Decibel (dB) - Unit used to express the intensity of a sound wave in logarithmic ratios to the base of ten. Sounds of different frequencies need to be from 0-20 dB in intensity to be heard by normal ears. If more than 20 dB is needed, then further hearing evaluation would be recommended. #Wordoftheweek | Hearing Health Foundation
