Life-of-Vehicle Acoustic Protection for Microphones & ADAS
Crystal-Clear Sound with IP6K8 Protection — From −40°C to +105°C
Gore automotive acoustic vents deliver minimal insertion loss across the critical frequency range while keeping dust, water, and automotive fluids out of externally-mounted microphone and sound-monitoring assemblies throughout the vehicle's service life.
As vehicles become rolling computing platforms, the quality and reliability of acoustic sensing has become mission-critical. ADAS noise-cancellation systems, emergency siren detection for autonomous vehicles, and Mobility-as-a-Service (MaaS) sound-monitoring all depend on microphones that stay clean, responsive, and sealed — for the full life of the vehicle. Gore automotive acoustic vents use hydrophobic and oleophobic ePTFE membranes to block liquid water ingress to 2 meters/1 hour (IP6K8) while maintaining less than 2 dB insertion loss up to 1.5 kHz and less than 3 dB up to 5 kHz. Available as pressure-sensitive adhesive patches (AVS 700 and AVS 701) for direct PCB or housing application, these vents are IATF-certified and PPAP-documented for automotive supply chain integration.
Why Choose Gore Automotive Acoustic Vents?
Minimal Acoustic Insertion Loss
The Gore ePTFE membrane is acoustically transparent to the frequencies that matter most. With less than 2 dB insertion loss through 1.5 kHz and less than 3 dB through 5 kHz, ADAS sound-processing algorithms receive clean, unattenuated audio — critical for accurate siren detection, noise cancellation, and voice command systems.
IP6K8 Water & Dust Ingress Protection
Externally-mounted vehicle microphones face rain, car washes, and road spray throughout their service life. Gore's hydrophobic and oleophobic membrane blocks water ingress at 2 meters depth for 1 hour and provides complete dust exclusion — all without degrading acoustic transmission.
Life-of-Vehicle Durability
Automotive microphone assemblies are not serviceable components — they must perform reliably from day one through the full vehicle service life. Gore acoustic vents are validated through thermal shock, fluid exposure, salt spray, and vibration testing per IATF standards, ensuring consistent protection without maintenance.

Frequently Asked Questions
How does the Gore acoustic vent maintain IP6K8 while allowing sound through?
The ePTFE membrane has a pore structure that is permeable to pressure waves (sound) but impermeable to liquid water. The hydrophobic surface treatment causes water to bead and run off rather than penetrating the membrane, while the acoustic opening remains transparent to airborne sound at the frequencies used by automotive microphones.
What is the difference between the AVS 700 and AVS 701?
Both are pressure-sensitive adhesive acoustic vents with the same acoustic and IP performance. The AVS 701 is the reel-compatible variant designed for automated pick-and-place manufacturing processes, while the AVS 700 is configured for manual installation. Contact RSTECH Electronics to determine which format suits your production line.
Are these vents suitable for exterior-mounted ADAS microphones exposed to high-pressure washing?
The IP6K8 rating covers immersion to 2 meters for 1 hour, which addresses most water exposure scenarios. For applications exposed to direct high-pressure washing (IP6K9K requirements), Gore's automotive electronics vent series may be more appropriate — contact RSTECH to discuss your specific IP requirement.
Can RSTECH Electronics provide PPAP documentation for these parts?
Yes. As Gore's authorized representative in Israel, RSTECH Electronics can supply the full PPAP documentation package required by automotive tier-1 and OEM quality systems, including dimensional reports, material certifications, and process capability data.
