Durable Ingress Protection Against Dust, Dirt, Water, Auto Fluids and Oils
  • Pressure-sensitive adhesive vent bonds securely, to seal microphone ports reliably
  • Sized for design flexibility: fits acoustic openings up to 2.5 mm diameter
  • IP6K8 dust and water (2 meters/1 hour) ingress protection per ISO 20653
  • Operating temperatures: -40 °C to +105 °C
Minimal Insertion Loss & Excellent Distortion Resistance at High and Low Temps
  • < 2 dB change through 1.5 kHz and
  • < 3 dB change through 5 kHz*
Life-of-Vehicle Protection in Temps -40 °C to +105 °C
  • Validated for automotive durability
  • IATF-certified manufacturing

* Tested using analog MEMS microphone, 1 mm from vent with 1 mm diameter acoustic opening. Design of assembled device will affect performance.

Acoustic Vents for Exterior-Mounted Microphones in Automotive and Mobility Applications

GORE Acoustic Vents are designed to protect externally-mounted microphones used in vehicle sound monitoring / communications and noise cancellation systems. 

  • Ideal for external sound-monitoring devices used in ADAS, MaaS*, and other outdoor sensing technologies.
  • For interior microphone applications, please contact your Gore representative.

* Advanced Driver-Assistance Systems, Mobility-as-a-Service

We commit to every customer that “our products will do what we say they will do" — and we stand behind that promise with our worldwide resources, expertise, and quality processes. 

Easy installation, long-lasting quality

These all-membrane vents (with no backing material) are designed for manual installation on substrates that include all typical housing metals and plastics, and all typical circuit board materials.

Our hydrophobic and oleophobic vents provide very low insertion loss through the audible frequency range, as well as life-of-vehicle protection against contaminant ingress — even in challenging on-road environments.
