Sounds above 85 dB are considered by specialized organizations like NIOSH (the US National Institute for Occupational Safety and Health) to be dangerous to human hearing. The range of sounds measured on the decibel scale is from 0 dB (the quietest sound) to 140 dB (the threshold of pain). We use the decibel scale to determine how loud sounds are and if they are safe or harmful to human hearing. Therefore, a 10 dB sound is 10 times more intense than a 0 dB sound, a 20 dB sound is 100 times more intense, and a 30 dB sound is 1,000 times more intense. However, the decibel scale is logarithmic, not linear. To measure a sound’s frequency, we use the hertz (Hz).Įach time a sound’s decibel level increases by 10, its intensity multiplies by 10.
To measure the noise level of different sounds, we use a measurement unit called the decibel (dB). Using this chart, you can be more aware of the noise levels that can cause hearing damage and protect your hearing. In this article, we’re using a comprehensive decibel chart of common sounds to compare different decibel levels. However, we may not always be aware of just how loud some sounds can be. The human ear is very sensitive and perceives even the smallest differences in sound intensity.
