Longer-range diffraction also occurs due to changes in the density of the air. Does low or high frequency travel faster? The very simplistic explanation is: lower frequency waves travel further because they can interact with (bounce off) the ionosphere under certain conditions, whereas frequencies above a few 10s of MHz cannot bounce off the ionosphere. Sometimes, the least expensive way to increase range is to use a bigger antenna, a higher antenna, a more efficient antenna, or a directional antenna. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Because of that, heat makes sound travel faster, too. And I'm actually simplified the imagination that size(of wave) is match up with the size(of object) to determine it will pass through or not. Now that you've considered 3 times as many effects as would warrant a good answer, here's another to ponder :) Any real medium will have dispersive and diffusive effects. 2 Does higher frequency mean better signal? Depending on the application, you can shape the speaker(s) so you have cylindrical waves, or dipole waves, or sections of a monopole wave , or a combination of several patterns. Low frequency waves can also occasionally travel long distances by reflecting from the ionosphere (the actual mechanism is one of refraction ), although this method, called skywave or "skip" propagation, is not as common as at higher frequencies. Low frequency radio waves do not travel very far through the atmosphere and are absorbed rather quickly. These cookies ensure basic functionalities and security features of the website, anonymously. Similarly, high frequency sound will result in more molecular collisions, which will increase energy loss there. You're right though that in general terms, lower frequency waves are diffracted more.
