Answer:
BdB = 68.10 decibels
Step-by-step explanation:
BdB = 10 log10 I / Io
where BdB is the sound intensity level in decibels, I is the sound intensity on the linear scale (W / m²) and I0 is the hearing threshold (10^-12 W / m²).
Converting Io de 10^-12 W/m² to W/in², tenemos
10^-12 W/m² = 1.5500031000062x10^-9 W/in²
So, applying the equation or formula,
BdB = 10 log10 (10 ^ -2 W/in² / 1.5500031000062x10^-9 W/in²
)
BdB = 10 log10 (0.64516x10^6)
BdB = 10 log10 (6,451,600)
Being log10 (6,451,600) = 6.8096674332398761189214526331036, then
BdB = 10 x 6.8096674332398761189214526331036
BdB = 68.096674332398761189214526331036
BdB = 68.10 decibels
