![]() ![]() ![]() The decibel (dB) allows us to compare the relative difference in intensity between two values.It establishes a reference point by setting the threshold of human perception as the standard pressure in the air.The decibel (dB) is utilised as a measurement unit for sound pressure levels.Here are few reasons we use Decibel (dB): It is comparable to the soft sound of whispering.īelow is a chart illustrating examples of sounds across a range of 0 to 120 decibels.When the sound becomes 1,000 times more powerful than near total silence, it reaches 30 dB.If we increase the sound intensity by 100 times compared to near total silence, it reaches 20 dB.It is equivalent to the sound of our breathing. ![]() A sound that is 10 times more powerful than the threshold of human hearing corresponds to 10 dB.At the lowest end of the decibel scale, 0 dB represents the threshold of human hearing, where the sound is just barely audible.This is called the decibel scale or dB scale. There are different sound levels around us, the human ear has an ability to handle them, therefore, a logarithmic scale is used to express the sound levels meaningfully in more flexible numbers rather than a linear one. Product Testing: Decibel meters are employed in product testing and quality control processes for various industries, etc.Building Acoustics: Decibel meters are used in architectural and engineering applications to assess and design acoustic properties of buildings, etc.Entertainment and Event Management: Decibel meters are commonly used in the entertainment industry, including concerts, festivals, and sporting events, etc.Environmental Studies: Decibar meters are to measure noise levels and assess the impact of noise pollution on wildlife, ecosystems, and communities.Safety: Decibar meters are used to measure and monitor noise levels to ensure compliance with occupational safety standards and protect the hearing health of workers.Noise Pollution Monitoring: Decibel meters are used to measure and monitor noise levels in urban areas, industrial areas, construction sites and other environments to identify pollution issues. ![]() These are the following uses of decibel meter:
