Road traffic noise is the dominant source affecting human exposure above the EU's threshold of 55 decibels (dB) for daily exposure and 50 dB for night exposure. Around 100 million people are exposed to road traffic noise above 55 dB in the 33 member countries of the EEA (Figure 1).

A Study of Decibels. Normal conversation is about 60 decibels (dB), a lawnmower is about 90 dB, and a loud rock concert is about 120 dB. Sounds louder than 85 dB pose a risk of permanent hearing loss, depending on how long and how often you are exposed to them. Additionally, studies show that anything at or above 65 dB can trigger an increase ...

However, construction site noise is not only loud but can also be hazardous to one's hearing. According to the CDC, 14% of all construction workers have considerable hearing difficulty because of job-related noise. The National Institute for Occupational Safety and Health (NIOSH) sets a boundary of 85 decibels (dBA)—the units used to ...

Additionally, studies show that anything at or above 65 dB can trigger an increase in blood pressure, heart rate, and stress hormones in the blood. Trucks and motorcycles can emit noise in the range of 90–96 dB, comparable to the sound a subway train makes from 200 feet away, while average heavy traffic is more like 80 dB.

Introduction. Noise, or unwanted sound, is one of the most common environmental exposures in the United States (García 2001).In 1981, the U.S. Environmental Protection Agency (EPA) estimated that nearly 100 million people in the United States (about 50% of the population) had annual exposures to traffic noise that were high enough to be harmful to health (Simpson and Bruce 1981).

Simply defined, noise pollution is any unwanted sound or any sound that interferes with hearing, causes stress, or disrupts our lives. Sound is measured either in dynes, watts, or decibels. Note that decibels (db) are logarithmic; that is, a 10 db increase represents a doubling of sound energy.

For example, 90 decibels is four times as loud as 70 decibels and 110 decibels — the noise level that just one Harley may approach — is about 16 times as loud.

Noise reduction ratings are measured in decibels (dB). Most hearing protection devices have ratings that range from 0 dB to 35 dB. A noise reduction rating is a "best case" rating measured in a laboratory; the actual sound reduction provided by the protector may be much less.

The World Health Organization (WHO) defines noise above 65 decibels (dB) as noise pollution. To be precise, noise becomes harmful when it exceeds 75 decibels (dB) and is painful above 120 dB. As a consequence, it is recommended noise levels be kept below 65 dB during the day and indicates that restful sleep is impossible with nighttime ambient ...

Noise pollution is considered to be any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sound is measured in decibel s. There are many sounds in the environment, from rustling leaves (20 to 30 decibels) to a thunderclap (120 decibels) to the wail of a siren (120 to 140 decibels).
