In music a very soft sound called "pianississimo" (ppp) might have an intensity of about 10^−8w/m^2. a very loud sound called "fortississimo" (fff) might have an intensity of about 10^−2w/m^2. /0 is 10−12 w/m^2 for sound. a. convert the intensity of "pianississimo" to intensity level (units of db).b. convert the intensity of "fortississimo" to intensity level (units of db).
