Here is another article on noise, relating about how it affects our health (e.g., “noise can damage your heart as well as your hearing”). The article also includes reference to an app developed by the US National Institute for Occupational Safety and Health (NIOSH) – a sound level meter iOS app that utilizes sound energy, and has its accuracy verified in an acoustics lab.

 

To quote from the article something related to transport and traffic:

“As a general rule of thumb, the World Health Organization considers average road traffic noise levels above 53 decibels and average aircraft noise levels above 45 dB to be associated with adverse health outcomes, though their metrics are weighted slightly differently than the average on your screen.

Nighttime noise is considered particularly harmful because it can fragment your sleep and prompt a stress response, even if you don’t remember waking up. The W.H.O. has long recommended less than 30 dB of nighttime noise inside your bedroom for high-quality sleep.”

We tend to dismiss or take for granted the noise from transport and traffic. While it seems that it does not have an effect on our health and well-being, it will eventually catch up with us and cost us health-wise. I have downloaded and installed the NIOSH app on my phone and occasionally monitor the noise around me whether I am at home or at the office. It can get pretty loud during my commutes and I drive so am curious how loud it can be for those taking public transportation. I have experienced riding in jeepneys blaring loud music. A daily dose of that for long periods each way of the commute will surely affect one’s hearing and overall health. Exposure, after all, isn’t just about the intensity of the noise but how long you experience or endure it.
