Therefore, the power radiated into the space increases and signal can travel larger distance. Does high or low frequency travels faster? Thus, diffraction may aid sound dispersion and DIFFUSION. This is also shown in the Figure below. Nice. Where is the original statue of The Thinker located? The higher harmonics make the note sound louder partly because they add extra power to the sound wave, but also because our ears become more sensitive as the frequency increases with increasing frequency (at least up to about a kHz). How to distinct between far loud voice and near soft voice? That's because sound is a pressure wave that relies on moving molecules around to get where it's going, and it can get there faster or slower depending on what those molecules are like. From Wikipedia (Wavelengths), "The wavelengths of sound frequencies audible to the human ear (20 Hz20 kHz) are thus between approximately 17 m and 17 mm, respectively." Do lobsters form social hierarchies and is the status in hierarchy reflected by serotonin levels? How do I forgive myself for ruining my life? If it weren't for attenuation (absorption) sound would follow an inverse square law. So in the inaudible range we have only 020 Hz in the lows but post 20kHz theres a lot more room.
