I need a copy for ANSI Standard 3.22, I searched it in www.ansi.org
by the keyword 'hearing aid', but it need to pay. Does it describe the 
electroacoustic characteristics on Hearing Aid products? Anyone would be so
kind to give me a copy? It wont to be used for business.

I am a student in studying of Hearing Aid, hoping to get help from you.
BTW, i lives in China.
