Active Noise Control over Space: A Subspace Method for Performance Analysis
Round 1
Reviewer 1 Report
The presented paper is a very good study about active noise control. The paper is correctly written and all the analysis and math are correctly performed. I just have few minor remarks in order to definitely fit the paper for its publication in the chosen journal:
Avoid the use of “we” in scientific paper.
Why chapter discussion is totally missing? Normally a chapter discussion is included to compare proper results with others in literature.
While dealing with Loudspeaker, please mention “Bianco, F., Teti, L., Licitra, G., & Cerchiai, M. (2017). Loudspeaker FEM modelling: Characterisation of critical aspects in acoustic impedance measure through electrical impedance. Applied Acoustics, 124, 20-29.”
Conclusions are a bit short. Please increase them by shortly report what and how the paper analyses, before really reports what were the results of the paper.

Reviewer 2 Report
The subject is interesting and original and the paper well describes the proposed subspace method and its effectiveness. The natural completion of the research would be a verification with measurements on a real application of a spatial ANC; do authors think they can do it and describe in a future work?
Only one clarification about the presentation of the results in figures 7 and 9: is the Energy of the driving signals adimensional?
