How much salary can I expect in Dublin Ireland after an MS in data analytics for a year? Why exactly do higher frequency (>240 Hz) sounds on Mars travel ~4% faster than lower frequencies? When I stand near someone who's listening loud music in headphones, it is the high pitched sounds that I hear (tchts tchts), not the bass. For one low frequency waves have less energy than high frequency waves and therefore lose less energy as they travel through the air. 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. Required fields are marked *. Assuming two frequencies from the ISM band: 2.45 GHz and 5.8 GHz. Originally Answered: Why does lower frequency Radio Waves travels farther than shorter ones? The low frequency sounds bend over the wall and return to the ground. So if you're listening from far away, you'll mostly hear those treble frequencies and little or no bass. 4 What is the advantage of converting a frequency?
