Prepare only the title page, abstract, table of contents and recommendations sections of the report that you are going to submit shortly. ## Short answer Noise levels in industrial towns are 65–80 dB(A) in residential areas and 85–100 dB(A) in factories, exceeding WHO guidelines. About 45% of residents report health issues and 12% of workers show hearing damage, requiring stricter limits, zoning, and protective measures. ## Answer #### Title page ```text REPORT EFFECTS OF NOISE POLLUTION IN THE INDUSTRIAL TOWNS OF NEPAL Submitted to: The Minister Ministry of Forests and Environment Singha Durbar, Kathmandu Submitted by: Prof. Dr. Gopal Prasad Pant Chairman, Noise Pollution Study Committee 1 January 2027 ``` #### Abstract Noise is unwanted and harmful sound. In industrial towns such as Birgunj, Biratnagar, Hetauda, Butwal and Bhaktapur, noise from factories, generators, vehicles, horns and loudspeakers is increasing. The committee measured noise at 120 places in the five towns with sound level meters, interviewed 600 residents and workers, and reviewed hospital records. The measured levels in residential areas were 65 to 80 dB(A) during the day, above the WHO guideline of about 55 dB(A) for outdoor living areas. Factory workers were exposed to 85-100 dB(A) without enough ear protection. About 45 percent of those interviewed complained of headache, sleep loss, irritation or hearing loss, and 12 percent of the workers showed signs of hearing damage. The report concludes that noise is a growing health problem and recommends legal limits, zoning, silencers, ear protection and public awareness. #### Table of contents ```text Abstract ............................................... i 1.

How do residential noise levels compare with the WHO guideline? A. 65 to 80 dB(A) measured, above the guideline of about 55 dB(A) B. Below 40 dB(A) C. Equal to the guideline D. Not measured Answer: A. Residential readings exceeded the WHO guideline of about 55 dB(A). (Key point: Noise levels vs guideline) 2. Which methods did the committee use? A. Measurement at 120 places, interviews with 600 people and hospital records B. Only newspaper review C. Only a satellite survey D. A phone poll of 10 people Answer: A. The abstract lists sound level meters, interviews and hospital records. (Key point: Abstract methods) 3. What does the table of contents list? A. Sections and subsections with page numbers B. Summary of findings C. Names of respondents D. Costs of the study Answer: A. A table of contents shows headings with page numbers, including the front and back matter. (Key point: Table of contents purpose) 4. Which recommendation protects factory workers? A. Ear plugs or muffs, limited hours in noisy places and regular hearing tests B. Plant trees only C. Ban loudspeakers D. Publish data Answer: A. Workers exposed to 85-100 dB(A) need protection and monitoring. (Key point: Protecting workers) ## Related in Communication English - [Final project report: title page, abstract, recommendation](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Afinal-report-title-abstract-recommendation) — Communication English, chapter 8 - [Report on road accidents on highways](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Areport-road-accidents-highways) — Communication English, chapter 9 - [Report on sound pollution in Kathmandu Valley](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Areport-sound-pollution-kathmandu) — Communication English, chapter 9 - [Proposal to start a company: title, abstract, objectives](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Aproposal-company-big-organization) — Communication English, chapter 6 - [Report on environmental pollution in Asia](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Areport-environmental-pollution-asia) — Communication English, chapter 9 - [Report on development of IT in Nepal](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Areport-it-development-nepal-ministry) — Communication English, chapter 9 ## Related in other subjects - [Contents of site investigation report](https://www.bctengineer.com/question.md?key=semester_5%2Ffoundation_engineering%3Asite-investigation-report) — Foundation Engineering, chapter 2, asked 5× - [Contents of project appraisal report](https://www.bctengineer.com/question.md?key=semester_7%2Fproject_engineering%3Aappraisal-report-contents) — Project Engineering, chapter 2 - [DSM techniques implemented by Nepal Government](https://www.bctengineer.com/question.md?key=semester_7%2Futilization_of_electrical_energy%3Adsm-techniques-nepal-government) — Utilization of Electrical Energy, chapter 6 - [How Nepal Government takes norms and rates](https://www.bctengineer.com/question.md?key=semester_7%2Festimating_and_costing%3Anepal-govt-norms-rates) — Estimating and Costing, chapter 4
