Title Research on the chronic effects of ventilation noise on man
Original title En undersökning av långtidseffekter av ventilationsbuller på människor [in Swedish]
Bibliographic information Undersöksningsrapport 1978:34, Arbetarskyddsstyrelsen, Fack, 100 26 Stockholm, Sweden, 1978. 27p. Illus. 1 ref. Price: Swe-cr.10.00.
Abstract Results of research carried out in a workplace where 54 workers were exposed to airflow noise (<92dB) over periods varying between 3 and 10 years. The sound spectrum included a large percentage of low frequencies and infrasound. Even slight noise levels had an effect on the arterial blood pressure. The authors were able to establish a significant relation between the noise level and a reduction of arterial blood pressure. They observed that the less-exposed workers used less pharmaceutical products than those exposed to louder noise. Monitoring of urinary catecholamine in the exposed workers showed relatively low levels and normal variations between periods of work and rest, showing the absence of any specific workpost stress.
