Introducing The All New Sound Meter

A sound meter, also often referred to as a noise level monitor is a small, portable device that measures sound pressure levels directly and incorporates frequency weighting networks that roughly represent the inverse of equal loudness contours at different levels. A standard meter is made consisting of electronic circuitry that operates on the electrical signal produced by the sound being picked up by the microphone and converted into an electrical signal, allowing the necessary properties to be measured.

As we go forward in the article, we’ll discuss more about the noise level monitor, its machinery of it, and others.

The Sound Meter Simplified

In 1960, the first handheld transistorized sound level meter was made available to the public. Accurate, adaptable, portable noise-measuring tools were created later in the early 1970s as concern about noise pollution grew. Since loudness is a personal preference and is dependent on the listener’s ear characteristics, sound level is not a reliable indicator of loudness. Scales have been created to link loudness with precise sound measurements to solve this issue.

Sound Meter

As already described at the very outset of the blog that a sound meter is a device that simply ‘measures the volume and loudness of music, noise, and other noises.’ By switching between a scale that reads sound intensities evenly for most frequencies, known as an unweighted scale, and a scale that incorporates a frequency-dependent weighting factor, a conventional sound-level meter may provide a response that is more like that of the human ear.

Functions And Common Usage of A Noise Level Monitor

There are many different applications for a noise level monitor, many of which include the need to measure or keep track of ambient noise levels. For example, it is used for noise analysis within communities.

  • Noise in the community or the environment may be measured with a sound level meter. When neighbors have a disagreement, a noise meter might help sort things out.
  • The definition and measurement of community noise are more complicated because of the multiplicity of noise sources that might influence such efforts. The frequency of some sources is more consistent than others.
  • In most cases, local governments implement separate sets of rules for commercial, residential, and construction settings. These rules typically change during the day.
  • Community noise may be measured most precisely using daytime and nighttime readings taken at different times. In order to get an accurate reading of the average and maximum peak of noise, they should be conducted over a longer time frame.

To choose the right sound meter for you, the first step in measuring noise is figuring out what exactly needs to be measured. Class 1 is more precise than Class 2, but it also costs more. Octave band analysis and the octave band may be two further optional extras to think about. The NC curve may be exported for noise source diagnosis using the octave band and octave band analysis features. Finally, if signal analysis is required, time history recording is a necessary component.
