Active Noise Cancelling Testing (ANC testing)

Noise cancelling performance:

  • With background noise on, noise sources may include:
    • Travel noises related to airplanes, trains, automobiles, etc.
    • Interior noises related to call centers, pub, cafeteria, etc.
    • Exterior noises related to train station, roadways, etc.
  • Spectral response and levels

Communication/Media playback performance with ANC on:

  • Listening effort (LE-MOS)
  • Speech quality MOS (S-MOS)
  • Noise quality MOS (N-MOS)
  • Frequency response and levels

Talk-through performance:

  • Listening effort (LE-MOS)
  • Frequency response and levels
