Hearing examinations in Southern Denmark (HESD): Database description and preprocessing
All hearing examinations from the public health system of the Region of Southern Denmark have been electronically recorded from 1996 to 2018 and merged into a single database, named the Hearing Examinations of Southern Denmark (HESD) database. This database contains hearing information for more than 143,000 adults, totaling 271,575 valid pure-tone audiograms. The use of this dataset, however, needs to be preceded by an intensive preprocessing procedure in order for the data to be used for research purposes. This study is aimed at describing the HESD database, as well as the preprocessing steps and rules used to classify different types of hearing loss. An initial overview of the different types of hearing profiling and their distribution among our sample is also provided.
