The sound level at 10 m from a single violin is 15 dB. You are seated in a concert hall, listenting to a violin ensemble comprised of 18 violins, all playing at the same intensity. That is, you are 10 m from the ensemble and each violin is producing a sound of 15 dB at your location, 10 m from the violins. The threshold of hearing is 1.0 × 1012 W/m2. What sound level are you being exposed to?

Best ResponseYou've already chosen the best response.2You do not have to take it into account since the noise level is already given at your location.

Best ResponseYou've already chosen the best response.0yes, this question is about adding decibels from effectively the same coherent source times 18. dBs cannot be added just by doing 18 x 15dB. you have to reverse back into intensities, add those up, and then calc a new decibel level that is what the question is about.
