The decibel scale uses the logarithmic function for representing a large range of intensities easily. We express it as Watts per square meter.Īnother more common way to express sound intensity is the decibel scale. ![]() ![]() It is equivalent to the average power per unit area. The intensity of a sound wave is measured as the rate at which it transports energy per unit area. This scale is referred to as the decibel scale. It is on 10 as the base, rather than a linear one. So, to express levels of sound meaningfully in numbers in a more manageable form, a logarithmic scale is used. If we think about it, then it would be very difficult to manufacture a sound level meter having linear performance. Thus the upper range rather than the quiet part. A sound meter uses a display with a decibel range and its resolution is further approximate to the ear’s range. When we measure the noise levels with a sound level meter, we measure the intensity of noise called decibel units (dB). The human ear can hear the sound of a pin dropping as well as the roar of a jet engine far away. It also has a remarkable ability to handle the enormous range of sound power levels. It has a clever in-built mechanism that reduces its own sensitivity with the rise of sound level. The human ear is a versatile and amazing hearing device. Source:en. Decibel Formula What is Decibel? In this topic, we will discuss the Decibel Formula with some examples. The dB is a logarithmic way of describing some ratios. Also, it is widely used in electronics, signals, and communication. The decibel (dB) is a logarithmic unit used to measure the level of sound. Also used for measuring the relative loudness of the sounds. dB is the unit for expressing the ratio between two physical quantities, generally acoustic or electric power. ![]()
