Spatial Noise Cancellation Progress

Our product development is divided into 4 phases after a basic setup:
Noise masking (equivalent to white noise machines)
Noise cancellation at a point (equivalent to headphones)
50% noise reduction
95% noise reduction
Noise cancellation via two dimensions shield (equivalent to a very thick wall)
Noise cancellation in three dimensions (equivalent to a room)
10 ft x10 ft x10 ft room size
20 ft x20 ft x15 ft room size

Progress presented in reverse chronological order

Phase 2, Milestone 1 - Noise cancellation at a point with 50% noise reduction

Ambient noise is 20 dB (average)
Noise source increases noise reading to 70 dB (removing ambient noise, this is 50 dB)
After applying noise cancellation, the reading is 45 dB (removing ambient noise, this is 25 dB - reduction of 50% from the 50 dB noise source)
