People with autism are bothered by noise, so the British supermarket chain Morrison’s is implementing a weekly quiet hour to help them shop.

Many other shoppers are bothered by noise, including those of us with tinnitus and hyperacusis, and people with hearing loss. In fact, loud ambient noise makes it difficult if not impossible for people to converse, even those with normal hearing.

We know that retail studies show that loud background music encourages people to spend money, but we think that most people want quiet, and  loud background music drives many adults away from restaurants and stores.

And we know for sure that loud noise causes hearing loss, hypertension, diabetes, and heart disease–the scientific evidence is incontrovertible.

If enough shoppers complain to store managers about unwanted and unneeded noise, perhaps stores will become quieter.

Sound has medical uses. Music therapy has been used for decades, as has diagnostic ultrasound, e.g., echocardiography, gallbladder, and kidney ultrasound, and therapeutic ultrasound has been used in physical therapy.

Now, this report from NPR discusses the use of focused sound waves to ablate damaged brain tissue, relieving a farmer of a trembling hand.

The sounds of the unicorn of the sea

Alan Burdick, The New Yorker, writes about how researchers were able to tag six narwhals and capture the sounds they made over the course of the week, creating “an intimate sonic document of the life of the narwhal.” The researchers identified three types of sounds the narwhals make. The “first two, clicking and buzzing, are used to navigate and to hone in on prey,” and the third sound, calling, the researchers believe is used to communicate to one another.
