Title Hemodynamic reactions to monotonous work performed in silence and in noise of 70dB(A)
Bibliographic information Jan.1989, Vol.2, No.1, p.51-61. 28 ref.
Abstract Haemodynamic parameters (cardiac contraction rate, ejection volume, arterial blood pressure and total vascular peripheral resistance) were evaluated in women during monotonous work lasting 4h, accompanied by moderate exercise, and during monotonous visual work performed under laboratory conditions. Subsequently, the effect of noise levels of 70dB(A) on haemodynamic parameters was evaluated. It was found that noise did not affect work efficiency, but it did cause an increase in ejection volume and a rise in arterial (especially diastolic) blood pressure. Thus noise levels of 70dB(A) cause an increase of physiological effort of work.
