The Invaluable Uses Of Sunglasses In Sports

Sunglasses were first invented for use by airline pilots who had to endure the sun’s bright rays on their eyes when flying towards it. However, in the years since, people have found several different uses for them. Got into a fight lately? Suffering from a bruised and swollen eye? Just wear sunglasses and you’re good to go! Funny, but it is indeed true. Sunglasses have become a vital part of our world. However, they’ve become vital even in the world of sports, or at least some sports in particular. Let’s now take a look at some of the invaluable uses of sunglasses in sports.


If there’s one sport that is synonymous with ‘outdoors’, it has to be cycling. Cyclists roam from city to city in the open outdoors, often enduring dust, dirt and pollution on the motor highways. That’s not all; cycling races are almost never called off due to bad weather. They simply ride though blazing heat, pouring thunderstorms and even a snowstorm. There have been instances when riders have suffered from frostbite due to prolonged exposure to the snow! The fact that they have something to protect their eyes makes sunglasses an invaluable addition to the sport.

Beach Volleyball:

Sand is an excellent reflector of sunlight. The lighter the color of the sand, the more sunlight it reflects. This makes playing sports such as beach volleyball in broad daylight, an extremely cumbersome process. There might be direct sunlight glare and in addition to that, there would be the sunlight reflected from the sand, making life difficult for the players. Fortunately, with the introduction of sunglasses, the players are able to overcome this obstacle. Nowadays, sunglasses specifically designed to be light and apt for beach volleyball, such as wood grain sunglasses have hit the market.


Just like beach sand, water also reflects sunlight. In fact, water actually disperses the incoming sunlight in several random directions. This causes a severe glare to athletes taking part in sports such as rowing. However, thanks to the availability of highly polarized sunglasses, these athletes can take part without any fear of sunlight glare affecting their performance.


Cricket matches are played for 5 continuous days. That’s 5 days out in the open in countries where the normal day-time temperature is often above 100 degrees. One of the most important aspects of the game is catching the ball and when the sun is out there, blazing into your eyes, it often becomes nearly impossible. That’s why sunglasses have become a very important part of the sport.

Noise Cancellation And Noise Isolation In Headphones Explained

Noise Cancellation is often dubbed the perfect accessory for urban survival. Living in the cities, we usually encounter extremely high levels of static noise, often raging between 65 to 70 dB. We may not realize it but this noise keeps getting processed by our brain and over time it starts causing headaches and even hearing damage. Constant travelers also benefit greatly from Noise Cancellation headphones, as the headphones silence out the constant rumble from vehicle (motorrad bluetooth headset) and jet engines. Let’s now take a look at how Noise Cancellation and Noise Isolation works in headphones.

Noise Isolation:

Noise isolation is the simplest and oldest form of blocking out loud noises. What is it, you ask? Well, closing your ears is noise isolation. You see, sound requires a medium to travel through. So if you block out that air medium by placing your hands over your ears, you essentially create noise isolation. This is exactly what noise isolation headphones try to do. Noise isolation headphones create either a solid blocking surface completely over your ear openings, or create a layer of vacuum between the headphone and your ear, thereby preventing the sound from reaching your ear.

Although Noise Isolation has been around for ages, its use in making headphones better is fairly recent. Since it doesn’t require any additional power to function, noise isolation is the technique of choice that is used to make low-cost headphones sound better.

Noise Cancellation:

In 1978, the founder of Bose, Mr. Amar Bose was traveling in an airplane and found that he couldn’t listen to the in-flight entertainment program properly due to the constant rumbling of the jet engine. So he immediately set up a dedicated research facility in his company to study noise cancellation techniques. About, a decade later, Bose launched the World’s first active noise cancellation headphones. Let’s take a look at the science behind this wonderful technology.

In noise cancellation headphones, there are super sensitive microphones located on the outside of the headphones. These pick up the noise that is coming in from the surroundings. There are drivers inside the headphones that process these noise waves and then produce the exact counter wave to these noise signals. These two cancel each other out and the wearer hears total silence. Although this sounds perfect, the technology is still developing and at the moment, noise cancellation headphones work really well with low-frequency noise such as jet engine rumble but fails when encountering high-frequency noise such as the cries of a baby.
