    The sound intensity is still the same. The sound intensity level does not depend on the number of sound sources but only the wave properties of the wave medium and the properties of the sound source. The wave properties of the medium includes the density and also the temperature.

    61.7 dB

    Explanation:

    The sound intensity of Rifle can be calculated using this formula

    I (sound intensity) = 10 * log (I / IO) equation 1

    where I = power/area

    I = 64.7 dB

    hence equation 1 becomes

    64.7 = 10 * log (I / IO) equation 2

    note the sound intensity was produced by 2 identical rifle hence equation 2 will become

    64.7 = 10 * log (2P / PO) equation 3

    for a single rifle (X) equation 3 becomes

    = 64.7 - 10 * log (2) = 64.7 - 10*0.30 = 64.7 - 3

    = 61.7 dB
