Decibel (dB) is a term used to measure sound intensity. This concept, abbreviated as dB, is used as a criterion for how a sound can be perceived by the human ear. Thus, as the value on the dB scale increases, the sound becomes louder. As the dB scale decreases, the sound correspondingly becomes quieter.
A decibel meter can be simply defined as a device that measures sound level pressure to determine sound intensity. Sound enters the decibel meter through a microphone input. Subsequently, the sound is evaluated inside the device and displayed on the screen in decibel units. Decibel meters, manufactured according to high industrial standards, are designed to provide accurate measurements and results. They are easy to use and lightweight in construction.
Due to the portable nature of the decibel meter, you can perform measurements on the go and easily carry it to different locations for quick results. It is also possible to make fixed measurements with the same decibel meter. The same device can be used for both types of usage.
The subjective concept of noise can be difficult to understand and measure. In general, what is called noise varies from person to person. In this case, to make an accurate noise measurement, it is necessary to use a decibel meter.
The decibel meter is especially important in urban and high-traffic areas where noise levels are high. To measure and prevent noise, which affects everyone, the decibel meter is used.
How are decibels measured?
The intensity of every sound you hear in daily life varies depending on the distance. The perception of sound intensity by humans is called loudness. Therefore, to make accurate measurements related to sound, you need to be close to the sound source.
When measuring noise levels with a decibel meter, several factors can directly affect the measurement. These factors are:
Distance between the decibel meter and the sound source
Direction of the noise source
Measurement made outdoors (where noise can disperse) or indoors (where noise can reverberate)
For the decibel measurement results to be useful, attention must be paid to the conditions under which the measurement is made. In particular, the distance to the noise source will directly influence the decibel measurement results.
