Sound levels refer to the intensity of sound, measured in decibels (dB). The decibel scale is logarithmic, meaning that an increase of 10 dB represents a tenfold increase in sound intensity. For example, normal conversation is around 60 dB, while a rock concert can reach levels of 110 dB or more. Prolonged exposure to sounds above 85 dB can lead to hearing damage. Different environments have varying sound levels. In nature, a whisper might be around 30 dB, while a busy street can reach 80 dB. Understanding sound levels is important for protecting hearing and ensuring a comfortable auditory environment in places like homes, offices, and public spaces.
