The level of noise in decibels

can be measured using a decibel meter. Decibels represent a logarithmic scale, so small changes in the number of decibels actually represent large changes in the intensity of the sound. The threshold for human hearing is around 0 decibels, with normal conversation typically measuring around 60-70 decibels. Prolonged exposure to sounds above 85 decibels can cause hearing damage, so it's important to protect your ears in loud environments.
