first West. What the what is the sound intensity level in a car when the sound intensity is 0.5 micro watts per square meter? Well, we have the sound city, and we can plug it into our formulated for sound intensity level and just cranking through the map. Remember, this is lost to the base. Um, we get 57 were then asked, What is the sound intensity in the air near a jackhammer when the sound intensity level is 103? No, we can invert our equation and get an equation for sound intensity side in terms of sound intensity level. So this thing is this Expo Healthiest 10.3, and we can plug that into our calculator and we get to 0.0 times 10 to the minus two watts per meter square.
