Round 1

Reviewer 1 Report

The study aims to present the “GIS Mapping of Short-term Noisy Event of Diwali Night in Lucknow City.” The paper is well organized, but there are some major comments to address before being published. Then, I would like to suggest a major revision.

1. The abstract is too long. Advice to reduce it
2. The introduction is week. Better to combine the introduction and literature review. Make a more strong introduction. Better to review more high quality past research papers
3. Figure 1 is very simple. You do not need to add it. Just explain it
4. Advice to add a study area map.
5. Citations are missing in the whole manuscript. Need proper citations
6. Better to follow the journal format. No need to add the “objective” section. It can be included in the last paragraph of the introduction
7. Figures are not clear.
8. Some equations are in the “result and discussion” need to move to methodology. The methodology section is week.
9. What is the limitation of the study?
10. How the applicability of the methodology in similar study areas.
11. Reference materials are very weak. Need more reading

Reviewer 2 Report

The article "GIS Mapping of Short-term Noisy Event of Diwali Night in Lucknow City" is very interesting, showing a study based on the noise data acquired both directly, with smartphones used similarly to Sound Level Meters after a calibration process, and indirectly, with the analysis of the increase of air pollutants (PM2.5, PM10, SO2, NO2, O3), during bursting of firecrackers on Diwali night in Lucknow City. The data were spazialized in a Gis environment and the research was integrated by the effects of these short terms noisy events on residents’ health.

Some additional remarks:

• The overall paper should be reorganized and written more comprehensively, integrated with changes in the shape
• The “Introduction” paragraph should be integrated by the “Research gap” and “Objectives” paragraphs.
• The entire text should be more precise, with the elimination of all the “etc.” and, also, in the explication of concepts.
• All the “Literature review” paragraph could be reduced or integrated by further bibliographic references.
• Sometimes there is the reference to elements which are never been defined.
• In addition, all the paper is characterized by a poor bibliography, that must be implemented by further references also related, for example, to the smartphone noise application and the IITR Lucknow data. Moreover, references in the text should be better explained, because it is not very clear the right reference for some sentences.
• Figures and Tables are not referenced in the text appropriately and their captions contain their explication. It would be better to reduce the caption and move and discuss their explanation in the text. Moreover, it is highlighted the repetition of images or part of them. In addition, it would be interesting to show also a spatial framework of the case study.
• Sometimes, in the text, there is the reference to formulas which are not reported. It is suggested to make the appropriate changes.
• It is suggested to pay attention to grammatical and punctuation errors and the repetition of the same words.
• It is suggested to highlight the differences between the noise models and the interpolation technique, and the data acquired in crowdsourcing ad the ones acquired with the traditional methods. Some information should be find in: “Graziuso G, Mancini S, Francavilla AB, Grimaldi M, Guarnaccia C. Geo-Crowdsourced Sound Level Data in Support of the Community Facilities Planning. A Methodological Proposal. Sustainability. 2021; 13(10):5486”. https://doi.org/10.3390/su13105486  and   Picaut, J.; Fortin, N.; Bocher, E.; Petit, G.; Aumond, P.; Guillaume, G. An Open-Science Crowdsourcing Approach for Producing Community Noise Maps Using Smartphones. Build. Environ. 2019, 148, 20–33”.
• The “Methodology” and the “Result ad discussion” paragraphs need a further reorganization and the integration with further explanations. Also the images and the tables in the six paragraph must be discussed more precisely

The overall paper has been reorganized and written more comprehensively as per the suggestion of the reviewer

• The “Introduction” paragraph should be integrated by the “Research gap” and “Objectives” paragraphs.

The paragraphs have been combined

The entire text should be more precise, with the elimination of all the “etc.” and, also, in the explication of concepts.

The concepts have now been expressed in more detail than before

All the “Literature review” paragraph could be reduced or integrated by further bibliographic references.

The paragraphs have been reduced and more references have been added in the article

• Sometimes there is the reference to elements which are never been defined.

