The use of a logarithmic scale in measuring sound intensity in decibels allows for a wider range of values to be represented in a more manageable way. This scale compresses the range of sound levels into a more easily understandable format, making it easier to compare and analyze different levels of sound intensity.
The logarithmic nature of the decibel scale means that each increase of 10 decibels represents a tenfold increase in sound intensity. This affects the way we measure and perceive sound levels because small changes in decibels can correspond to large changes in actual sound intensity. As a result, our perception of sound levels may not always accurately reflect the actual increase in intensity.
An increase in sound intensity is known as a rise or an increase in volume, while a decrease is referred to as a fall or decrease in volume. Sound intensity is measured in decibels (dB), with a higher number indicating a louder sound and a lower number indicating a quieter sound. This rise and fall in sound intensity can affect our perception of sound and its impact on our ears.
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.
Intensity does not affect wavelength. Wavelength is determined by the frequency of the wave and remains constant in a given medium regardless of the intensity of the wave. Intensity, on the other hand, is related to the amplitude of the wave, which determines the brightness or loudness of the wave.
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.

Lever length refers to joint flexion or extension. Longer is a higher intensity and shorter is less intensity.
Lux and candela are both units of measurement for light intensity, but they measure different aspects of light. Lux measures the amount of light that falls on a surface, while candela measures the brightness of a light source in a specific direction. Lux is used to determine the brightness of an illuminated area, while candela is used to measure the intensity of a light source. In essence, lux measures the light that is received, while candela measures the light that is emitted.
