The Song Dynasty Shipwreck Monitoring and Analysis Using Acoustic Emission Technique
Round 1
Reviewer 1 Report
Comments:
1. Acoustic Emission Testing (AET) is a nondestructive testing method that is based on the generation of waves produced by a sudden redistribution of stress in a material. Not only RH difference but also, human factors will lead to a ringing counting. From Figure 12, it generally happened that ring counting(>0) shows a pattern similar to China Festival Pattern without normal distribution. This leads to my doubt about whether the ringing counting is due to climate-induced damage or just activity from visitors during peak season period, since the wooden ship is placed in a public environment. To reply to my doubt, the authors should provide support materials: 1) prove that human activity is not confounding the results, or disentangle respective wave types 2) analysis what causes the variation of RH and DFRH within one year in an indoor environment (might be due to the local weather, population, etc).
2. Equation (1), the high R-Square number does not mean much, since it is post-fitting(choose regression model after seeing the data). My suggestion is to conduct analysis to support the exponential relationship.
3. Other - lacks the definition of DFRH; lacks detailed explanation of AE in the MM section; lacks axis labels in Figure 9.

Reviewer 2 Report
As I noted in the tick box, the abstract adequately describes what is in the paper. It is about the use of acoustic emission monitoring as an indicator of damage occurring to support indoor climate management. The case is of a wooden shipwreck, but it is relevant to conservation of other wooden cultural heritage objects vulnerable to stresses from humidity cycling - such as furniture, artworks and buildings. Some practical aspects are covered, including the avoidance of damage caused by the installation of the equipment. The state of the art is adequately described.
The paper needs some minor editing to correct the English and a few typing errors, but the text is otherwise clear and understandable. The research should be of interest to the wooden cultural heritage conservation community - particularly preserved shipwrecks. The state of the art is adequately described and it fits into the topic of this special issue. The application is original (note information below)
As indicated by the tick boxes on the review form, the conclusions are consistent with the evidence and arguments presented add address the main question posed.
Note for information - AE was installed on the Mary Rose wreck in the UK, but the data was not yet analysed or published - partly because of not knowing what to do to interpret the data. They are no longer on the ship. https://hanwell.com/case-study/mary-rose-museum/
The paper needs only correction of the English before publication. These edits are minor.

Response 1: We are also paying attention to the research progress of the Mary Rose wreck.
As you said, there have been no reports of acoustic emission so far. We have made modest correction of the English in this paper.
