Typical Sound Label on Leaf blowers
There are two basic kinds of sound label. One shows the
term "Category" and the other does not.
There are three categories, I, II, and III.
I = 65 dB(A) and lower.
II = greater than 65 dB(A) to 70 dB(A)
III = greater than 70 dB(A)
The term Category has been dropped from the ANSI Standard, which
is the governing Standard that
indicates the minimum terminology required on the label.
Some labels have not been changed to reflect this change.
The term "Category" can be ignored.
