Subjective listening effort and objective speech intelligibility will be evaluated with a new generation of a Phonak BTE (Behind-The-Ear) hearing aid.
Speech intelligibility performance will be measured with a new generation BTE hearing aid and compared to a legacy hearing aid in adults with severe to profound hearing loss.

| Speech in Noise Test | Sentences are presented to either the left or right side of the participant's head through a speaker that is 1 meter away. Background noise is presented through the remaining seven speakers that are arranged in a circular pattern around the participant. The sentences are presented at varying levels which may be both louder and softer than the fixed level of noise. The SNR50 is the Signal to Noise Ratio (SNR) at which the participant can repeat 50% of the words correctly. For example, an SNR50 of +3 means that the participant repeated 50% of the words back correctly when the sentences were presented at a level that was 3 dB louder than the noise. Lower SNR50 scores indicate better performance. | Day 14 of the study |
| Subjective measure of listening effort | A rating scale will be given to the participants following the Speech in Noise Test in which they will rate their perceived listening effort during the test. | Day 14 of the study |
