Note that since it’s not possible to put a decibel meter near many of these events and have it survive, dB levels above 200 are mostly theoretical. How Decibels Apply to Music and Sound Helpful Real Life Examples of Decibel Levels How Decibels Alter Perceived Loudness How Frequency Balance Affects. Normal Range (40 to 85 dB) Listening to these sounds poses little or no risk to the average person. Since we’ve already established that being near sounds above 200 decibels will kill you instantly, these are just here as fun facts.
