Some sources are continuous while others can be less frequent. Community noise is usually a combination of different sources like car traffic, construction sites, playgrounds, etc. In other cases, community noise can be measured for settling disputes between neighbors.Ĭommunity noise is more difficult to define and measure because several sources of noise can affect measurements. The main reason for measuring noise levels in residential or urban environments is to keep the general population safe from exposure to dangerous noise levels. Sound level meters are often used for measuring community or environmental noise. Here are a few examples of sound level meter functions: Community Noise Analysis They have the general purpose of measuring noise, but their main role depends on what environment they are used in. Sound level meters are used in several types of scenarios where measurement and monitoring of noise levels are necessary. Or, to measure sound pressure levels when calibrating audio equipment. For instance, you can use a sound level meter in your home or workplace to avoid exposure to dangerous noise levels.
Sound level meters can also be used in other environments such as for setting up audio equipment at concerts or for personal reasons. This includes workers, city dwellers, and the general population. This way, they protect the people who are exposed to high levels of noise. Sound level meters are typically used by regulatory authorities and workplace safety specialists to make sure noise levels are kept under recommended reference levels. They are also used in urban environments to monitor noise levels from car, rail, and air traffic, public events, and other sources of sound. They are utilized in multiple scenarios in factories and other industrial plants and on construction sites.
Sound level meters are useful for measuring, monitoring, and controlling noise levels.
They are typically used by safety professionals to monitor conditions and the observance of recommended exposure limits (RELs). However, in certain cases, sound level meters used for continuous monitoring of noise levels in a particular environment can be permanently installed.ĭecibel meters are used for measuring environmental, industrial, or machine noise levels.
#SOUND DECIBEL METER PORTABLE#
Some decibel meters also show additional acoustic parameters such as the equivalent continuous sound level (Leq).ĭecibel meters are usually portable and run on batteries. These measured noise levels are expressed in decibels (dB) and displayed on the instrument’s screen. The decibel meter then uses signal processing to apply frequency and time weightings to the signal according to international standards.Ī decibel meter responds to sound much like a human ear to give objective acoustic measurements of noise levels in a certain environment. The mic captures sound pressure deviations and converts them into an electrical signal that is made stronger by a preamplifier. Other common names include noise meter and sound level meter.Ī decibel meter uses a microphone to capture sound. For this reason, the decibel meter is also known as a sound pressure level (SPL) meter. What Is a Decibel Meter?Ī decibel meter is a sound pressure measuring instrument for standardized measurements that uses the decibel scale.
#SOUND DECIBEL METER HOW TO#
In this article, we’re going to shed light on what a decibel meter is and how to properly use it. This sound measurement instrument is gaining popularity and has many people asking what it’s for and how to use a sound level meter. Have you ever wondered what a sound level meter is? You are not alone.
