https://info.5y1.org/equation-for-sound-intensity-decibel_1_7c7c89.html
The defining equation for decibel levels is: dB = 10 log(Intensity 1/Intensity at threshold) For one jack hammer this is 130 dB and so solving this . 130 = 10 x log(Intensity 1/1x10-12) 13 = log(Intensity 1/1x10-12) Intensity for one jackhammer (Intensity 1) = 10 Wm-2. For two jackhammers the intensity …

The decibel scale is a logarithmic scale for measuring the sound intensity level. Because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in changes by a multiplicative factor.

The following equation is used to compute the intensity of sound: dB = 10 log (I / Io) where . dB. represents decibels, I. is the intensity of the sound in question (measured in joules per second per square meter), and . Io (read as "I naught" ) is the softest sound the human ear can distinguish, being 10-12 joules per second per square meter.

The sensation of loudness is known to be proportional to the intensity of sound (You don’t need to know what the intensity is yet.), and it is measured as the decibel level, which is defined by β(dB) = 10log₁₀(I/I₀), where I is the intensity of the sound and I₀ is called the reference intensity.
