SOLUTION: The loudness of a sound in decibels is related to the sound i, where the function for the loudness is given L(i) = 10 log10 (_i_), io and io is a constant equal to the m

Question 138446: The loudness of a sound in decibels is related to the sound i, where the function for the loudness is given L(i) = 10 log10
(_i_),
io
and io is a constant equal to the minimum sound that can be detected by the human ear. Find the loudness in decibels of a recording of rock music with intensity 10 million times io.

The loudness of a sound in decibels is related to the sound i, where the function for the loudness is given L(i) = 10 log10 [(_i_)/io]
and io is a constant equal to the minimum sound that can be detected by the human ear.
Find the loudness in decibels of a recording of rock music with intensity 10 million times io.
-----------------------------
L(10^7 io) = 10log10(10^7io/io)
= 10log10 10^7 = 10*7 = 70dB
