SUMMARY

The decibel level of a sound at 4% intensity of a 95dB sound is calculated using the formula dB = 10log(I/I0). By substituting I with 0.04 times the reference intensity (I0), the resulting decibel level is approximately 88dB. This calculation demonstrates the logarithmic relationship between intensity and decibel level, confirming that a decrease in intensity results in a lower decibel measurement.

PREREQUISITES
  • Understanding of logarithmic functions
  • Familiarity with the decibel scale
  • Knowledge of sound intensity concepts
  • Basic mathematical skills for calculations
NEXT STEPS
  • Study the principles of sound intensity and its relationship to decibels
  • Learn about logarithmic scales and their applications in acoustics
  • Explore the effects of sound intensity on human perception
  • Investigate tools for measuring sound levels in various environments
USEFUL FOR

Acoustics engineers, audio technicians, students studying sound physics, and anyone interested in understanding sound measurement and its implications.

What is the decibel level of a sound whose intensity is 4% that of a 95dB sound?

I know dB = 10log(I/Io) but don't know how to incorporate this for this question.

Look at incorporating the percent to the I in the formula and then use log rules to pull out the percent factor.
 
Thanks solved it
