Comfort and noise track
Precise analysis of acoustic comfort
- 4,5 km length
- 4 lanes for noise measurement with 16 profiles (including whisper asphalt, smooth asphalt, rough asphalt, grooved concrete roadway, chipped concrete roadway, cross rails, cobblestones)
- Uneven road surfaces with various wave profiles, bumps, and rattle imperfections
- German concrete highway (replica of the A5, classic concrete slabs with expansion joints)
- Replica of the old Weisenauer Bridge
- Replicas of manhole covers and lids
- ISO 10844 asphalt
- Combination of various road surface types for noise evaluation
The comfort and noise measurement track offers the opportunity for both subjective evaluations and objective measurements of interior and exterior noise. Additionally, acoustic vehicle components are assessed for their noise signature, and compliance with legal noise limits is verified. Driving on this track allows for controlled investigations into the impact of different driving modes, such as comfort, sport, or race, on noise emissions and aspects like traction, front-end instability, and damping behavior.
