Since my ad hoc noise control system described in another post below didn’t work, my ears and brain cried for relief.
The temporary solution was two pair of JD noise cancelling head phones. These worked better than I expected. A heated cab is a requirement for wearing them in the winter. There is also a difference in performance between the two pair that we purchased. The microphone/circuits in one picks up the thump of the tracks hitting an obstruction and magnifies the sound. No problem in snow but annoying in rougher terrain. (Now that we’ve switched back to tires, that particular noise doesn’t exist.) Headphones are a pain if you are in and out but head phones appear to be an ideal solution when doing a single job like spraying fence rows or ditches.
Ordered some sound insulation foam from Parts Express International on Amazon.
Two 18” x 24” panels of Sonic Barrier 1-1/4 3-Layer Damping Material w/PSA were installed on the steel panel underneath the rear window. The fit is almost perfect. The PSA adhesive solves the attachment problem but makes fitting difficult. I punched out recesses for the bolt/nut heads. The biggest problem is in fitting around the seat belt retractors. Easiest to install the foam and then cut the reliefs.
With the sonic barrier in place, you have a place for two waffle panels to butt into. (Acoustic Foam 2-1/2" x 24" x 18" UL 94). These take a lot of cutting and fitting to fit around the seat frame components.
Also ordered two 18 x 24” Sonic Barrier 1 Acoustic Foam w/PSA 18 x 24 but haven’t figured out how to use them.
Now that tires are back on, I’ll dig out the sound meter to see if there is a measurable effect. Subjectively, there is an improvement.
Does anyone have suggestions on what material to use on the vertical kick panels underneath the seat? And what to use on the floor?
