|Hearing aids journals deal with the publication of science-oriented novel work, driven by studies in the field of hearing aids. The hearing aids journals make available all recent and quality works coming within the scopes of the hearing aids for a researchers reference. This in turn will keep accelerating the scientific discoveries in the realms of hearing aids. Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results. Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
