Hushline Acoustic Fencing · Ashvale & the Corridor towns · Since 2009
We sell quiet — measured in decibels, guaranteed on paper.
Why a barrier is not a fence
The quiet, quantified
A privacy fence stops eyes; sound walks through a gap the width of a coin. A barrier does three things a board fence cannot: mass to blunt the energy, height to break the line-of-sight to the source, and seals at every seam so the noise cannot pour through the joints. We measure your porch before we quote any of it.
What we do
Three barriers, one measurement
Reflective mass wall — from $96/ln ft
Twenty-eight-millimetre composite mass panels on steel I-beam posts at six-foot centres, built to nine feet with an acoustic seal at every seam. It reflects the road back at the road — no line-of-sight, no path for the sound but over the top, and the top is high.
Absorptive louver line — from $118/ln ft
For courtyards where a reflective wall would only bounce the highway at your own windows: mineral-wool-cored blades angled to swallow the energy instead of returning it. The line for the yard that is surrounded on two sides by the noise it is escaping.
Berm-and-line — from $52/ln ft
An earth berm with a barrier riding its crest, where the yard has the room for it — the oldest acoustic technology there is, and still the best-looking. Earth is free mass; the line adds the height the berm cannot. Quoted off the same decibel walk as everything else we build.
Three porches, before and after
The Ashvale ledger, read aloud
Real readings from Corridor lines, metered at the porch rail at evening peak, thirty days after handover. A ten-decibel drop reads to the ear as roughly half the loudness — which is the difference between noticing the road and forgetting it.

How it goes
Decibel walk to quiet porch
The same sequence on every job — the only variable is your project.
Day 1
The decibel walk
The meter goes on your porch rail at evening peak, twice, an hour apart. Free, and the number is yours whoever builds the wall — it is the only honest starting point there is.
Week 1
The engineering sheet
Wall height by the line-of-sight rule, panel mass, post schedule to the frost line, and the predicted after-reading with the guarantee attached. One page, every number, one fixed price.
Set day
Posts & footings
Steel I-beam posts augered to the county frost line in concrete, rails shimmed level between them. The cure day is on the schedule before a panel arrives.
Build days
Panels & seals
Mass panels lifted into the run with an acoustic seal at every seam — the gap that whistles is the gap that ruins the arithmetic, so the seal gun is as important as the crane.
Day 30
The after-reading
The meter comes back to the same porch rail, same hour, same season of traffic. The reading goes in writing beside the guarantee — and in two hundred and ten lines it has never missed.
The first Saturday we forgot the highway was there. We were three weeks into the wall, coffee on the porch, and I realised what I was hearing was a bird I had never met in nine years of living here. The meter said −14; the bird was the number I understood.
We had the house on the market for a season with the road as the sticking point on every viewing. The louver line went up in April, the after-reading went in the listing, and it sold at the second open house — to the buyers who stood on the porch first.
Three companies quoted us tall wooden fences with confident adjectives. Hushline was the only one that brought a meter. The berm-and-line cost less than two of the wooden quotes and the porch is a place again instead of a decision.
The school wanted the road gone and the neighbours wanted their garden view kept, and the cedar-faced mass wall did both — the committee approved a drawing that read like landscaping and performed like a wall the inspector would recognise.
Before the walk
The quiet questions
What every Corridor porch asks eventually, answered with meters and mass rather than adjectives.
Doesn’t any tall fence block noise?
It blocks some, and a board fence is mostly optimism — sound pours through board gaps and over a six-foot line with barely a dent. Mass, height and seals are the three levers, and the meter is the only honest judge of whether anyone pulled them.
What height does a barrier actually need?
The rule of thumb is the line-of-sight rule: break the view from your ear to the source and the maths starts working, which on flat Corridor ground means nine feet. Every extra foot buys about one more decibel; the engineering sheet prices each of them.
Will it stop the trains, or just the road?
Rail noise is lower-frequency and harder — the honest expectation is −7 to −9 dB rather than the −12 to −14 a road line delivers. We measure the source you actually hear before we promise anything, and the contract carries the number we can defend.
Cedar versus engineered mass — the honest comparison?
Cedar privacy runs around $34 a foot, looks wonderful and buys you two or three decibels. Engineered mass costs roughly three times that and delivers the double-digit number. For the yards that want both, a cedar face on a mass core adds about $24 a foot — the garden view with the meter reading.
