## Abstract

The Food and Drug Administration (FDA) is amending its regulations governing hearing aid labeling to reference the most recent version of the consensus standard used to determine the technical data to be included in labeling for hearing aids. This amendment is being made in order that manufacturers may use state-of-the-art methods to address technical data in hearing aid labeling. FDA is amending the regulations in accordance with its direct final rule procedures. Elsewhere in this issue of the Federal Register, FDA is publishing a companion proposed rule under FDA's usual procedures for notice and comment to provide a procedural framework to finalize the rule in the event the agency receives a significant adverse comment and withdraws this direct final rule.
