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. 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. As sound waves travel through a medium, they lose energy to the medium and are damped. Perhaps, ionosphere is responsible because solar UV radiation (SUVR) usually enhances the ionization rate whereas SUVR is absent at night. In terms of electromagnetic waves, generally higher frequency (shorter wavelength/higher energy) waves travel through objects more easily than lower frequency (longer wavelength/lower energy) waves. It travels faster in water than in air, for instance, and travels faster in wood than in water. The time to complete a cycle is the period. By running your machines at a slower, more efficient speed, frequency converters will help it to run much better for longer, which can reduce the need for maintenance and the costs that come with it. 5 Ways to Block Low Frequency Noise Install Bass Traps.
