The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
ere'o - 10
and is the least intense sound a human ear can hear. What is the approximate loudness of a
dinner conversation with a sound intensity of 10-7?
O -58 Db
O -50 Db
O 9 Db
O 50 Db

represent the minimum audible intensity by the humans

represent the intensity for the dinner conversation

And replacing this into the formula we got:

So then the best answer for this case would be:

O 50 Db

Step-by-step explanation:

For this case we can use the following equation for decibels:

Where:

represent the minimum audible intensity by the humans

represent the intensity for the dinner conversation

And replacing this into the formula we got:

So then the best answer for this case would be:

O 50 Db
