Forget Horns: Some Trains in Japan Bark Like Dogs to Scare Away Deer

In Japan, growing deer populations are causing friction on the railways. The number of deer hit by trains each year is increasing, so the Railway Technical Research Institute has come up with a novel idea for curbing the problem, according to the BBC. Researchers there are using the sound of barking dogs to scare deer away from danger zones when trains are approaching, preventing train damage, delays, and of course, deer carnage.

It’s not your standard horn. In pilot tests, Japanese researchers have attached speakers that blare out a combination of sounds designed specifically to ward off deer. First, the recording captures the animals’ attention by playing a snorting sound that deer use as an “alarm call” to warn others of danger. Then, the sound of howling dogs drives the deer away from the tracks so the train can pass.

Before this initiative, the problem of deer congregating on train tracks seemed intractable. Despite the best efforts of railways, the animals aren’t deterred by ropes, barriers, flashing lights, or even lion feces meant to repel them. Kintetsu Railway has had some success with ultrasonic waves along its Osaka line, but many rail companies are still struggling to deal with the issue. Deer flock to railroad tracks for the iron filings that pile up on the rails, using the iron as a dietary supplement. (They have also been known to lick chain link fences.)

The new deer-deterring soundtrack is particularly useful because it's relatively low-tech and would be cheap to implement. Unlike the ultrasonic plan, it doesn’t have to be set up in a particular place or require a lot of new equipment. Played through a speaker on the train, it goes wherever the train goes, and can be deployed whenever necessary. One speaker on each train could do the job for a whole railway line.

The researchers found that the recordings they designed could reduce the number of deer sightings near the train tracks by as much as 45 percent during winter nights, which typically see the highest collision rates. According to the BBC, the noises will only be used in unpopulated areas, reducing the possibility that people living near the train tracks will have to endure the sounds of dogs howling every night for the rest of their lives.

Deer aren't the only animals that Japanese railways have sought to protect against the dangers of railroad tracks. In 2015, the Suma Aqualife Park and the West Japan Railway Company teamed up to create tunnels that could serve as safer rail crossings for the turtles that kept getting hit by trains.

Remembering Sara Little Turnbull, Whose Bra Cup Design Became the N95 Mask

The coronavirus pandemic has made something of a celebrity out of the N95 mask, a particle-filtering face covering that’s long been used to protect wearers from inhaling or exhaling pathogens. (The “95” refers to the fact it can block 95 percent of airborne particles.)

Like most nondescript and pervasive products, not many people stop to think about where it came from. Now, owing to the attention placed on it as a key tool in the health care professional’s fight against coronavirus, the woman behind the mask has come to the forefront. Her name is Sara Little Turnbull, and she designed what would become the N95 based on the shape of a bra cup.

A design consultant, Turnbull was working with the 3M company in 1958 in their gift wrap and fabric division when she was exposed to Shapeen, a non-woven material made of polymers and used for decorative ribbons. Turnbull was fascinated by the molded version of Shapeen and devised the first-ever pre-made bows for gift wrap.

Turnbull didn’t stop there. She saw endless possibilities in Shapeen and assembled an audience of 3M executives to present a number of ideas she had for products—more than 100 in all—using the material. At the presentation, which she titled “Why,” she impressed 3M with the scope of Shapeen's potential. The company quickly enlisted her to work on a design for a molded bra cup.

But Turnbull had another, arguably more important notion. At the time, she was taking care of three ailing family members who were under the care of doctors. Turnbull was often in a medical setting and noticed health care workers were constantly adjusting thin masks that tied in the back. She returned to 3M with the idea of using that same molded material to make a mask that would fit more comfortably on the face.

Again, 3M saw potential in Turnbull’s idea. By 1961, they introduced a non-woven lightweight medical mask based on her concept, with elastic bands instead of strings, an aluminum nose clip, and a form-fitting "bubble" shape. (The bra patent was approved in 1962.) Though innovative, the mask couldn't block pathogens for medical use and was marketed for dust filtration instead. An improved respirator hit the market in 1972 that was suitable for other industrial purposes. As the mask’s filtration evolved, so did its usefulness. In 1995, the N95 respirator was introduced in the health care field, fulfilling Turnbull's original ambition.

Though Turnbull had been relegated to a nondescript part of 3M, she had an extensive background in design, graduating from the Parsons School of Design in 1939 and later becoming the decorating editor of House Beautiful magazine. After Turnbull wrote an article taking companies to task for not designing products suitable for the end user, she was hired by 3M. As a consultant, she also collaborated with Corning, Revlon, General Mills, and Ford, among others.

After Turnbull died in 2015, the Sara Little Turnbull Center for Design Institute was formed, which offers information to the public on the value of design and supports the efforts of disadvantaged women's design education. Turnbull's vast archive of material is available to view by appointment. A foundation in her name also provides educational grants. The “Little,” incidentally, was in acknowledgment of her height. At 4 feet, 11 inches tall, Turnbull wasn’t terribly physically imposing. But her contributions were gigantic.
