Can exposure to noise affect the 24 h blood pressure profile? Results from the HYENA study.

Unlabelled: OBJECTIVE; To study the association between exposure to transportation noise and blood pressure (BP) reduction during nighttime sleep.

Methods: 24-h ambulatory BP measurements at 15-min intervals were carried out on 149 persons living near four major European airports. Noise indicators included total and source-specific equivalent indoor noise, total number of noise events, annoyance scores for aircraft and road traffic nighttime noise.

Acute effects of night-time noise exposure on blood pressure in populations living near airports.

Aims: Within the framework of the HYENA (hypertension and exposure to noise near airports) project we investigated the effect of short-term changes of transportation or indoor noise levels on blood pressure (BP) and heart rate (HR) during night-time sleep in 140 subjects living near four major European airports.

Methods And Results: Non-invasive ambulatory BP measurements at 15 min intervals were performed. Noise was measured during the night sleeping period and recorded digitally for the identification of the source of a noise event.
