SUMMARY
The conversion between decibels (dB) and intensity in watts per square meter (W/m²) is established using the formula B = (10 dB) log₁₀(I/I₀), where I₀ is the reference intensity of 1.0 x 10^-12 W/m². To solve for intensity (I), the equation can be rearranged to I = I₀ * 10^(B/10 dB). This method allows for straightforward conversions between dB and W/m², essential for various applications in acoustics and signal processing.
