Title: Modulation of the Acoustic Vibration Performance of Wood By Introducing the Periodic Annular Groove Structure

Author: Zhang, et al.

 General

This paper describes the changes in the dynamic properties due to a change in the construction of the specimen. The relationships between the dynamic properties, in this case the natural frequencies, and the construction (cross-section) are well known. From this point of view, the paper is only a specific example of the calculation of natural frequencies and the specific parameters derived from them. However, from the point of view of a user who is not familiar with the relationships, the article may be of usable value.

The design of the article and the experiment is good.

Specific

Describe other possible forms of structural modification (notches,...). Describe also how the change of surface affects the reflection of sound.

L101 – add the Latin name for Paulownia wood

L143, 145 – use “tangential” instead of “chordal”

L154 – “first-order free vibration nodes.” – did you mean at nodal points of the first vibrational mode? – If yes, correct this

L158 – “number of solution orders” – number of vibrational modes

L159 – “bending vibration intrinsic frequency f.” – what did you mean with this? Bending vibration natural frequency?

L172 – intrinsic -> natural

L259 – “first-order bending” – first vibrational mode

Reviewer 2 Report

Comments and Suggestions for Authors

I have carefully reviewed your manuscript titled "Modulation of the Acoustic Vibration Performance of Wood By Introducing the Periodic Annular Groove Structure" and find the study to be well-conducted and valuable for publication in the Forests Journal. The investigation of the relationships between structural parameters and acoustic vibration parameters using Finite Element Method (FEM) provides valuable insights into the acoustic properties of wood.

Before accepting the manuscript for publication, I would like to make the following comments for your consideration:

Introduction Enhancement:

In the introduction, elaborate on the importance of Paulownia wood in traditional Chinese musical instruments. Specify the most significant instruments that commonly use Paulownia wood. This additional information will provide context and enhance the relevance of your study.

Scientific Name of Wood Species:

Please ensure to include the scientific name of the wood species (Paulownia) used in the study.

Subtitles Clarity:

On page 8, line 258, and similarly for other subtitles, consider rephrasing to enhance clarity for readers. For instance, "change in f," you might choose another subtitle.

Discussion on Ultimate Use in Musical Instruments:

In the discussion section, please address the final effects of the periodic annular groove structure on the acoustic properties of Paulownia wood and its implications for the ultimate use of this wood in musical instruments. Reference the provided sources (https://doi.org/10.15376/biores.6.3.2632-2646 and https://doi.org/10.15376/biores.14.2.2919-2930) to strengthen the discussion. Clearly articulate how the findings contribute to improving the scientific understanding of wood properties in the context of musical instrument construction.

Comments on the Quality of English Language

I've observed that the authors adeptly employed precise and scientifically English language in their writing.
