That graph comes from this extremely detailed article on outdoor sound propagation. EDIT: I was thinking about electromagnetic and sound waves when I posted this question. Does a square wave "smooth out" in the air? 1 Why low frequency can travel longer distance? Perhaps, ionosphere is responsible because solar UV radiation (SUVR) usually enhances the ionization rate whereas SUVR is absent at night. Thus, the transmitted power is constant. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications. Reflection occurs at the ionospheric E layer or F layers. Originally Answered: Why does lower frequency Radio Waves travels farther than shorter ones? Mr. Enright's answer addresses the first, taught us a lot, and answered the basic question. This has to do with the way that sound waves are generated. (a) A low frequency signal is modulation for the following purposes : (i) It reduces the wavelength of transmitted signal and the minimum height of antenna for effective communication is / 4. In the visible spectrum, light is something like 500nm, which can be similar to the size of air molecules. Use Soundproof Curtains or Blinds. Because of that, heat makes sound travel faster, too.

In particular: So with very weak sounds, high frequencies seem to travel further? The proximity effect means lower frequencies are picked up the, But wavelength is porportional to the inverse of frequency, so saying "actually it's about wavelength" is equivalent to saying it's about frequency, @BinaryFunt If it is sound wave it can be vary in speed so in each situation it could be same frequency but difference wavelength and vice versa. Due to the penetration power of high frequency radio waves in general, is the major limitation of FM staions where the AM uses ionosphere for reflection and hence it covers more distance. The energy of sound may dissipate along distance by many cause at the same rate in any frequency, Low frequency wave not carry in "longer distance" than high frequency. The frequency of a wave is inversely proportional to its wavelength. I wonder over what length scale that occurs, but perhaps it's worth a separate question.

Also, in AM the transmitted power goes waste in the transmitted carrier. 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. However, if we say that a wave has a frequency of 60 cycles per hour, points on the wave may be traveling faster or slower depending on wavelength. So adding higher harmonics makes notes sound louder. They also allow a wider band for modulating signals, so you can obtain higher frequency transmission. Not all radio waves travel farther at night than during the day, but some, short and medium wave, which AM radio signals fall under, definitely can given . Bass sounds have wavelength about the size of the objects and waveguides in their path, whereas higher sounds are progressively deeper into the ray optics regime. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium.

The reason is that EM radiation at higher frequencies are more susceptible to reflection. Does it depend on the amplitude or energy of the wave? The low frequency sounds bend over the wall and return to the ground. Do low frequency waves carry longer distance than high frequency waves? Whenever you give molecules a "push" you're going to lose some energy to heat. As the name suggests, bass traps absorb low-frequency sounds. At some distance from a highway, what do we hear? You also have the option to opt-out of these cookies. Is email scraping still a thing for spammers. We hear the lower-pitch rumble enhanced over the higher pitches. How to distinct between far loud voice and near soft voice? The distance that the sound needs to travel is one of the key considerations in determining the frequency of the signal. Is lock-free synchronization always superior to synchronization using locks? Higher frequency sound can be reflected by both small and large objects. How long is MOT certificate normally valid? Even if the low frequencies are reaching your ear, it's harder for you to hear them. 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. This website uses cookies to improve your experience while you navigate through the website. Or perhaps high frequencies are reflected more by walls than low frequencies?
