Provide an appropriate response.The loudness of sound is measured by a unit called a decibel. A very faint, or threshold sound, has an intensity of l0, while other sounds have intensity l, which is a specified number time the threshold sound. The decibel rate is given by the formula decibel = 10 log
. Use this formula to find the decibel rating for a sound having intensity 200,000l0
