Acoustic Barriers
HERMEQ supplies acoustic barriers and acoustic quilts that control noise on construction sites, at industrial facilities and at live events. The range is built around the Echo barrier family: temporary noise control products that hang on temporary fencing or stand on their own, and go up quickly. The Echo acoustic quilts and fence-mounted barriers absorb site noise through a layered sound-absorbing core behind a PVC outer face, and a single panel hangs in minutes. They are water resistant, UV resistant and fire rated, so the same barriers can serve a two-week utility job or a build that runs through several seasons.
Acoustic blankets, sheeting, screens and enclosures
The range falls into three groups: barriers that hang on a fence or scaffold already on site, screens that stand on their own wheeled frame, and enclosures that close in the noise source on every side.
Acoustic blankets for temporary fence panels
Acoustic blankets, also sold as sound blankets or acoustic fence panels, are the standard format for lining a site boundary: each one hangs on a single bay of temporary fence, and the run builds up bay by bay. The Echo H9 acoustic barrier suits standard six-foot fence lines. Where houses or offices overlook the site, the Echo H9X acoustic barrier for 8 ft fences adds height. The Echo H10 acoustic barrier is a lightweight panel for rotating work zones and multi-phase builds, where the line is taken down and rehung often.
Full-panel acoustic quilts
A full-panel quilt covers a whole 12 ft temporary fence panel with one unit, so a long boundary takes fewer pieces to hang, count and take down. The Echo H8 acoustic quilt suits large infrastructure, utility and demolition projects with long fence lines, where installation time across the whole run matters more than the ability to move single narrow panels.
Acoustic sheeting for scaffolding
Roll-format scaffolding acoustic sheeting fixes to the scaffold face and carries noise control up the height of a building under construction or repair, above the reach of any fence line. It comes in two acoustic grades, so the sheeting can be matched to the reduction a project specification asks for.
Fence extensions for noise above the barrier
Sound from a source that stands higher than the barrier, such as a generator or tall equipment, travels over the top of the run. The acoustic fence extension mounts on fences, barriers and structures over about 5 ft tall, either upright to add height or overhead, and closes that path without rebuilding the line beneath it.
Mobile acoustic screens
A mobile acoustic screen stands on its own wheeled frame, folds and rolls for transport, and moves with tasks that change position through the day, such as cutting or breaking at several points on one site. Choose it where there is no fence to hang a panel on, or where the noisy task is too short to justify moving a fence line.
Acoustic enclosures for cutting, drilling and repair work
An enclosure surrounds the work itself, so it contains dust and debris along with the noise. The portable acoustic enclosure comes in compact and large sizes on locking wheels, with see-through mesh panels for visual checks and airflow, and suits sidewalk cutting, grinding, HVAC and utility box work in busy streets. The Echo H20 acoustic enclosure is built for high-rise projects and confined work areas.
Generator enclosures
Small generators and power units run for hours at a fixed point. The generator acoustic enclosure folds for one person to carry and sets up as a full enclosure or as a three-sided barrier that leaves one face open for refueling and maintenance.
Sound barrier fence or enclosure at the source
Line the perimeter when the noise comes from the whole work area, and enclose the source when it comes from one fixed point. A perimeter run of acoustic panels on temporary fencing suits long boundaries next to homes, roads and occupied buildings, where excavation, demolition and deliveries produce noise across the entire site. A fixed, concentrated source, such as a generator, a saw cutting station or a utility box under repair, belongs in an enclosure.
Sound spreads outward from its source, so a barrier placed close to it has to cover a far smaller area to block the same sound. Tasks that move through the day, such as cutting at several points along a curb line, take a mobile screen that follows the crew. Larger sites often use both approaches, with enclosures on the loudest fixed equipment and a perimeter run along the boundaries that face neighbors.
Noise barriers for demolition, roadwork and events
Construction and demolition next to homes
Demolition and building work produce noise across the whole site for weeks at a time, so the side of the boundary facing houses or apartments needs a continuous run at full fence height with no open bays.
Road and rail work
Road surfacing and rail work advance along a corridor, sometimes by a block or more in a shift, so the barriers have to come down and go back up as the work front moves. Lightweight fence-mounted panels and wheeled screens are the formats that keep pace with it.
Street, utility and MEP repairs
Sidewalk cutting, utility box work and mechanical, electrical and plumbing repairs take place with pedestrians, storefronts and traffic on every side. A compact enclosure holds the noise, dust and debris at the point of work on a small footprint and keeps people walking past out of the work area.
Events and temporary power
Festivals, outdoor events, emergency repairs and backup power installations depend on generators that often run late into the evening near audiences or residents. A generator enclosure contains that noise at the unit itself and moves with it from one event or repair site to the next.
What makes a temporary sound barrier work
Fence height and panel coverage
The barrier format has to match the structure it hangs on. Check the height and width of the temporary fence panels or scaffold on site before ordering: a panel shorter than the fence leaves an open strip, and one sized for a different panel width leaves gaps between bays.
Gaps, overlaps and the top of the run
Sound passes through any opening, so panels should overlap at their edges and reach down to ground level, with corners and gates closed off. A fence line coupled panel to panel with no breaks, using the fittings in temporary fencing accessories, gives the barriers a continuous line to hang on. Where the source stands above the fence, the run needs an extension on top.
Lab figures and site results
The range is lab-tested at up to 43 dB of noise reduction, and the H20 enclosure is listed at up to 20 dB measured on site. The two figures measure different things: the lab figure rates the barrier material under controlled conditions, while the site figure is what a meter records with real gaps, reflections and distances. On a jobsite, the result is decided by how continuous the line is and how far it rises above the line of sight between source and listener.
Weather and fire ratings
Most Echo products are rated against heavy spray and high-pressure water, rated for long-term UV exposure and rated to -40°F, which covers outdoor work through winter and summer. ASTM E84 fire testing applies across most of the Echo range, and each product page lists the fire testing for that product where a specification or permit calls for it.

Frequently Asked Questions
Yes. A barrier placed between a noise source and the people who hear it blocks the direct sound path, and the absorptive face of the Echo range takes in sound instead of reflecting it back across the site. The result is a lower noise level beyond the barrier and less reflected noise for crews working inside it.
As close to the noise source as the work allows, because a barrier near the source blocks a wider spread of sound for the same height. Where that is not practical, the next best position is close to the homes or buildings being protected. A barrier midway between the two gives the least reduction.
Yes. The fence-mounted Echo panels are light enough for one person to lift and hang, and several are listed for one-person setup in around 30 seconds per panel. The fence extension is the exception and is installed by two people.
Fence-mounted panels fix to the fence mesh and frame with standard fence hooks or cable ties, and no tools are needed. Some panels also carry a security cable for anti-theft protection on long jobs.
Yes. The panels, screens and enclosures are made for repeated deployment, and a barrier taken down at the end of one job can go straight onto the next fence line.
