Pampas Grass: Pruneback Really Necessary?

Does anyone in the Deep South have experience with Pampas Grass that does not get cut back? Are there viable alternatives to pruning?

We moved away from Madison Mississippi, in part, because of an ongoing problem with noisy people a few blocks away from our house (rock-concert-size speakers/band 'ambient' 'hum' anytime the power to the things is even connected...a "hum" that travels for blocks). Possibly, the criminals are trading....ahem...."romantic favors"...with someone in 'authority' (We assume someone crooked in some branch of Law "enforcement"...but who knows?), and nothing short of a Mafia hit is going to stop them. Fat chance of that, because nobody in that neighborhood is worth over a hundred million. Unfortunately, everyone 'connected' lives on huge estates in richer parts of the city, and is unaffected by the problem. Mere Physicians and Attorneys cannot just have people 'disappeared', and so are faced with either shielding their houses from the noise, or moving away, as we did.

Our former neighbors are impressed with our noise abatement plantings (and our draperies, interlined with Industrial Noise-Control Blankets...and the half-inch Polycarbonate we added at the windows)), and are still calling for advice. We mostly bermed, put in an Ivy-sheathed garden wall or two, and planted Clumping Bamboo. But we did put in a few clumps of Pampas grass, which because it puts a lot of carbon (dense leaves) at ground level, is ideal for intercepting and absorbing Infrasonic Soundwaves as they travel near the ground. Now, the young Surgeons who bought the house, and neighbors who are planting whole hedges of Pampas Grass, in desperation, would like to leave the clumps unpruned, because they need the noise abatement in Winter, too. Local 'experts' only know what they were taught in school, and all insist on severe yearly pruning.

Does anyone know what will happen, in the Deep South, if Pampas Grass is not cut back? Would cutting it back only to three or four feet be sufficient? Would sprinkling a Nitrogen-rich fertilizer into the center of the clumps accelerate decomposition of the old leaves, and thus serve as a substitute for pruning/burning?

I was hoping one of our southerners would pipe up.

In the deep south, Pampas Grass should be evergreen, so pruning the whole thing down shouldn't be needed. I expect you could get away with cutting out dead leaves and spent plume stalks.

As I suspected! Thank you!
