How can your innovation keep pace with the rapid change in today’s world?
PRECISION
IS WHAT WE DO
Aeroacoustics testing taken to a whole new level
Aeroacoustics testing pairs wind with microphones to allow us to measure the noise that’s created.
Understand the impact of wind noise and make informed design decisions in one of the quietest tunnels in the world, with real-time data output visualization and access.
That’s how HALO’s aeroacoustics testing brings value.
Efficiency at
every level:
Visual map
Software that creates a visual map of the sound level in real-time and in 3D
Efficiency at
every level:
Automation, no problem
Automated test sequences make your execution repeatable AND make tunnel time more efficient
Efficiency at
every level:
One of the world’s quietest
At 140 kph (87 mph) wind speed, the noise level in the test cell is less than 57 dBA
Efficiency at
every level:
Pinpoint exact noise sources
502-microphone acoustic array system and 54-microphone in-vehicle sound source detection system

Drag and tap to navigate facility
Control Room
- Spacious workspace to collaborate
- Windows and confidential outside area
- Kitchenette
Variable Nozzle
- 25 square meters = 250 kph (155 mph) wind speed
- 18 square meters = 310 kph (192 mph) wind speed
Heat Exchanger
- 10-50 degrees Celsius (50-122 degrees Fahrenheit)
- Maintains constant temperature
Settling Chamber
- Massive area behind the fan
- Allows airflow to settle before entering the test section
- Lowers turbulence level
- Allows quiet and uniform flow quality for good repeatability
3/4 Open Test Section
- 3 meters x 5 meters x 15 meters
- Acoustic environment: <57 dBA @ 140 kph (87 mph) wind speed
- 12 meter diameter turntable with 180-degree rotation
Fan
- 5 Megawatts (6700 HP)
- Diameter = 8 meters
- 12 Carbon Fiber Fixed-Pitch Blades
- Max rpm ≈ 250 @ 310 kph
- Inspection completed each day
Turn 4
- Final turning vanes
- Honeycomb screen to take out rotation in airflow
- Final screen equalizes flow and creates low turbulence level
Turn 2
- Before reaching the fan
- FOD (foreign object and debris) screen to protect the fan from any flying objects
Turn 1
- Turning vanes covered in acoustic panels
- Expand the airflow quickly to prevent flow separation
We’re here to take your wind tunnel experience to the next level.
