Greetings, 
     Lower frequencies are far more efficient. That is why whales can detect 
coastlines that are 1,000 miles away, (and that is how we used to track 
submarines, but their low frequency signals). 
    Longer wavelengths have more energy  and travel farther.  The human ear, 
being more sensitive to the vocal range, tends to make us think that a brassy 
tone is more powerful because it is "louder", but out in the concert hall, 
overly lacquered hammer doesn't fill the hall as well as a softer one. 
     If you can hear a distant marching band, you will hear the bass drum 
first, the piccolo, last.
