About This Item

 

Full Description

This standard describes a preferred thread for earhook nozzles on postauricular hearing aids. The need for such a standard arises from the wide variety of earhooks that hearing aid dispensers are required to keep in inventory to utilize different postauricular hearing aids from several manufacturers.