Such elements have been attempted to be eliminated from the manuscript

• In addition, all the paper is characterized by a poor bibliography, that must be implemented by further references also related, for example, to the smartphone noise application and the IITR Lucknow data. Moreover, references in the text should be better explained, because it is not very clear the right reference for some sentences.

The references have been increased substantially now and the authors hope that the reviewer finds the bibliography satisfactory now

• Figures and Tables are not referenced in the text appropriately and their captions contain their explication. It would be better to reduce the caption and move and discuss their explanation in the text. Moreover, it is highlighted the repetition of images or part of them. In addition, it would be interesting to show also a spatial framework of the case study.

The captions of the figure have been revised and more informative figures have been added in the manuscript

• Sometimes, in the text, there is the reference to formulas which are not reported. It is suggested to make the appropriate changes.

The appropriate changes have been made

• It is suggested to pay attention to grammatical and punctuation errors and the repetition of the same words.

The grammar and punctuations errors have been heavily rectified in the article

• It is suggested to highlight the differences between the noise models and the interpolation technique, and the data acquired in crowdsourcing ad the ones acquired with the traditional methods. Some information should be find in: “Graziuso G, Mancini S, Francavilla AB, Grimaldi M, Guarnaccia C. Geo-Crowdsourced Sound Level Data in Support of the Community Facilities Planning.

The authors studied the reference and have now added it in the article

• The “Methodology” and the “Result ad discussion” paragraphs need a further reorganization and the integration with further explanations. Also the images and the tables in the six paragraph must be discussed more precisely

The “methodology” and “results and discussions” have been further reorganized and the images have been discussed more precisely.

 

Reviewer 3 Report

The submitted document deal with a very interesting topic but is very confusing. The message at present that the paper is passing is that it looks like the document is reflecting a confused state of the authors about noise field, which I do not think they have. Thus, I seriously ask the authors to consider re-edit the paper according to the suggestions, because at present the document cannot be considered for publication.

 

ArcGIS is a commercial software I would avoid to mention. Please only refer to a GIS.

Chapter 3 is weird and can be removed. Those aspects should be simply reported in the introduction.

Same for chapter 4. Those 2 chapters should be correctly moved into the introduction or methodology.

All chapter 2, however, seems useless. I would suggest the authors to remove it, instead of trying to correct all the possible errors in it.

Different noise model can estimate noise in different ways (Ascari, E., Licitra, G., Teti, L., & Cerchiai, M. (2015). Low frequency noise impact from road traffic according to different noise prediction methods. Science of the Total Environment, 505, 658-669.)

I really suggest the authors to put more emphasis in showing some novelties in the work, as well as trying to show its importance and the importance of the argument.

Introduction should be improved: the first improvement needed regard the noise and health effect part, which is really lacking. I suggest the authors to improve with some detailed effects and references like: “Exposure to noise is associated to sleep disorders with awakenings (Muzet A. Environmental noise, sleep and health. Sleep Med Rev 2007; 11: 135–42), learning impairment (Zacarías, F. F., Molina, R. H., Ancela, J. L. C., López, S. L., & Ojembarrena, A. A. (2013). Noise exposure in preterm infants treated with respiratory support using neonatal helmets. Acta Acustica united with Acustica, 99(4), 590-597; Minichilli, Fabrizio, et al. "Annoyance judgment and measurements of environmental noise: A focus on Italian secondary schools." International journal of environmental research and public health 15.2 (2018): 208; Erickson, Lucy C., and Rochelle S. Newman. "Influences of background noise on infants and children." Current Directions in Psychological Science 26.5 (2017): 451-457.), hypertension ischemic heart disease (Dratva, J., et al. (2012). “Transportation noise and blood pressure in a population‐based sample of adults.” Environmental Health Perspectives, 120(1): 50–55. Babisch, W., Beule, B., Schust, M., Kersten, N., Ising, H., ‘Traffic noise and risk of myocardial infarction’, Epidemiology, 16, 2005, pp. 33–40. ), diastolic blood pressure (Petri, D., Licitra, G., Vigotti, M. A. & Fredianelli, L. (2021). Effects of Exposure to Road, Railway, Airport and Recreational Noise on Blood Pressure and Hypertension. Int. J. Environ. Res. Public Health 2021, 18(17), 9145), reduction of working performance (Vukić, L., Fredianelli, L., & Plazibat, V. (2021). Seafarers’ Perception and Attitudes towards Noise Emission on Board Ships. International Journal of Environmental Research and Public Health, 18(12), 6671. Rossi, L., Prato, A., Lesina, L., & Schiavi, A. (2018). Effects of low-frequency noise on human cognitive performances in laboratory. Building Acoustics, 25(1), 17-33.), annoyance (Miedema HME, Oudshoorn CGM. Annoyance from transportation noise: relationships with exposure metrics DNL and DENL and their confidence intervals. Environ Health Perspect 2001; 109: 409–16.

