Objective:
To investigate the hearing loss and speech disorders in the elderly, to analyze the risk factors of the elderly deafness, as well as to provide reference for the clinical research of the elderly deafness.
Methods:
From March 2016 to March 2018, 913 elderly people, who were tested for hearing and speech disorders, were examined by a unified questionnaire to investigate the demographic data of the subjects and the related factors of deafness, and the hearing and speech recognition tests were carried out. According to the hearing loss, the hearing impaired group was divided into the hearing impaired group (500, 1 000, 2 000 and 4 000 Hz, the average hearing threshold>25 dBHL) and the non hearing impaired group (the average hearing threshold of the four frequencies ≤25 dBHL), and then the single factor analysis and the unconditional
