Product overview
Type 4949 is an automotive surface microphone designed to measure true surface pressure during wind‑tunnel tests and in confined spaces. It is a surface‑mountable special acoustic transducer intended for accurate surface pressure and airborne‑surface coupling measurements on vehicle panels and components.

Key features

• Designed for true surface pressure measurement on vehicle surfaces
• Surface‑mountable special microphone for direct contact with the tested surface
• Optimised for wind‑tunnel and aeroacoustic testing
• Suitable for confined or hard‑to‑access measurement locations
• Connection indicated: 1 coaxial cable

Applications

• Wind‑tunnel aerodynamic and aeroacoustic testing
• Surface pressure mapping on vehicle panels and components
• NVH and acoustic measurements in confined spaces where surface mounting is required
