Acoustic camera Mikado

1920 x 1080handheldportable

Overview
The handheld soundcam Soundcam Mikado is a mobile all‑in‑one solution for diagnosing noise and vibration sources. The wireless, battery‑operated device enables measurements almost anywhere and provides on‑site acoustic data acquisition, analysis and visualization.

Includes

• Microphone array
• On‑board data recorder (DMC402L)
• Tablet with NoiseImage Mobile software

Mobile Soundcam Mikado
This mobile system is designed for fast troubleshooting of sound and vibration issues. Flexible measuring positions and angles permit rapid localization of noise sources using acoustic signals. The handheld device integrates acoustic data acquisition, onboard recording and analysis workflows. The recorder processes 96 digital microphone channels at up to 48 kS/s. Four isolated differential digital inputs allow synchronised acquisition of additional sensors. Use NoiseImage Mobile for post‑processing and correlation of extra sensor data with acoustic recordings. The exchangeable Li‑ion battery and Microsoft Surface Pro tablet provide fully autonomous operation.

System Details

• Microphone Array: randomized, algorithmically optimized microphone positions; 96 digital MEMS microphones over a 35 cm diameter surface.
• Data Acquisition: onboard via DMC402L data recorder developed by gfai tech.
• Sound Analysis: real‑time and post processing on Microsoft Surface Pro using NoiseImage Mobile; full data export to NoiseImage workstation.
• Power: exchangeable Li‑ion battery (Bosch system), approx. up to 3 hours runtime per battery.
