Decibel Table: A Comprehensive Guide to Sound Level Measurement

Introduction

Sound is a form of energy that travels through the air in waves. The loudness of a sound is measured in decibels (dB). The decibel scale is logarithmic, meaning that each increase of 10 dB represents a tenfold increase in sound intensity.

The human ear can hear sounds ranging from 0 dB (the threshold of hearing) to 140 dB (the threshold of pain). Sounds below 20 dB are considered quiet, while sounds above 85 dB can be harmful to hearing.

The following table shows the decibel levels of some common sounds:

Stories and What We Learn

Story 1:

Once upon a time, there was a man named John who loved to mow his lawn. He would mow his lawn every Saturday morning, rain or shine. One day, John's neighbor, Mary, asked him to please mow his lawn on a different day because the noise was waking her up. John refused, saying that he had the right to mow his lawn whenever he wanted.

Mary was so upset that she called the police. The police came to John's house and told him that he could not mow his lawn on Sundays because it was a violation of the town's noise ordinance.

John was angry, but he had to obey the law. He started mowing his lawn on Saturdays instead of Sundays. Mary was happy, and she was able to sleep in on Sundays.

What We Learn:

• Noise pollution can be a nuisance and can even lead to conflict.
• It is important to be considerate of your neighbors when making noise.
• There are laws in place to protect people from noise pollution.

Story 2:

Once upon a time, there was a woman named Susan who worked in a noisy office. She would often get headaches and tinnitus from the noise. Susan tried to talk to her boss about the noise, but he told her that there was nothing he could do.

Susan was so desperate that she started wearing earplugs to work. The earplugs helped to reduce the noise, but they also made it difficult for her to hear her colleagues.

One day, Susan's boss saw her wearing earplugs. He asked her why she was wearing them, and she told him about the noise. Her boss was surprised to learn that the noise was bothering her so much.

He promised to look into the matter. A few weeks later, he had the office remodeled to reduce the noise. Susan was so grateful to her boss for taking her concerns seriously. She was able to work more comfortably and her headaches and tinnitus went away.

What We Learn:

• Noise pollution can be a problem in the workplace.
• It is important to talk to your employer about noise pollution if it is bothering you.
• There are things that employers can do to reduce noise pollution in the workplace.

Story 3:

Once upon a time, there was a city that was very noisy. The traffic was loud, the construction was loud, and the people were loud. The noise was so bad that it was difficult to sleep, work, and relax.

The city council decided to do something about the noise pollution. They passed a law that limited the amount of noise that could be made in the city. They also created a noise task force to enforce the law.

The noise task force went around the city and issued fines to people who were making too much noise. The fines were so high that people started to take notice.

Over time, the noise pollution in the city decreased. The traffic was quieter, the construction was quieter, and the people were quieter. The city was a much more pleasant place to live.

What We Learn:

• Noise pollution can be a problem in cities.
• City councils can pass laws to reduce noise pollution.
• Noise task forces can help to enforce noise laws.
