Formula: Δ L = 10 × log n.
<span>Δ L = level difference. </span>
<span>n = number of equal loud sound sources. </span>
n = 5
10 × log10 5 = +<span>6.9897</span><span> dB compared to the case that only one source is available. </span>
5 + 3 = 2/7p - 115 + 3 = 2p/7 - 11
8 = 2p/7 - 11
8 + 11 = 2p/7
19 = 2p/7
19 × 7 = 2p
133 = 2p
133/2 = p
p = 133/2
The answer is: p = 133/2 or p = 66.5.
I believe it is the first one because it is an exponential growth rate.
