During their design validation process, a well-known smartphone company discovered that their existing acoustic vent failed the product waterproofing test, which caused catastrophic damage to their device. The waterproofing problem was so severe that many of the devices subjected to the design validation process were damaged beyond repair. Therefore, the OEM was unable to guarantee the reliability of the product.

The Vice President of the company himself called Gore, as he was confident that we could offer a reliable alternative to meet all of their performance and quality requirements. And he was to be proven right.


In little to no time, our application engineers were able to evaluate the requirements of the device and introduce a viable alternative product to solve the water ingress problem and suit the client’s needs. The solution? The well-established GORE® Acoustic Vent product model GAW333 with effective IPX8 water resistance. Gore’s ability to provide a product with reliable IPX8 protection and optimized acoustic performance was essential in delivering a trustworthy fix for the client.

But the solution to a problem lies not only in supplying the right product. Well-aware that a badly installed vent inevitably leads to water ingress no matter the quality, our experts provided an insightful overview of the installation process to enable the precise and accurate implementation of GORE® Acoustic Vent GAW333 by the OEM. Gore’s understanding of the client’s manufacturing and installation procedures, as well as the Gore product, were utilized to prevent further catastrophic water intake.

Moreover, through this close collaboration with the client, the Gore team was able to facilitate unique part design with excellent handling and fitting characteristics. This optimized the overall acoustic performance, skillfully balancing the trade-offs between water protection and sound quality.

The Vent: GORE® Acoustic Vent GAW333

The vent used here was the GORE® Acoustic Vent GAW333. It is available with inner and outer dimensions of 1.6 and 3.2 mm or 2.0 and 3.6 as well as a reference thickness of 0.36 mm or 0.31 mm. Suited for shallow immersion, this standard part provides an IP68 rating and an insertion loss of less than 1.3 dB at 1kHz. For more information on our standard acoustic vents please visit

Our deep understanding of the client’s applications and product requirements facilitated the development of a solution that satisfied all aspects of the client’s requirements and even exceeded their expectations. Not only did the Gore engineers reliably solve the client’s water ingress problem, they also helped the smartphone OEM optimize the overall acoustic performance of their devices.

With our help, the smartphone OEM was able to 

  • eradicate the water ingress problem quickly.
  • guarantee immersion protection for 30 mins in 2.0 m of water.
  • optimize acoustic performance of their smartphones.
  • minimize yield loss for the device by adapting Gore’s installation process.
