06 Part 2 Acoustical Rules of thumb and Demystifying the Decibel
Tuesday, 3 December, 2019
When comparing decibel values, that best way to think about it is to consider how decibel values combine. For example, the combination of a sound having a level of 50 dB, and a second sound having an equal sound level of 50 dB is 53 dB. In shorthand (but not arithmetically correct) 50 dB, quote-unquote, plus 50 dB is 53 dB. This gives us a good rule of thumb to live by: Two equal sound levels combine to be 3 decibels greater than the individual. 65 dB "+" 65 dB = 68 dB When two sound levels differ by 10 decibels or more, when combined, the lesser level can be ignored. 65 dB + 75 dB = 75 dB Learn more about our company at www.ussi.com.
