Since Audiologist don't have tools to test your HA after wearing them, and/or not willing to do it, you can use this booklet http://www.avrsono.com/documents/ImpaCt_Workbook.pdf and ask someone to test your hearing before and after wearing your HA by reading the words to you; and you repeat what you hear and also can be used as training to get used to the words you did not hear them before.
