Going to 2 callers will add 3 db to the sound level, which is on a logarithmic scale. Doubling to 4 will add 3 db more.
Eight will add 3 db, making a total of 119 dB. You need ten callers to add 10 dB to the sound level of one caller.
That should have been obvious from the definition of dB.
In a pig-calling contest, a caller produces a sound with an intensity level of 110 dB.
How many such callers would be required to reach the pain level of 120 dB?
