The purpose of this study is to use an optimized version of the SEDA algorithm (SEDA-HA) for hearing aids to evaluate the benefit for listeners with varying degrees of hearing loss in realistic environments and evaluate its impact on speech perception and sound quality. The primary objective is to evaluate performance with and without the SEDA-HA algorithm on speech perception and speech reception tasks. The secondary objective is to evaluate performance of and experience with SEDA-HA integrated into a portable hearing aid prototype in the laboratory and in real-world situations outside the laboratory.

Inclusion Criteria:

• 16 years of age and older
• Bilateral sensorineural hearing loss. Hearing loss will be diagnosed as sensorineural by an air-bone gap of no more than 10 dB averaged across 0.5, 1, 2, and 3 kHz and Type A tympanograms.
• Mild, moderate, or severe hearing loss. Hearing loss classification will be dependent on 4-frequency pure tone average (PTA, 0.5, 1, 2 and 4kHz) in the test ear. The mild group will have a PTA of 25-40 dB HL; moderate group will have a PTA of 41-60 dB HL; the severe group will have a PTA of 61-90 dB HL.
• Be willing and able to provide consent.

Exclusion Criteria:

• under 16 years of age
• Participants with conductive or mixed hearing loss (i.e. have more than a 10 dB air-bone gap averaged across 0.5, 1, 2, and 3 kHz or tympanograms other than Type A)

The de-identified participant data from the final research dataset will be shared upon reasonable request beginning 9 to 36 months after publication or as required by a condition of awards or supporting agreements, provided the requesting investigator executes a data use agreement with NYU Langone Health. This instance of data sharing will also require separate IRB review as well as review from NYU Langone's Data Sharing Strategy Board (DSSB). Requests should be directed to: David.Landsberger@nyulangone.org . The protocol and statistical analysis plan will be posted on Clinicaltrials.gov only as required by federal regulation or supporting awards and agreements.

Beginning 9 months and ending 36 months following article publication or as required by a condition of awards and agreements supporting the research.

The investigator who proposed to use the data will be granted access upon reasonable request. Requests should be directed to David.Landsberger@nyulangone.org To gain access, data requestors will need to sign a data access agreement. This instance of data sharing will also require separate IRB review as well as review from NYU Langone's DSSB.
