ANR Module - Active Noise Reduction

ANR Module

Our ANR Upgrade Kits are made of the finest components and materials available. After construction, all ANR modules are thoroughly tested for quality and performance to ensure reliable service for years to come.
Each module consists of:

- Electret Microphone - Picks up ambient noise within the ear cup cavity.
- Circuit board - Processes ambient noise and generates a duplicate wave, which is shifted 180 °
- out of phase from the sampled unwanted noise.
- Upper Speaker - Emits normal audio signal without modification.
- Lower Speaker - Emits the generated ANR wave to reduce noise.
- Noise Reduction Bandwidth: 20 Hz to 600 Hz.
- Decibel Reduction: 15-17 dB active noise attenuation1 at 200 to 300 Hz.


Power Source:
The ANR system requires 9 volt battery powered DC.


Notes:
1) Total noise attenuation you receive will depend on your headset, quality of fit, and ear seals used.
3) If the battery goes dead while the headset is in use, the normal unmodified audio signal continues to be received. Only the ANR function of the system is lost.
