Cities and Memory, a global, collaborative sound project, has launched an intriguing project that will record sounds from the Covid-19 pandemic, entitled #StayHomeSounds:

We’re inviting anyone around the world to send us a sound recording from wherever YOU are, and tell us a little about how things are wherever you live. 

We’ll publish the results on a global sound map, so we can all share a little of our world as we go through these strange and unsettling times.

If you would like to participate, click on the second or third links above to learn more about the project and how you can become involved.

2020 is the International Year of Sound

The profession of acoustical science and engineering is a branch of physics. In the U.S., the Acoustical Society of America, for example, is a member of the American Institute of Physics. Physicists don’t communicate with the public much, but a bunch of the world’s leading acoustical science societies have declared 2020 to be “The International Year of Sound.” a “global initiative to highlight the importance of sound and related sciences and technologies for all in society.”

Watch for events in your area. For those of us concerned about the effects of noise/sound (acoustical phenomena) on health and public health, this looks interesting—even significant.

Cities and Memory has launched an interactive New York Sound Map. The map is sprinkled with markers that provide the original New York City sound recording for each site “accompanied by a reimagined version, in which an artist has remixed and recomposed the original recording to present a new perspective on the city.” Be prepared to spend some time wandering around the city.

Cities and Memory also offers sonic tourism guides to a dozen cities, including New York City.  Be sure to bookmark the site and sign up for their mailing list so you can be the first to learn about future projects.

Why do certain sounds bother some people?

Some people are bothered by common sounds that don’t bother others, such as noise from chewing. The technical name for this disorder is “misophonia.”

For many years, misophonia has been thought to be a psychological problem, but new research shows that the problem may be neurological in origin. People with misophonia have differences seen on brain scans from those without misophonia.

Medical science is replete with examples of diseases thought initially to be due to psychological causes, but later found to have biological bases. For example, stomach ulcers were long thought to be caused by stress, with a contribution from spicy food or alcohol, but then they were found to be caused by bacteria.

In the auditory field, hyperacusis–a sensitivity to sound, in which noises that don’t bother others are perceived as painful by those with this condition–was also long thought to be psychological. Then researchers found pain fibers in the auditory nerves, and the biological basis of this condition was better understood.

So kudos to the researchers studying misophonia. For those who suffer from this disorder, having the science world focus on identifying the biological basis for the problem may be the first step to treating it.

Apple Watch noise app test shows accuracy within 1%

According to this tech reviewer, an independent test of the new noise app on the Apple iWatchmeasured noise with 1% of a professional sound level meter, i.e., it measured 88 decibels when the professional meter measured showed 88.9 decibels. That’s pretty darn good!

But you don’t need the noise app on he iWatch, or any of the available smart phone sound meter apps that are available, to tell is a sound is too loud.

The World Health Organization recommends only one hour at 85 dBA to prevent hearing loss. If the ambient noise is loud enough that you have to strain to speak or to understand the person you’re speaking with, it’s above 75 A-weighted decibels* (dBA) and your hearing is in danger.

Because if something sounds too loud, it IS too loud.

*A-weighting adjusts the sound measurement for the frequencies heard in human speech.

What kind of sound should electric cars make to warn pedestrians?

This interesting article in The New York Times discusses carmakers’ efforts to choose the sound their electric cars will make. Electric motors are quieter than internal combustion motors, and regulations in Europe and the U.S. require–or will require–electric and hybrid powered vehicles to make sounds that warn pedestrians of their approach, especially the visually impaired.

National Highway Traffic Safety Administration data show that hybrid electric vehicles were 35% more likely than standard cars to be involved in a pedestrian accident, and 57% more likely to be involved in an accident with a bicycle. Personally, I think the problem may be greater for distracted pedestrians who are talking or texting on their phones than it is for the visually impaired.

If vehicles can be required to make sound, they can also be required to be quieter. So the principle of regulations about vehicle noise would appear to be without controversy. And the same principle needs to be extended to vehicles, such as the muscle cars and Harley-Davidson motorcycles also mentioned in the article, that make too much noise.

Actually, there are existing federal regulations and regulations in many states about vehicle noise, but these are rarely if ever enforced—and that needs to change.

The world’s most accessible museum?

This article in the New York Times describes the new Wellcome Museum in London, which was specifically designed to be accessible to those with visual, auditory, and mobility issues. The piece also mentions an exhibit at the Tate Museum that was inaccessible to those in wheelchairs because it had two steps at the entrance, and of a public monument to a century-old labor dispute that was also not accessible to those who couldn’t climb steps. The main idea is that those in the UK who design museums, art exhibits, and public monuments are now aware that these places, designed for the public, should be accessible to as many people as possible.

The same principle of universal access should apply to restaurant design and other public spaces. Ambient noise in restaurants makes it difficult if not impossible for those with hearing loss to understand speech. And designing restaurants and public spaces with a goal toward reducing noise levels will make it easier for everyone to converse with their dining companions, not just the hard of hearing.

Listening to the crickets

This wonderful essay in the New York Times discusses listening to the sounds crickets make at night.

We have crickets where I live, and they can be noisy. I knew that their sounds were made by male crickets rubbing their wings together in hopes of finding a mate, but who knew that crickets have strategies to amplify their sounds?

The main reason to protect our ears is to be able to hear speech, but being able to hear nature’s wonderful sounds is another good reason.

Modern music compression leaves Neil Young cold

In this wide-ranging New York Times article about musician Neil Young, I learned that Young doesn’t like modern music compression technology, which he thinks has adverse neurological effects and takes the enjoyment out of music. Music or sound compression technology erases highs and lows in volume with a loss of musical detail. I know that I find sounds on my iPhone to be tinny and it bothers my ears.

I also learned about the Tomatis Method, an auditory stimulation program that claims to improve brain function. Dr. Tomatis believed that listening to Mozart could change brain function.

I’m not sure about that, but I do like Mozart and find listening to his music soothing to my ears and my soul.
