Noise pollution is a growing concern in many cities around the world. It can cause a lot of health problems, including hearing loss, insomnia, and stress. Therefore, it is essential to know how loud certain noises are, so that we can take appropriate measures to reduce our exposure. In this article, we will look at how loud 70 dB is, and what activities produce that level of noise.
What is 70 dB?
Decibels (dB) is a unit of measurement used to quantify the intensity of sound. A sound that is 70 dB loud is considered to be moderately loud. For comparison, a normal conversation is about 60 dB, while a vacuum cleaner produces 75 dB. Therefore, 70 dB falls somewhere in between a conversation and a vacuum cleaner in terms of loudness.Noises that produce 70 dB
There are many daily activities that produce 70 dB of noise. Some of these include:- A television or radio at a normal volume.- A hair dryer or blender.- Traffic noise from a busy street.- A lawnmower or chainsaw.- A crowded restaurant or bar.It is important to note that exposure to 70 dB of noise for an extended period can still cause health problems, especially if the exposure is frequent.Effects of 70 dB on health
Exposure to 70 dB of noise for an extended period can cause hearing loss, tinnitus, and high blood pressure. It can also cause sleep disturbances and fatigue, which can lead to a decrease in job performance and cognitive abilities. Chronic exposure to noise pollution has also been linked to cardiovascular disease, anxiety, and depression.Preventing exposure to 70 dB
The best way to prevent exposure to 70 dB is by reducing exposure to loud noises whenever possible. This can be achieved by:- Wearing earplugs or noise-cancelling headphones in noisy environments.- Turning down the volume on electronic devices.- Using quieter machines or appliances whenever possible.- Avoiding loud environments such as concerts and clubs.Overall, noise pollution is a serious issue that affects not only our hearing but our overall health and well-being. Therefore, it is essential to take steps to reduce exposure to loud noises and protect ourselves from the harmful effects of noise pollution.
