Linear 8-Microphone Array Module, Near-field Directional Pickup + DNN Deep Noise Reduction + AEC Acoustic Echo Cancellation

Product Overview

The spatial sound pickup module is a linear 8-microphone array audio solution, designed for industrial scenarios such as financial self-service terminals and smart business halls. Adopting beamforming technology for narrow-beam directional sound pickup, together with DNN deep noise reduction and AEC acoustic echo cancellation algorithm. Optimized for near-field voice interaction within 1m, it suppresses side & rear noise and audio crosstalk effectively. Plug-and-play modular structure supports fast integration. Industrial-grade wide-temperature hardware ensures stable continuous operation for self-service equipment, delivering clear two-way voice communication for VTM teller machines and bank counter terminals.

Key Features (5 Highlights）
1. 36° Narrow Beam Directional Pickup
36° (±18°) narrow beamforming accurately captures human voice from front, suppress interfering sound from side and rear directions, ideal for face-to-face counter interaction.
2. Stable Near-Field Pickup within 1m
Optimized for near-field human-machine interaction. Focus on target voice within 1 meter and filter far-field background noise, capture clean voice for users in front of counter or kiosk.
3. DNN Deep Learning Noise Reduction
Built-in DNN deep neural network noise reduction algorithm with up to 65dB noise suppression. Optimized for noisy business hall environments, reduce stationary and non-stationary background noise and improve signal-to-noise ratio.
4. AEC Acoustic Echo Cancellation
High-performance acoustic echo cancellation with ≥70dB echo suppression depth. Suppress speaker feedback and audio crosstalk to support smooth full-duplex two-way call without echo or howling.
5.Plug-in Modular Design
Plug and play, no heavy secondary development required. Accelerate prototype verification and shorten project cycle, easy for mass production integration and equipment maintenance.
