Sones Vs Db New! Online

If you are buying , look for dBA (A-weighted decibels). The "A" weighting adjusts the raw dB measurement to mimic the human ear's frequency response. This is the standard for safety and industrial equipment.

The human ear does not hear all frequencies equally. For instance, a low-pitched hum and a high-pitched whistle might have the same decibel level, but the whistle will sound much louder and more annoying to us. Sone ratings account for this biological bias. sones vs db
