A mosquito's buzz is often related with a decibel rating of 40 Db. Normal conversation is often rated at 60 Db. How many times more intense is normal conversation compared to a mosquito's buzz?

Dear Student ,
Normal conversation is 20 dB more intense . This 20 dB corresponds to 2 Bel difference .This difference is equivalent to a sound which is 100 times more intense .Always raise 10 to a power which is equivalent to difference in Bels .
