How loud is it in the truck when you are driving?

All depends on the kind of truck you have I would imagine. I have a 2010 670 and I would say its maybe around 50-70 dB but that's totally subjective.

What ?????????

 

if you have to wear ear-plugs while driving, than i would suggest driving a truck with the pipes on back of it.

 

Lupe wearing devices that hinder the ability to hear is illegal in many states,its also unsafe. Here's an example. Your visilbity is limited due to a hill and a ambulance is coming from behind all lit up and sirens blaring. You won't be able to hear it because of the earplugs.

 

It is not nearly as loud as you think it is.

 

Depends alot on the kind of truck you drive and how old it is.

I have found That old frieghtliners are the loudest!

My hearing has suffered severely in the last 5 years. I almost didn't pass my last physical without a hearing aid. Protect your hearing, once it's gone, it never comes back!

 

The noise level in the truck is produced by the exhaust, turbo charger, radiator fan, transmission, tires, etc. If it is difficult to carry on a conversation, the noise level can damage hearing.

Quality road units are very quiet compared to the equipment of thirty years ago. Look for a tractor with a very thick floor mat and a good shift tower boot. Look for an exhaust system that is not mounted to the back of the cab, and does not touch the frame. Look for a flexible fan. Do not mount your deer-whistle near the driver's window. Closing the windows should block most tire and wind noise.
