WebSound levels are mostly stated at the frequencies 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, and 8kHz. These individual sound levels are added together using a logarithmic scale to determine the overall sound level. We won’t go into this logarithmic addition process here - that would be too much for this blog. http://www.inertance.com/engineering-calculator/dba/ can you draw dicks on twitch
