of the National Library of Medicine, in June 2023 they have made a study
confronting Over-the-Counter Self-fitting Hearing Aids (like Nebroo’s) compared with an
audiologist-fitted Hearing Aids.
“At the end of the 6-week trial, no meaningful differences were evident between
the groups on any outcome measures.”
