Do low frequency sounds really carry longer distances?
75 It is a common belief that low frequencies travel longer distances. Indeed, the bass is really what you hear when the neighbor plays his HiFi loud (Woom Woom). Try asking people around, a lot of them believe that low sounds carry longer distances. But my experience isn’t as straightforward. In particular:

https://electronics.stackexchange.com/questions/33537/why-do-higher-frequency-waves-have-better-penetration
Why do higher frequency waves have better penetration?
In free space, lower frequency signals seems to go farther because the signal is either diffracted by the ground or reflected by the upper atmospheric layers, making it actually go farther. In urban condition, where we need to penetrate walls, does 2.4GHz travel further than 433MHz radio?

2 [deleted] • 2 yr. ago Lower frequency means larger wavelengths. Larger wave lengths means the sound wave can bend around more objects where the smaller one would have hit the object, the larger wave can go around it. It’s the same idea behind why am radio travels further than pm 2 [deleted] • 2 yr. ago Optrode • 2 yr. ago

PhysicsLAB: Introduction to Sound
The molecules in the medium, as they are forced to vibrate back and forth, generate heat. Consequently, a sound wave can only propagate through a limited distance. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Hence the use of low for fog horns.

If low frequency travels longer distance, why our speech is not …
When you say lower frequency waves travel far, you are referring to electromagnetic waves that travel longer distances compared to higher frequency electromagnetic waves such TV waves. When you say speech signals do not travel long distances you are referring to acoustic waves which are mechanical waves – altogether different from EM waves.

Understanding Sound – Natural Sounds (U.S. National Park Service)
Because low frequency sounds travel farther than high frequency ones, infrasound is ideal for communicating over long distances. This figure illustrates the concepts of frequency and amplitude. The magenta wave has one half the amplitude of the black wave, and produces a quieter sound.

Radio propagation – Wikipedia
[a] At lower frequencies in the MF, LF, and VLF bands, diffraction allows radio waves to bend over hills and other obstacles, and travel beyond the horizon, following the contour of the Earth. These are called surface waves or ground wave propagation. AM broadcast and amateur radio stations use ground waves to cover their listening areas.

In short, longer wavelengths travel further but carry less information; shorter wavelengths have shorter ranges but can carry more information. An aside about frequencies and wavelengths. To unpack all of this a little more, wavelength and frequency are related. Longer wavelengths have lower frequencies; shorter wavelengths have higher .

Frequency and Distance
First, it is said that lower frequency sound waves do travel further because they do not lose as much energy to the medium – in this case, air -that they are moving through. 1 This can explain the downward trend we saw with the frequencies; 146.832Hz, 195.998Hz, 261.626Hz, and 349.228Hz.

Subject question: Low frequency do travel further than high frequency on earth because the high frequency wave lengths are more easily absorbed by the molecules in the air. First Comment question: Attenuation is the gradual loss of energy which will in most cases happen over distance. lesoutrali bot
