BS EN 60118 8 is the eighth part of an international multi series standard that covers electroacoustics techniques for testing hearing aids. BS EN 60118 8 establishes certain guidelines for simulated in situ measurements of hearing aids. BS EN 60118 8 also describes a simplified method for simulated in situ measurements of hearing aids and a description for determination of the directivity index (DI)
