On this track you will find a very simple "Just for the Hell of It" hearing test. Listen to the instructions and the 8 tones beginning with 20 Hz, 60Hz, 120Hz, 240Hz, 480Hz, 7000Hz (7kHz), 10000Hz (10kHz), and finally the 20000Hz (20kHz). At birth the normal human ear can hear between 20Hz and 20kHz. As we age we lose the ability to hear some of the frequencies. Any sound 85dB or higher puts excessive air pressure on the eardrums and over time can permanently damage our hearing. Hearing damage is cumulative. Take care of your hearing so you listen to Heirloom Radio... a Different Kind of Oldies Program. This track will be stored in the "History of Radio" Playlist
