Unnecessary vehicle noise and health, safety, and attention

Academic Literature about Noise and Health, Safety, and Attention

Horn honking used for vehicle lock confirmation has never been specifically addressed in scholarly literature about noise, safety, attention, or distraction. Most scholarly research on effects of noise is not conducted in the United States, and most of the world's other auto markets don't use horn honking to announce that a car is locked, remotely started, or for other infotainment purposes. "Only in America!" (Unfortunately, also in Canada) A German public health epidemiologist told us we would be wasting our time trying to prove its harmful effects; they've been proven, or the horn wouldn't be used to grab our attention. He said to focus on the legal status of its misuse.

At first we thought that we couldn't legitimately cite community noise, road noise, or traffic noise research in discussion of horn-based, non-emergency horn use. But lately we've been finding public health traffic noise studies that do include horn honking.

And findings of community noise, road noise, and traffic noise studies can be applied in a common sense context to many situations: those whose living space faces parking space, and anyone startled or confused by remote honking while driving, cycling, or walking. And as attention science and safety continue to evolve, automotive "futurists" might want to pay attention.

In addition to attention science, discordant horn honking is strongly related to safety because of its aggressive nature, its intended role as a safety alert, and its role in crashes, road rage incidents, and other bullying incidents that have resulted in serious injury and death. 1 2 3 4 5 6 7 8

Which again begs the question: what were product developers thinking when they decided to misuse a safety device associated with aggression, road rage, and bullying that has led to death, for a task as banal as lock confirmation? And why do they continue to add to the array of horn honking confirmation and infotainment technologies?

Environmental Noise, Disparity, and Social Justice

Social aspects of noise pollution explain why people rarely complain about noise even when it affects them greatly. Frequently cited reasons include the assumption that authorities will not take a complaint seriously, that the complaint will be a waste of time, and that the noisemaker may retaliate. Another reason cited is the fact that many people who are negatively affected by noise are already overwhelmed by trying to meet more basic needs; addressing excessive noise is given a low priority in such instances.

Quiet, Peaceful Areas, Health, and Wellbeing

Not all noise research focuses on noise. Several areas of environmental research have been converging in studies that focus on the healthy effects of quiet and silence.
