Patients with hearing impairment who do not have a Cochlear implant

Patients with hearing impairment who have a single-sided implant (using a hearing aid on the opposite ear)

Participants with hearing loss will be fitted with the Phonak Audéo Sphere™ Infinio (PAI) hearing aid with artificial intelligence (AI)-based noise reduction, which incorporates deep neural networks (DNN) technology to reduce background noise.

Speech stimuli, presented at a comfortable level of approximately 60 dB SPL (like normal conversation), will be delivered via a loudspeaker positioned directly in front of the participant.

They will be tested in 3 listening environments: quiet, moderate noise, high noise.

Speech perception scores will be measured as a function of each hearing aid program setting: quiet setting, moderate noise, and advanced AI-based reduction for high noise.

Participants will listen to a list of 50 words and repeat each word aloud. Results are reported as a percentage of correctly repeated words out of 50.

Participants will listen to a list of 20 sentences and repeat each sentence aloud. Results are reported as a percentage of correctly repeated sentences out of 20.
