Wind-resistant structure
Windproof foam + cavity seal design blocks turbulent airflow from reaching the diaphragm, significantly reducing wind noise generation. Enhanced sealing also prevents dust and moisture ingress.
Mid-low sensitivity selection
Target: -50dB ~ -70dB. Lower sensitivity prevents wind turbulence from being amplified while maintaining clear voice capture for close-talking applications like helmets and headsets.
Bidirectional / Unidirectional pattern
Bidirectional mics pick sound from front and back while rejecting sides — ideal for aviation headsets where the mic is positioned at the mouth. Unidirectional mics focus on the speaker's mouth, rejecting ambient wind from other directions.
Application-specific optimization
Motorcycle helmets: Uni-directional electret with voice-band boost for close
talking.
Aviation headsets: Bidirectional or dynamic uni-directional designs for cockpit
environments.
Marine radios: Dynamic uni-directional with moisture resistance.
| Parameter | Requirement | Why It Matters |
|---|---|---|
| Polar Pattern | Bidirectional / Unidirectional | Focused pickup patterns reduce wind turbulence pickup compared to omnidirectional |
| Sensitivity | -50dB to -70dB (mid-low range) | Lower sensitivity reduces amplification of wind noise; ideal for close-talking applications |
| SNR | ≥ 57dB (electret models) | Higher SNR ensures cleaner voice extraction in windy conditions |
| Environmental Protection | Dynamic models offer inherent moisture and dust resistance | Ensures long-term reliability in outdoor, marine, and cockpit environments |
