the answer for 4b is 64.8db. please show the work

4. The formula B = 10log ( T. ) can be used to calculate the sound level, B decibels, where I is the intensity of the sound and I, is a reference intensity equal to 10 W/m . A conversation between two people is approximately 60 dB, while the threshold of pain caused by sound is considered to be 130 dB. a. Determine how many times as intense the threshold of pain is than a conversation. the answer for you is 10% Please show the work = lag CT bo Determine the sound level to the nearest tenth of a decibel if the conversation intensity is 6 frippled
