The sound from a busy highway contains a 500 Hz Fouriercomponent whose power at the highway is 1.5 ✕ 10−6watt/m. (Ignore sound interactions with the ground).
(a)What are the sound intensity (in W/m2), the soundintensity level (in dB) and the loudness (in phon) of that Fouriercomponent at a distance of 25 m from the highway?
intensity=?Ă‚Â Ă‚Â W/m2
intensity level =? dB
loudness=?Ă‚Â Ă‚Â phon
(b)What are the sound intensity (in W/m2), the soundintensity level (in dB) and the loudness (in phon) of that Fouriercomponent at a distance of 50 m from the highway?
