a soldier who has worked with them.

Military vehicles are noisy and vibrate. Tracked vehicles travelling at speed especially. It's inevitable. It can be controlled to a certain point but can never be eliminated.

We had ear defenders for all our gunners which were worn around the gun position when firing but rarely worn in the vehicles when traveling. Those needing to be on the radio or intercoms couldn't wear them because of the radio headsets which were inadequate. The others just didn't.

Some tracked vehicles are deceivingly quiet.
The ones with full rubber tracks especially so.
I saw a prototype hybrid system that was for all intents and purposes silent when on electric drive

These days with modern integrated headset earpro/comms and helmets, it’s hard to justify not wearing them.
