Typical noise levels near small aircraft engines: 85–110 dB

85 dB = threshold where long-term exposure can cause hearing damage100+ dB = damage can occur in minutes to hours depending on duration

Custom earplugs typically reduce noise by 20–30 dB (NRR range)This can bring exposure from ~100 dB → ~70–80 dB (within safer limits)

You can still hear:

  • Intercom systems
  • Radio calls
  • Important environmental cues

Cabin noise ~80–90 dB over long durations Pressure changes during ascent/descent
Key advantage: Pressure-regulating filters reduce discomfort and fatigue.

Custom earplugs reduce noise by ~20–30 dB (NRR lab rating)
Real-world reduction: typically 10–20 dB
Perceived noise drops significantly (e.g., 80 dB → ~60–70 dB range)
Environment feels much quieter and more manageable
