Levels Of Noise In Decibels (dB) Level Comparison Chart ...
101-125 dB: 110 decibels and above is the level where other sounds can not truly be heard. Aircraft takeoff, trains, and quite loudly concerts would fall to the 110+ decibel level. 126+ dB: 125 decibels is where sound really begins to get painful. Now, you''re basically talking about weaponized audio. This is the noise level of a rocket ship ...
