Sound level meters
What's the Difference Between a Class 1 and Class 2 Sound Level Meter?
In basic terms a Class 2 is not as accurate as a Class 1, which is reflected in the cost! A Class 1 meter has a better response and meets tighter tolerances than a Class 2 meter.
Whether you need a Class 1 or Class 2 depends upon the application that you will be using it for; guidance as to which Class of meter you require will be given in the BS EN standard you are following.
In general terms a Class 2 meter is appropriate for use in the world of audiology.
