We also would like to provide some information on our sone ratings:
A sone is a measurement of sound in terms of comfortable hearing level for an average listener. The lower the sone value, the more comfortable the listening environment. Sones are not decibels or volume, but rather how sound is "sensed".
• 1 Sone is the sound of an average refrigerator.
• 2 Sones is a sound of a quiet office.
• 3 Sones is a sound TV makes when set at a comfortable volume.
• 4 Sones is how loud normal talking is.
• 5 Sones is basically a louder conversation.
• 6 Sones is equivalent to a sound in a quiet restaurant.
• 7 Sones is a sound we hear on a quiet traffic street.
• 8 Sones is a sound we hear on an average loud traffic street.
• 9-10 Sones is the loudness of a busy traffic street.
Note: Sones are a better measure than decibels because sones are linear (2 sones is twice as loud as 1 sone as opposed to decibels which are logarithmic - 66 decibels is twice as loud as 60 decibels).
