Question
Find the decibel level of each sound.(a) noisy restaurant: $I=10^{8} I_{0}$(b) farm tractor: $I=\left(5.340 \times 10^{9}\right) I_{0}$(c) snowmobile: $I=31,622,776,600 I_{0}$
Step 1
Now, we can calculate the decibel level for each sound: (a) Noisy restaurant: Decibel level = 10 * log10(10^8 * I0 / I0) Decibel level = 10 * log10(10^8) Decibel level = 10 * 8 Decibel level = 80 dB (b) Farm tractor: Show more…
