---

1.  What is the definition of verification? An objective measure that ensures the hearing aid is operating appropriately by analyzing the device using a hearing aid analyzer A subjective measure that captures the hearing aid user's perceived benefit, satisfaction and handicap reduction by the use of hearing aids The gold standard used to determine whether or not a hearing aid user is receiving the precise level of amplification needed at every frequency in order to achieve the bet hearing improvement possible The faculty of perceiving sounds

2.  Who sets tolerances for each test box measured values to determine quality control? APSO ANSI ASHA ICC

3.  What is OSPL 90? The maximum gain that the hearing aid can provide The typical volume setting for the hearing aid for the average user The maximum output of the hearing aid The average reading for each curve over the higher pitches

4.  THD (Total Harmonic Distortion) measurements should be less than what percentage? 35% 1% 15% 3%

5.  When should you perform test box measures? On all new and repaired hearing aids On new hearing aids only On repaired hearing aids only I don't need to run EAA because manufacturer quality control does it for me
