SUMMARY

The unit of sound and noise is measured in decibels (dB), which quantifies sound intensity. However, attenuation is also expressed in decibels per unit length (dB/m), indicating the loss of signal strength over distance. These two measurements serve different purposes: decibels measure sound levels, while decibels per length measure how much sound diminishes as it travels. Understanding this distinction is crucial for accurate interpretation of sound and signal loss in various applications.

PREREQUISITES
  • Basic understanding of sound theory
  • Familiarity with the concept of attenuation
  • Knowledge of measurement units in acoustics
  • Understanding of signal processing principles
NEXT STEPS
  • Research the principles of sound intensity and its measurement in decibels

Hi all,i am extremely sorry that i am asking a very basic question,The unit of sound/noise is decibels,but unit of attenuation is also decibels/length, so how it could be possible as two are different things.

I don't understand your question. You have two different quantities, each with its own units. Decibels is not the same as decibels/length.
