Decibel Dilemma
Notes:
- Easy for people to encounter sound levels that cause health effects.
- A lot of places are polluted with noise.
- We are all exposed to sounds everywhere at school, our homes, the street etc.
- Difficult to escape sound completely.
- 120 million people worldwide are experiencing hearing difficulty.
- Booming population and loss of rural land may be some of the causes of noise pollution.
- There is a lack of noise regulation in many parts of the world.
- Some experts define noise as "unwanted sound" but some people need sound to concentrate.
- Sound intensity is measured in db decibels.
- zero dBA is used to measure the point at which a person begins to hear sound.
- dBA is used to indicate how humans hear a given sound.
- A sound that exceeds 85 dBA is considered a hazardous noise level.
- That is equivalent to a typical 8 hour work day.
- "Sound exposure level" accounts for variations in sound from moment to moment.
- "Equivalent sound level" determines the value of a steady sound with the same dBA sound energy as that contained in a time varying sound.
- Industries that require work with high levels of noise exposure include agriculture, mining, manufacturing, utilities, transportation and the military.
- There needs to be protection against noise pollution for workers.
- Noise has affected the quality of life for many people.
- Secondhand noise is noise that is affecting people that are not producing it, such as living near an airport.
- The country side is not immune to noise pollution.
- 75% of farm workers have hearing problems.
- Noise pollution has affected other parts of the body such as not being able to sleep and increased heart rate.
- Noise pollution can cause tinnitus, ringing in the ear and hearing loss
Summary: You may probably have heard of pollution and the different types of pollution that are out there in the world, right? But have you ever heard of a pollution that involves noise? Well that's something you don't hear everyday, but it is occurring as your reading! It is easy to encounter high levels that cause health effects, like deafness, tinnitus, or ringing in ear. About 120 million people have hearing problems worldwide from noise pollution. "Many jobs cause noise pollution that affect the workers in serious ways. Even farmers and people living in rural areas cannot avoid noise pollution." About 75% of the farmers have hearing problems. Noise pollution also contributes to loss of sleep and increases heart rate. Noise has affected the quality of life for many people. However, we can't escape from it or prevent it because it's like second nature to most of us. The EPA has set regulations for noise pollution levels, but it is a problem that is difficult to solve.
Reflection: While reading this article I have never thought of noise being a pollution towards us, since it has been around for quite a while now. But now that I think about it, maybe having to much noise can be a problem. From causing cancer to deafness. We should try to make less noise instead of creating more. However, it is difficult since it is naturally made.
