A Many-Objective Joint Parallel Simulation Method for Acoustic Optimization Design of Sound-Absorbing Structures
Round 1
Reviewer 1 Report
The paper “A High-dimensional Multi-objective Joint Parallel Simulation Method for Acoustic Optimization Design of Sound-absorbing Structures” creates a high-dimensional multi-objective MATLAB with COMSOL joint parallel simulation optimization method based on the NSGA III algorithm framework, for acoustic optimization design of sound-absorbing structures, and uses this scheme to construct a parallel low-frequency broadband high sound-absorbing structure.
After analyzing the paper, there are some observations:
- In Figure 3, is it not specified what PML represents? there is also no justification for why this model is used.
- bibliographic references regarding the equations used are missing;
- after equation (9) it must be presented how to determine R - reflection coefficient - including the bibliographic reference;
- the equations defining the vibrational velocity from Figure 12 are missing;
- the idea of optimization is interesting but regarding the results obtained of the sound absorption coefficient from figures 7, 9, 11 no correlations are presented with other similar results from the literature or experimental tests to validate the results.
- In the chapter on conclusions, it should be made clearer what are the notable results obtained from this study and its usefulness.
The paper may be published after some additions.

Reviewer 2 Report
The manuscript entitled “A High-dimensional Multi-objective Joint Parallel Simulation Method for Acoustic Optimization Design of Sound-absorbing Structures" explores the combined use MATLAB and COMSOL in running a parallel simulation to optimise sound absorber designs. The study is interesting and contributes to the widening knowledge in the field of sound absorber designs. However, the paper requires revisions along the following lines to justify publication.
1. The paper needs thorough proofreading to iron out persistent grammar and sentence structuring errors.
2. The title can be simplified, it is not clear why ‘high-dimensional’ is used. The title may simply read “A Multi-objective Parallel Simulation for Acoustic Optimization of Sound-absorbing Structures”. However, I leave it to the authors to assess the suitability.
3. Check the formatting of equation (12).
4. The post-processing steps used to compute sound absorption from the simulation data is insufficiently reported.
5. Did the authors carry out a mesh sensitivity analysis?
6. It is unclear how the frequency-dependent mesh is modelled.
7. How did the authors model the sound source?
8. It is unclear how the frequency dependency is modelled.
9. Please present an image of the meshed model and discuss the size of the model, i.e., nodes and elements.
10. The introduction section needs improvement. Papers on acoustic simulation not reviewed. Some examples are below.

11. Can the authors expand the discussion by contrasting the proposed construct in comparison to others in the literature?
12. Did the authors receive any counterintuitive data? Please include this if any.
13. What are the limitation and future aspects of this study?
14. Please include all details regarding experimental tests. How many samples (n) of each configuration were analysed.

Reviewer 3 Report
The references for some equations are missing....boundary conditions, wave equation...
There is no comparison of results with measurements...or some empirical equations...
