Decibel dB Range Charts - Click to Enlarge. Decibel dB is the unit used to measure a sounds strength. The decibel scale is not linear but logarithmic. This means that noise levels cant be added directly like other numbers. On the decibel scale the smallest audible sound near total silence is 0 dB. A sound 10 times more powerful is 10 dB.

May 29 2012 Besides living in a place with concrete walls or moving out to the countryside is there a way to determine if an apartment has adequate soundproofing or anything better than what I have now I know living on the top floor helps but I can hear my downstairs neighbors a little too well even with my floor covered 80.
80 to 120 dBA and power tools commonly used in construction produce sound levels up to 115 dBA. 1 The focus of this research was to determine the noise exposures of heavy construction equipment operators while documenting the workers tasks i.e. hauling moving andor pushing construction material. Time-motion studies were
Oct 02 2009 At 90 dB the exposure duration must be less than 2 hours and 31 minutes; at 100 dB the duration drops to 15 minutes at 110 dB it drops to 1 minute and 11 seconds. Also you need to consider the total daily noise dose which is a summation of all the various noise levels and durations.
