Vehicle in wind tunnel

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:

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
