  * Change the accelerometers to beam direction
Line 14: Line 15:
  * Slow Environmental Monitor should monitor not only day but also week/monty -> Already monitored
Line 15: Line 17:
  * Can anyone use spectrogram tool? yes
  * Make frame file with selected channel -> Another issue
Line 17: Line 21:
  * Not distinguish coherence and incoherence for acoustic injection
  * Check different amplitude injection and check the linearity of the significance
  * Use aqccelerometer instead of the microphone
  * Reducing the uncertainty for the injection point. Wide injection->local injection
