Noise Measurement Terminology
This acoustic glossary covers the most essential noise terminology, as well as listing all of the parameters that you may see displayed by the Optimus Sound Level Meters, Trojan Noise Nuisance Recorders and the doseBadge Noise Dosimeter. A brief explanation of each parameter is provided along with additional information where appropriate.
Research has shown that when exposed to noise levels great than 40 dB while sleeping, people are at greater risk of sleep disturbance, which can have an adverse effect on people’s mental well-being. Levels above 55 dB can cause conditions such as high blood pressure and ischaemic heart disease.
Cirrus Research has designed environmental noise monitoring solutions to help businesses across the world protect people and the environment from noise for over 50 years. We’re here to make it easy and simple.
Cirrus Research has developed an integrated cloud-based solution for unattended, remote monitoring of environmental noise, the Quantum Outdoor. We’ve also worked with some of the best environmental instrument suppliers in the world to further enhance Quantum Outdoor with the ability to measure particulates and gases, vibration, weather, and wind speed. So now you can get all the data you need in just one place, anytime, anywhere, and on any device.
Environmental Noise is one of the fastest-growing areas of noise monitoring, mapping, and control. The EU has introduced a number of Directives aimed at increasing the level of information about Environmental Noise across the EU.
In 1996, data from the EU Green Paper on Future Noise Policy estimated that around 20% of the EU’s population, or close to 80 million people, suffer from noise levels that experts consider to be unacceptable. Most of these people become annoyed and suffer from sleep deprivation, which experts fear will lead to adverse health effects.
An additional 170 million citizens are now living in so-called “grey areas” where the noise levels cause serious annoyance during the daytime.
Many of the demands of modern society result in the creation of noise sources, heavy industry, and construction, such as larger airports, additional power stations, and higher road traffic levels.
In addition to this, the expansion of towns and cities, driven by the demand for housing, has often resulted in the development of land near existing noise sources. These trends have meant that many more industries are now required to monitor their environmental noise impact.
But noise pollution can be controlled. Cirrus Research provides a range of solutions to make it easy, simple and less time-consuming.
