A typical decibel level for a buzzing mosquito is 40 dB, and normal conversation is approximately 50 dB. How many buzzing mosquitoes will produce a sound intensity equal to that of normal conversation?

10.
The decibel scale is a logarithmic one, and a change of 10 dB corresponds to a 10 fold change in the sound energy.
So, if 1 mosquito would put out 40 dB, 10 would produce 50 dB and 100 mosquitoes would buzz at 60 dB.

10 would be the correct answer.
Since dB is a base 10 number a change in dB by 10 correlates with a 10:1 ratio, eg. you would need 10 mosquitos buzzing at 40dB to produce a sound at the 50dB level.

It is the unit in which sound is measured. A whisper is of about 15 decibels, a restaurant maybe from 50 to 80. A jet plane tae off produces 150 decibels minimum sound.

two mosquitos would be equal to normal conversation, because for every 10 dBs, the intensity is doubled.
p.s. i was wrong, it is 10

You have some real mean mosquitos flying around there. I believe dB has something to do with watts/cm^2 or something like that. So I would guess 100.

1.25 mosquitoes if this is true...
