This risk level is considered to be normal-but just because it is normal doesn’t mean it can’t have negative impacts! It is equivalent to sounds that are easily noticeable and may compete with what you are trying to listen to and focus on, such as rain muffling, a conversation, or noise in a quiet office. In general, the children in this study found it harder to focus because of the constant exposure to noise. Children exposed to higher levels of noise had lower test scores. A study performed in 2008 found that noise led to primary school children developing a lack of motivation and reduced memory and reading comprehension. Chronic exposure to sound levels above this range can also lead to impaired cognitive function, especially in children. This range is associated with a lack of sleep, and prolonged exposure may also cause headaches and irritability. It is equivalent to sounds that are noticeable and can become disruptive depending on the environment-the humming of a fridge, a running stream, or other background noises. This range is not associated with any specific health problems-but, anything exceeding this sound level can cause damage to your sleep patterns. It may also be difficult to hear at this level if you have hearing loss. ![]() It is equivalent to sounds that are audible, but still quiet-think of soft whispering (3 feet away), rustling leaves, and mosquitos buzzing. This range is not associated with any negative health effects, and is actually correlated with times of relaxation and good sleep. It may be difficult to hear at this level if you experience hearing loss. It is equivalent to sounds that are not very audible, including a ticking watch or normal breathing. Below is a list of different sound level ranges, what they sound like, and how they can affect your health. Although noise is an unwanted sound, people can (or have to) become accustomed to it because they can’t control it-we often normalize noise to make life more bearable. Noise is an unwanted sound-a noise that makes you annoyed, stressed, distracted, or mad. Sound refers to what we’re hearing, while noise is more about how a sound makes us feel. It is important to remember that sound and noise are two different things. But, what do these sound levels actually mean for you and your health? If a sound level increases by 10 on the decibel scale, that means the sound is ten times more intense. ![]() Decibels are calculated using sound meters, like the one used in the “Map the Sound” button on the Noise Project app. Sound levels are measured in decibels, which can range from 0 to over 120. These different ways relate to different ranges of sound levels. Noise pollution can manifest itself in many ways like talking, transportation, or construction.