 

Honestly, I failed to understand what the authors mean with noise data needed for the noise maps. When a noise map is produced, depending on the type of noise source you are mapping, different information are needed. For example, for road traffic noise, traffic flows, speed, traffic composition, type of asphalts are all information needed to the noise model in order to simulate noise in the area. Noise measurements are then needed to validate the simulation, and this is a really important aspect to always perform.

In this case, in the introduction you can add a period dealing with road traffic noise. Such as: traffic noise, is the most impacting noise source affecting human modern life style (Ruiz-Padillo, Alejandro, et al. "Selection of suitable alternatives to reduce the environmental impact of road traffic noise using a fuzzy multi-criteria decision model." Environmental Impact Assessment Review 61 (2016): 8-18;.) and the parameters affecting its emission are many (Sandberg U, Ejsmont J. Tyre/Road Noise Reference Book. Kisa, Sweden: INFORMEX; 2002), but beside the engines and the flow composition, the acoustic impedance (Bianco, Francesco, et al. "Stabilization of a pu sensor mounted on a vehicle for measuring the acoustic impedance of road surfaces." Sensors 20.5 (2020): 1239. Praticò, Filippo G., Rosario Fedele, and Gianfranco Pellicano. "Monitoring Road Acoustic and Mechanical Performance." European Workshop on Structural Health Monitoring. Springer, Cham, 2020.),  tyre model (Licitra, G., Teti, L., Cerchiai, M., & Bianco, F. (2017). The influence of tyres on the use of the CPX method for evaluating the effectiveness of a noise mitigation action based on low-noise road surfaces. Transportation Research Part D: Transport and Environment, 55, 217-226.), pavement ageing (Teti, Luca, et al. "Modelling the acoustic performance of newly laid low-noise pavements." Construction and Building Materials 247 (2020): 118509.), pavement texture (Del Pizzo, Alessandro, et al. "Influence of texture on tyre road noise spectra in rubberized pavements." Applied Acoustics 159 (2020): 107080; Praticò, Filippo Giammaria. "On the dependence of acoustic performance on pavement characteristics." Transportation Research Part D: Transport and Environment 29 (2014): 79-87.), mixture (Praticò, Filippo G., and Fabienne Anfosso-Lédée. "Trends and issues in mitigating traffic noise through quiet pavements." Procedia-Social and Behavioral Sciences 53 (2012): 203-212; de León, Gonzalo, et al. "Evaluation of tyre/road noise and texture interaction on rubberised and conventional pavements using CPX and profiling measurements." Road Materials and Pavement Design 21.sup1 (2020): S91-S102.) are the most important.

 

 

Result session is really something new. This sentence, however, should not be meant as a positive aspect. I mean, it is not really a noise map, but it something else the authors should really explain in their work. This means to compare it with a real noise map and a better description of it, its utility and so on. What is the height above the ground where the maps are taken?

6.3: what is doing air monitoring here? The paper is dealing with noise and it wasn’t introduced before. I thing that it should be removed and focues on noise only, or the part before and the title should be fixed accordingly.

Finally, studying a particular state of an area (festival, and so on) can be significant if evaluated with respect to the ordinary situation, which means to compare the results of your map as a differential value to the normal acoustic map.

