How to evaluate Baby Sound Module performance

2025-07-31
Latest company news about How to evaluate Baby Sound Module performance
The following is a complete technical indicator system and test method for evaluating the performance of the Baby Sound Module:
I. Core Function Testing
Cry Detection Accuracy
  • Tested using a standard infant cry database (such as the Baby2023 dataset), the accuracy for classifying cry types such as hunger and pain must be ≥95%.
  • Ambient noise suppression must meet the ISO 7779 standard test, maintaining a detection rate of 90% or higher even in 60dB background noise.
Response Performance
  • End-to-end response latency must be <300ms (from sound acquisition to triggering an action).
  • Supported audio formats must include MP3, WAV, and FLAC, with compatible bit rates of 16-320kbps.
II. Hardware Performance Indicators
Test Items Standard Requirements Test Tools
Microphone Sensitivity ≥-38dBV/Pa @1kHz Sound Level Meter + Audio Analyzer
Power Consumption <5mW in standby mode, <50mW in operation Digital Power Meter
Wireless Transmission Stability Signal attenuation ≤3dB within 10 meters Network Analyzer
III. Extended Function Verification
  • Multimodal Linkage: Tests protocol compatibility with devices such as cameras and smart lights. Linkage response error must be less than 1 second.
  • Data Analysis Capabilities: Run continuously for 72 hours to check for memory leaks. Crash rate should be less than 0.1%.
  • User Interface: Verifies app operational efficiency using Fitts's law. Key function triggering time must be ≤ 2 seconds.
IV. Special Scenario Testing
  • Extreme Environment: Verifies module reliability under 85% humidity and a temperature range of -10°C to 50°C.
  • Long-Term Stability: Simulates a 3-year usage cycle. Performance degradation should be less than 15%.
  • Safety Certification: Must pass FCC/CE radio frequency certification and EN71-1 toy safety standards.
