HEARING PROTECTION, SOUND, AUDIOMETRY examples of issues representative by the same key words for publications published in 2013-23, indexed in known database Web of Science CC. These terms refer to frequently occurring physical factors that threaten human health in the work environment and lead to prevention. The problem of noise exposure, as statistical data show, is still significant. For research and prepare material for comparison of results have been chosen articles affiliated by authors from Poland, Holland (Netherlands), France, Germany in that period. Examples of queries and results: in WoS CC for query (Topic = hearing protection) results = 710 documents (for All countries); (Topic = “hearing protection” AND Poland) results = 22 documents; (Topic = “hearing protection” AND France) results = 25 documents; (Topic = “hearing protection” AND Germany) results = 16 documents. Articles with affiliation of that European countries with the highest citation rates (most cited), one citation and no citations, were selected for further analysis. It seems that the number of articles focusing on aspects related to hearing testing and hearing protection is still too rare compared to the total number of articles in the area of noise, taking into account the scale of the threat of this factor. © 2024 Proceedings of the International Congress on Sound and Vibration.
