Sounds exceeding 85 dB can lead to hearing damage. In addition to decibel level, the risk of damage will depend on two main factors: distance from the sound source and time exposed. 90 dB: lawnmower, shouting conversation; 95 dB: electric drill; 100 dB: night club, train, snowmobile; 110 dB: power saw, jackhammer, motorcycle

The decibel scale is logarithmic, meaning it increases by the power of 10 each time.
Decibel je jednotka nejznámější použitím k měření hladiny intenzity zvuku. Ve skutečnosti se jedná o obecné měřítko podílu dvou hodnot, které se užívá v mnoha oborech.

One critical thing to keep in mind with decibels is that they increase exponentially, not linearly.
