Ground operations noise doesn’t come from one source — it moves around the apron and hangar depending on what’s being worked on. Here’s what typically drives it:
| Ground Operations Zone | Primary Noise Sources |
| Ramp / ground run-up areas | Full-power engine ground runs (approx. 130–140 dB at operator position), exhaust and intake noise |
| Taxiway / apron movement | Taxi operations and idle-power engine noise (approx. 100–110 dB), ground power units, tugs |
| Hangar interior | APU testing, riveting and fastening during assembly/repair, reverberation off hard surfaces (approx. 90–105 dB) |
| Ground support equipment (GSE) | Ground power units, air conditioning carts, air start units — continuous operation near parked aircraft |
Figures are representative operator-position readings drawn from aviation industrial hygiene and hearing-protection references; actual levels vary with aircraft type, engine configuration, and ground conditions.
Ground operations noise in Australia is governed by the Civil Aviation Safety Authority (CASA) and Airservices Australia at the aviation level, with facility and community noise addressed through state and territory EPAs (e.g. NSW EPA, EPA Victoria). Airport-level noise is typically managed through the National Airports Safeguarding Framework (NASF), and occupational hearing conservation for hangar and ramp workers falls under Safe Work Australia and state WHS regulators.
| Source | Typical Operator-Position Level |
| Full-power ground engine run-up | ~130–140 dB |
| Taxiway / idle-power operations | ~100–110 dB |
| Hangar interior (APU testing, riveting) | ~90–105 dB |
| Ground support equipment (GPUs, tugs, air carts) | Varies by equipment — confirmed via site assessment |
Curfew violations aren’t just a community relations issue — they’re a direct constraint on how much maintenance work gets done in a day. That gap doesn’t close by relocating equipment; it closes with acoustic mitigation designed around where the noise actually happens.
| Noise Source | Hushtec Product |
| Ground run-up / apron operations | Hushtec Portable Hushwall (reconfigurable, redeployable) |
| Ground support equipment (GPUs, tugs, air carts) | Hushtec Custom Shroud |
| Hangar interior reverberation / riveting noise | Hushtec STC Panels, absorption panels |
| Temporary noise control during maintenance events | Acoustic Tent range |
| [In development] Apron-rated ground run-up barrier | Stage 4 product — not yet available |
Test cells contain a jet engine at full power inside a fixed hemi-anechoic chamber for certification-grade testing. Ground run-up and hangar noise control manages lower-intensity, mobile noise sources — APU testing, GSE, riveting — using modular barriers that redeploy as operations change.
Yes — Portable Hushwall systems are designed to be redeployed, unlike fixed chamber infrastructure, which makes them a better fit for ground operations that don’t stay in one place.
Curfew and operating-hour restrictions vary by airport. For example, Sydney Airport operates under a legislated curfew (Sydney Airport Curfew Act 1995) restricting operations between 11pm and 6am. Check the specific noise abatement procedures for your airport, and a Hushtec site assessment can confirm how ground noise mitigation supports your compliance position.
It depends on the specific equipment and barrier configuration — book a ground operations noise assessment for numbers specific to your site.
An apron-rated version — built for jet blast, FOD safety, and fuel exposure — is currently in development. Contact us to discuss your site’s requirements and pilot opportunities.
Yes. Retrofit deployment is common after a curfew issue or community complaint, and the process starts with the same site assessment used for new facilities.

"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 EchoShield Wall around a large generator compound,and we couldn't be more impressed with the results. The EchoShield 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 EchoShield 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.
