Unpredictability and perceived control had a greater effect than volume on task performance.
What did Kenrick & MacFarlane (1986) investigate?
The relationship between temperature and stress in drivers.
How did Kenrick & MacFarlane measure stress?
Number and duration of horn honks.
What were the results of Kenrick & MacFarlane’s study?
Higher temperatures were positively correlated with increased likelihood and duration of honking.
What did Lundberg (1976) investigate?

What was the aim of Black & Black (2007) study?
To investigate the effects of aircraft noise exposure on residents’ stress and hypertension.
What were the two core questions in Black & Black’s study?
Is health-related quality of life worse in a community chronically exposed to aircraft noise? Is long-term aircraft noise exposure associated with elevated blood pressure?
How was data collected in Black & Black’s study?
Questionnaires.
What were the two areas compared in Black & Black’s study?
Area close to airport with aircraft noise
What were the results of Black & Black’s study regarding noise annoyance?
Participants in the noise-affected area had significantly higher noise annoyance scores.
What were the results of Black & Black’s study regarding health?
Mean health score was lower for those in the aircraft noise exposure group.
What were the results of Black & Black’s study regarding blood pressure?
Long-term aircraft noise exposure was significantly associated with chronic stress and high BP.
