Hearing loss and high blood pressure were studied in a group of 245 men aged 56 to 68 years with 20 or more years of employment at a facility involved in fabrication and partial assembly of large metal parts. Approximately 34 percent of the men currently used blood pressure medication and 21.6 percent had a history of heart disease. Only 26.5 percent were current smokers. There was a significant loss of hearing in this worker population, particularly in the high frequencies with average mean decibel loss of 55, 62, and 61 at 3, 4, and 6 kilohertz. Some recovery was noted at 6000 and 8000 hertz. Findings were compared to those for younger workers and older, retired workers. There appeared to be an increased risk factor for hypertension in older men exposed to noise but not for younger workers. Measures of the hearing performance inventory were made to assess the communicative difficulty of hearing impaired individuals. No relationship was found between noise exposure and the incidence of high blood pressure. In the older population, tangible support, social anxiety and total score are significantly higher among noise induced individuals. No significant relationship between social support and high blood pressure was found.
