Background: For children with hearing loss, the benefits of FM systems in overcoming deleterious effects of noise, distance, and reverberation have led to recommendations for use beyond classroom settings. It is important that audiologists who recommend and fit these devices understand the rationale and procedures underlying fitting and verification.

Objectives: This article reviews previousguidelines for FM verification, addresses technological advances, and introduces verification procedures appropriate for current FM and hearing-aid technology.

Methods: Previous guidelines for verification of FM systems are reviewed. Those recommendations that are appropriate for current technology are addressed, as are procedures that are no longer adequate for hearing aids and FM systems utilizing more complex processing than in the past. Technological advances are discussed, and an updated approach to FM verification is proposed.

Conclusions: Approaches to verification andfitting of FM systems must keep pace with advances in hearing-aid and FM technology. The transparency approach addressed in this paper is recommended for verification of FM systems coupled to hearing aids.
