At a particular site, you notice that the sound intensity and the sound intensity level from a source are respectively I1 and β1. You then ask the sound crew to increase the sound until the sound intensity level (in dB) doubles and the sound intensity (in W/m2) quadruples. Determine the sound intensity level of the initial sound at your site..
