measured

in

environments

according

to

the

procedures

specified

by

the

American

National

Standards

Institute

(ANSI)

S12.10

and

ISO

7779

and

are

reported

in

accordance

with

ISO

9296.

Actual

sound-pressure

levels

in

a

given

location

might

exceed

the

average

values

stated

because

of

room

reflections

and

other

nearby

noise

sources.

The

declared

indicate

an

upper

below

which

a

large

number
