OBJECTIVE To evaluate the impact of venting, microphone port orientation, and compression on the electroacoustically measured directivity of directional and omnidirectional behind-the-ear hearing aids. In addition, the average directivity provided across three brands of directional and omnidirectional behind-the-ear hearing aids was compared with that provided by the open ear. DESIGN Three groups of hearing aids (four instruments in each group) representing three commercial models (a total of… CONTINUE READING
