In the literature, you will read that square wave jerks ≈> 5 degrees can be significant. However, be careful about strict criteria when using your VNG. Using a strict criterion in measuring square wa…
In this webinar, Leigh Martin will introduce Real Ear to Coupler Difference measurements and describe two different methods of how to perform them. Leigh also has a live demonstration of the SPL meth…
