Being subjected to increased noise levels can adversely affect both health and work productivity. The study showed that most of the basic school teachers (77.9%) had bad knowledge, while a few of them (22.1%) had good knowledge. Also, a majority of basic school teachers (76.1%) demonstrated a negative attitude regarding the significance of noise reduction within the school environment, as well as aspects such as audiometry, hearing loss, and the adoption of hearing protection devices. In contrast, 23.9% of teachers held a positive attitude. Regarding their practices, a substantial portion of teachers (66.3%) exhibited bad practices concerning audiometric testing, the supply and utilization of hearing protection devices, and health and safety training, while a smaller percentage (33.7%) adhered to commendable practices in these areas. Additionally, the research showed that the daytime noise levels recorded in the schools exceeded the EPA of Ghana and the WHO’s acceptable thresholds, which stand at 55 decibels (dBA). With a long exposure duration (10+ years), most of the teachers developed mild NIHL. The elevated noise levels in the basic schools also made most of the teachers less productive. Therefore, it was established that the population of basic school teachers within the Old Tafo Municipality is prone to developing NIHL due to the unacceptable noise levels in the schools’ environment. However, it is argued that not all of the teachers will actually develop NIHL, despite the findings this study provides. The incidence of NIHL was greater among the cases (70%) in contrast to the controls (40%). The outputs from the KAP assessment indicate a lack of education and training concerning noise exposure and hearing loss among school teachers. Additionally, there is an absence of audiometric testing, inadequate provision of hearing protection devices, and little to no health and safety training. In conclusion, the elevated ambient noise levels of the basic schools impair normal hearing and make the exposed teachers less productive. The study recommends that preventive and awareness campaigns be raised in the municipality in addition to the planting of bamboo trees.
