Step-by-step solution
dB = 10·log₁₀(I/I₀)
What Is Sound Intensity (dB)?
The sound intensity level expresses the power of a sound in decibels (dB). Because it is a logarithmic scale, every 10 dB increase means the intensity becomes ten times greater.
How is it calculated?
How Is It Calculated?
dB = 10 × log(I ÷ I₀)
I₀ = 10⁻¹² W/m² (threshold of hearing).
- Enter the sound intensity.
Frequently Asked Questions
What is the difference between 60 dB and 70 dB?
