Noise Attenuation (Passive)


The H20-16 headset achieves its noise reduction through passive means, utilizing the design of its ear cups and the materials used in its construction. The Flo-Fit Gel Earseals (part number 40243G-05) play a crucial role in creating a tight seal around the ears, effectively blocking out ambient noise and ensuring a quieter cockpit environment.


Over time, the effectiveness of noise attenuation can degrade as the ear seals wear out. Pilots may notice an increase in ambient noise, indicating it's time to replace the ear seals. Regular inspection and replacement of these components will maintain the headset's performance and your comfort.

What's the difference between the David Clark H20-16 and H20-10?

The H20-16 and H20-10 are both part of David Clark's lightweight headset series, but they cater to slightly different needs. The H20-16 is designed with a focus on comfort and noise isolation, featuring the Flo-Fit Gel Earseals for superior sealing and comfort. In contrast, the H20-10 offers a more basic design with standard ear seals.


Parts Compatibility

  • Both models share the M-7A Electret Microphone (09168P-33), ensuring clear communication.
  • The headband assembly (18900G-73) is compatible across both models, allowing for easy adjustments.
  • Communication cord assemblies differ, with the H20-16 using the 18028G-26 and the H20-10 using a different configuration.

If you're looking for enhanced comfort and noise isolation, the H20-16 is the better choice, while the H20-10 remains a reliable option for those who prefer a simpler setup.
