Hearing impairment, deafness or hearing loss is a partial or total inability to hear. It is caused by many different factors, including but not limited to age, noise, illness, chemicals and physical trauma. There is a diagnosis to determine the severity of the hearing impairment, and it is measured in decibels. It may be ranked as mild, moderate, moderately severe, severe or profound. There are a number of measures that can be taken to prevent hearing loss, but in some cases it is impossible to reverse or prevent. Many new technological advancements have been made to improve the hearing of those who are hearing impaired. However, some of these technologies have caused controversy in the deaf community. Deaf Studies are academic disciplines concerned with the study of the deaf social life of human groups and individuals including anthropology, economics, geography, history, political science, psychology, social studies, and sociology. The Deaf studies comprise the scientific study of the deaf-related aspects of the world. Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