The chapter 3 has been removed and assimilated by the introduction now

Same for chapter 4. Those 2 chapters should be correctly moved into the introduction or methodology.

The chapter 4 has also been integrated into the introduction

All chapter 2, however, seems useless. I would suggest the authors to remove it, instead of trying to correct all the possible errors in it.

Most of the content from chapter 2 has now been removed from the manuscript

6.3: what is doing air monitoring here? The paper is dealing with noise and it wasn’t introduced before. I thing that it should be removed and focues on noise only, or the part before and the title should be fixed accordingly.

The characterization of short term noise event is done using the air quality monitoring data. It is very difficult to monitor short-term noise events using noise data, to overcome this limitation, the collection of available air quality is done. This is a reason the authors believe that this section should remain in the manuscript.

Finally, studying a particular state of an area (festival, and so on) can be significant if evaluated with respect to the ordinary situation, which means to compare the results of your map as a differential value to the normal acoustic map.

The authors have added maps to compare the data obtained on days without the festival.

The authors would like to thank the reviewer for accepting their article. 

Reviewer 2 Report

The paper is more readable after the authors’ changes.

However, other minor revisions are requested.

Specifically, is “Scheme 1” a Figure? Why did you not define it as a figure and recall it in the text? Moreover, it is not properly appropriate, because the caption describes “Mapping on the Diwali Night” and the scheme represents the world. It would be better to replace it with another figure more representative of the application of the methodology to the case study, and move it the “Methodology” paragraph.

The introduction should be divided into two parts: the first part can focus on the goal of the paper and the second part can be organized on the description and the state of the art of noise modelling.

The captions of figures and table can be just named only with a simple title, while their explanation can be integrated in the text of the paper.

The Scheme 1 has now been modified and has been used as the Graphical Abstract that will give the reader a basic idea about the focal point of this paper. Upon considering the comments of all the reviewers, the authors took this decision. The authors are hopeful that the new placing of Scheme 1 (with modifications) will look more suitable.

The introduction should be divided into two parts: the first part can focus on the goal of the paper and the second part can be organized on the description and the state of the art of noise modelling.

As per the reviewer’s comment, the introduction has been divided into two parts.

The captions of figures and table can be just named only with a simple title, while their explanation can be integrated in the text of the paper.

The authors have made the required changes in the new version.

 

Reviewer 3 Report

Please remove pictures from the introduction. Consider it as a "graphical abstract". 

Correct information have been added to the intro, and the contents are perfect now. The contents are really more clear. However, the intro is now too long and it should be divided into 2 chapter: a proper intro, with the background part and just a slight description about what the paper will do. A second methodology chapter should report the part of methodology.

The comparison maps are really useful now.

Please, add more description of how the standard noise maps have been computed.

The authors thank the reviewer for this comment and would like to mention that the introduction has been curtailed.

The comparison maps are really useful now.

Please, add more description of how the standard noise maps have been computed.

In case of noise mapping, we primarily are required to incorporate the terrain data and noise data. The noise data of different sources are integrated and then terrain and noise data is incorporated in noise propagation model to predict the level of noise at the desired location. By developing a noise propagation model, we can make noise predictions for even those locations where we do not have any noise data. The predictions can be displayed as a noise map. In this case, the same approach has been used.

During the short term noise event like Diwali, it is difficult to collect noise data. So, the authors have tried to collect noise data indirectly using air quality. During the Diwali night, noise levels increases and pollutants in the air increases, and the correlation is same. Using the same air pollutants level, we can easily get the noise level data. Since this has never been tried, this is the novelty of the paper as we will be able to make predictions related to noise in short term noise events like Diwali. The authors have also added the same explanation in the introduction section too.  

Reviewer 4 Report

The paper has significantly improved. Perhaps, now it is even too much. Whit this, i mean that some of the section are now too long and should be divided properly (introduction).

Avoid pictures in the introduction, but also keep them as they are useful. Perhaps, move them to another specific chapter.
Please better specify how noise maps have been performed, how they connect with other methodology already in literature.

I do not understand how the part of air pollution relates to the noise map, so please explain it better.
