DEFINITION of 'Aggregate Demand'. The total amount of goods and services demanded in the economy at a given overall price level and in a given time period. It is represented by the aggregate-demand curve, which describes the relationship between price levels and the quantity of output that firms are willing to provide.

Answers. Best Answer: Up to about 120 decibels, which is about as loud as a gunshot. Some of the factors that affect the loudness are energy released, the environment, and of course the distance you are from the lightning.
This accounts for the fact that decibels are logarithmic units with a base of 10 â in other words, an increase of 10 decibels means that the loudness of the sound has doubled. Our example is easy to solve. Log10(10) = 1. 1 Ã10 = 10. Therefore, the background noise in our studio has a loudness of 10 decibels.
