For a sound with intensity I (in watts per square meter), the loudness L(1) of the sound (in decibels) is given by the function L(1) = 10 log- where l, is the intensity of a barely audible sound (about 10-12 watts per square meter). An artist in a recording studio turns up the volume of a track so that the intensity of the sound triples. By how many decibels does the loudness increase (numerical value)? A. 4.711 B. 4.771 C.4.171 D.4.177
