Every energy asset class has its own noise profile, and the mitigation approach only works if it’s designed around the real source. Here’s what typically drives noise across the sector:
| Energy Asset | Primary Noise Sources |
| Battery Energy Storage (BESS) | Cooling and HVAC systems (run continuously, day and night), inverters and power control units (steady operational hum), transformers (low, constant hum) |
| Solar Power Plants | Tracker motors (intermittent), central inverter units (continuous during generation), plus any co-located BESS equipment |
| Geothermal & Hydrothermal Plants | Turbines and generators, cooling towers, steam venting and pressure-release systems — often with a stronger low-frequency component than solar or BESS noise |
| Grid & Substation Infrastructure | Transformer hum (low frequency, hard to mask with standard barriers), switchgear, cooling fans |
BESS and solar projects require particular attention to continuous equipment noise, especially where energy infrastructure is located near residential areas or other sensitive receptors. The same source-specific acoustic planning approach can be applied to geothermal, hydrothermal, and grid-scale projects.
Within the energy sector, BESS and solar sites are where the noise-versus-compliance gap is best documented today:
| Source | Typical Output |
| High voltage substation transformer | ~90 dB LWA per unit |
| Central inverter / PCS unit | ~88 dB LWA per unit |
| Battery storage unit | ~80 dB LWA per unit |
| Medium voltage transformer | ~70 dB LWA per unit |
| Tracker motor (intermittent) | ~66 dB LWA per unit |
Night-time residential limits, by contrast, commonly sit between 35 and 45 dB, depending on jurisdiction and the land use around the site. That gap doesn’t close on its own, and it doesn’t close cheaply once equipment is already ordered and civil works are underway.
Proof: From the BESS & Solar Noise Control blog — on a recent BESS project sited near a rural residential area, Hushtec acoustic enclosures cut fan and HVAC noise by more than 18 dB(A), bringing site emissions well below the project’s 40 dB night-time limit. The reduction held because the enclosure was designed into the site layout from day one, not retrofitted after a complaint.
| Noise Source | Hushtec Product |
| Site perimeter / BESS or plant compound (permanent, slim-profile) | Hushtec AcoustiShield |
| Site perimeter / BESS or plant compound (permanent, heavy-duty / extreme conditions) | Hushtec Hushwall Permanent System |
| Temporary deployment during construction, commissioning, or staged builds | Hushtec Portable Hushwall |
| HVAC, cooling fans, battery cabinets | Custom Acoustic Enclosures (built from Hushtec Custom Shroud) |
| Generator or transformer shrouding | Hushtec Custom Shroud, wrapped with Hushtec MLV (Mass Loaded Vinyl) |
| High-attenuation perimeter barrier where maximum reduction is the priority | Hushtec STC24 Panel or Hushtec Premium Barriers |
| Moderate/temporary site barrier, lighter footprint (e.g. laydown or construction phase) | Hushtec Performance Barriers |
| Bespoke enclosure geometry for irregular layouts or non-standard equipment | Hushtec Signature Series |
Any site with continuous mechanical or electrical equipment near a residential area or sensitive receptor — solar farms, BESS compounds, geothermal and hydrothermal plants, and grid substations all fall into this category.
Night-time residential limits commonly fall between 35 and 45 dB, but the exact figure depends on your local standard and the land use around the site. A Hushtec site assessment confirms the number that applies to your project.
Yes. AcoustiShield and the Hushwall Permanent System are both modular, so a wall section extends around an expanded compound without a custom fabrication run.
AcoustiShield is engineered against your site’s actual component noise data, not a generic barrier height, and is weather-rated for long-term outdoor deployment. For sites that need a heavier-duty permanent wall, the Hushwall Permanent System covers extreme-condition installs, and Portable Hushwall handles temporary or phased deployments without permits or foundations — all three build from the same site assessment.
Yes. Site assessment and acoustic modelling are part of the same service as design and installation, handled by one team.
Yes. Retrofit enclosures and barriers are common after a complaint or compliance notice, and the process starts with the same site assessment used for new builds.

"Hushtec panels are awesome! They helped us better manage noise on site, improved privacy and safety for our crew, and gave us free branding with our logo printed on them. Highly recommend."
" I used to think noise barrier blankets didn’t work until I tried the Hushtec panels. These reduced our noise on-site immediately, which enabled us to continue works throughout the night on an urgent project, saving our customer thousands and helping complete the project before scheduled. The team is also very knowledgeable and helpful, couldn’t ask for more. "
"We recently installed the Hushtec Acoustishield Wall around a large generator compound,and we couldn't be more impressed with the results. The Acoustishield system was by far the easiest noise reduction system we've ever worked with-quick to assemble and straightforward to install. Beyond its ease of use, the performance has been exceptional. It achieved an impressive 31dB noise reduction from our containerized generators, far exceeding our expectations. The quality and effectiveness of the Acoustishield Wall have set a new benchmark for us in noise control solutions. We highly recommend Hushtec for any project where noise reduction is critical."
Our products and service consistently meet the high expectations of leading companies in construction, manufacturing, and demolition, earning their ongoing trust and partnership.
