Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. In most cases, you use transistors (and/or tubes) to amplify the RF signal from the transmitter. Diffraction is more pronounced through a small opening, where small is compared to a wavelength. Mr. Enright's answer addresses the first, taught us a lot, and answered the basic question. As sound waves travel through a medium, they lose energy to the medium and are damped. A sound wave at 100 Hz within the range of most male speech has a length of just 3.4 meters. A frequency translation method is designed to shift low frequency signals to intermediate frequen- cies in order to utilize higher-frequency components. Even a good pair of headphones like Sennheiser HD-650 struggle with lower frequencies: So if it sounds like high frequencies travel farther with headphones, it's because headphones are poor at producing low frequencies and your ear is poor at picking them up. Air molecules, such as N2, O2, CO2 are roughly 3 to 4 ngstroms in diameter. Low frequency (low energy) light has a longer wavelength than high frequency (high energy) light, and is usually much closer to the size of molecules.
