    Calculation of intercepted sound energy
    - Given data:
    - Length of the straight line source, L = 10m
    - Surface area of the detector, A = 2.4cm2 = 2.4 × 10^-4 m2
    - Perpendicular distance from the source to the detector, r = 7m
    - Total power emitted by the source, P = 2.2 × 104 W
    - First, calculate the intensity of the sound wave at the detector:
    - Intensity, I = P / (4πr^2)
    - I = 2.2 × 104 / (4 × (22/7) × 7^2) = 22 W/m2
    - Next, calculate the sound energy intercepted by the detector in 1 second:
    - Energy intercepted, E = I × A
    - E = 22 × 2.4 × 10^-4 = 0.00528 J
    - Finally, convert the energy intercepted from Joules to milliwatts:
    - 1 Joule = 1000 milliwatts
    - Energy intercepted in mW = 0.00528 × 1000 = 5.28 mW
    Therefore, the intercepted sound energy by the detector is 5.28 mW, which is approximately equal to 5 mW.
