Amplification and Assistive Devices (AAD)
Instructional Level: Intermediate
Hearing aids featuring Made-For-iPhone (MFi) technology, allow for direct streaming of audio sources from compatible Apple devices. The subjective sound quality of the streamed audio, however, may vary between devices. Using a blinded sound quality procedure, subjective ratings of sound quality for streamed audio signals were obtained for an extended bandwidth Contact Hearing Aid (CHA) and several premium Acoustic Hearing Aids (AHAs). Participants with mild to severe sensorineural hearing loss preferred the sound quality of the extended bandwidth device.
