If you visit gun ranges frequently and do not protect your ears from the noise, adverse hearing problems and hearing loss can quickly occur. Young and new shooters often get caught up in the excitement of being at the range and shooting guns, and while they may protect their eyes, their ears are a different story. Appropriate eye and ear protection should be used every time you visit the range. If you wanna find out some more after reading our articles, just check out : Shooting Hearing Protection Reviews.
Noise Hazards
Few people realize that all it takes is a single gunshot to permanently lose hearing in unprotected ears. Gunfire noise is the number one non-occupational cause of hearing problems. One shot from a .357 Magnum is equivalent to over 40 hours of noise in a loud workplace. Even if permanent hearing loss does not occur, you can still experience hearing problems, such as tinnitus, hissing, humming and ear pain if you do not protect your ears from gunshot noise.
OSHA Standards
Noise is measured in decibels (dB) and OSHA, Occupational Safety and Health Administration, has set a permissible level of exposure to noise at 115 decibels for just 15 minutes. While each gun has its own decibel level, depending on how it is made and its caliber, a gunshot averages between 150 and 160-dB. According to the American Speech-Language Hearing Association and the University of Central Michigan, permanent hearing damage can occur in unprotected ears when exposed to decibel levels exceeding 140.
Noise Amplification
Additionally, as the amplitude level of noise increases, the time in which your ears go undamaged decreases. You also have to take into account where you are shooting your gun. An indoor gun range causes reverberation which can amplify the decibel level, while outdoor gun ranges allow sound waves to dissipate. Muzzle breaks and other modifications can amplify the decibel level as well.
Hearing Damage
Even small caliber guns like the .22 still produce noise levels at or just over 140-dB and pistols or big-bore rifles produce decibel levels over 175. Many people think that hearing protection hampers their shot or is unnecessary because they’ve shot before and never experienced any problems. However, hearing loss can occur from a single instance as well as be caused cumulatively. Just because you think there has been no damage sustained by your ears, it doesn’t mean that is the case. Hearing damage can occur each time you are in close range of a gunshot and that damage can add up to severe ear pain and permanent hearing loss.
Select Appropriate Ear Protection
Selecting ear protection that provides an acceptable noise reduction rating is essential for protecting your ears. The greater the noise level, the higher the noise reduction rating should be. For general gun range needs, the noise reduction rating should be no less than 25. Ear plugs only allow for minimum protection and passive ear muffs are great if you shoot infrequently or have a small caliber gun. However, if you have a loud gun or shoot often or for extended times, electronic hearing protection headsets are a great investment.
Once your hearing is gone, it does not come back, so take the necessary steps to protect your ears while you are at the gun range.
If you’re just starting out with sewing, then it might seem a bit intimidating. A lot can go wrong, from unseemly seams to mismatched pieces. If you don’t know what to do, then chances are you’ll make a few mistakes. Thankfully there are a few tips and tricks to help even the most novice beginners sew better.
1 – Get the Right Equipment.
Believe it or not, not all needles and scissors are made equal. Look for dressmaking scissors or a mat with a rotary cutter. Also select the correct needle for the materials you’ll be using (such as thicker, longer needles for upholstery work, thicker needles for denim, so on).
2 – Always Double (and Triple!) Check.
There’s a saying you’ve probably heard before ‘cut once; measure twice’. Always measure and measure and measure to ensure that you’ve got everything done right before you cut. You can always alter a garment before you cut, but once you start cutting, it becomes a lot harder. Double check your measurements, placements, and pieces (ensuring that you have 1 right and 1 left arm cut out rather than 2 right or left arms) are correct.
3 – Wash and Dry Your Fabric Before You Sew.
Wash and dry your fabric after you buy it, and before you sew it. This helps to reduce the amount of shrinkage you can expect after your finished product. This ensures that it fits you better and as it should. If you’re working with a fabric that can’t typically be washed and dried at home (like wool), take it to a dry cleaner to be pre-shrunk.
4 – Iron Pattern Pieces – and the Fabric, Too!
Iron your pattern pieces with a dry iron to ensure that you get a more accurate shape. Patterns are very easily crumpled and should be treated with care. For even more accurate results, you should also iron the fabric you intend to use (if it can be ironed).
5 – Pin the Pieces Together.
It’s much easier, whether you’re sewing by hand or with the best sewing machine for beginners, to sew close to the seam when you pin the pieces together. Always make sure, though, that you’re sewing the garment or item ‘inside out’. You will flip it right side out when you’re finished.
6 – Use the Whole Length of the Scissors.
To ensure cleaner, straighter cuts, use the entire length of your scissors when cutting. Stop right before the tip of the scissors, then start again. This will help your cuts look crisper and be easier to sew.
7 – Use a Flat Surface.
When you’re doing your cutting and other prep work, using a large, flat surface is incredibly important. Most people find that the dining room table is amply flat and large. Find a space that isn’t cluttered and has room for you to spread out all of your equipment.
Sewing is an amazing hobby and you can expect to at the very least save money with it (if not earn a little!) Don’t be afraid to experiment and have fun, but follow these basic tips and tricks for a better overall experience!

People’s lives have been immensely improved by advancements in robotics technology. What was once impossible is now already attainable.
Adaptive and assistive technology, as well as brain-computer interface and implants, are only a few of the advancements that benefited the disabled.
Adaptive Technology
People with disabilities, including the blind, have also benefited from robotics technology. In the 80s, adaptive technology for people with sight impairments was developed. Experts have developed programs capable of synthetic speech based on texts appearing on screens and later on through scanned texts.
Robotics and computers have changed lives for the better. Around the world, a lot of children cannot attend school because of hearing or visual impairments, however, because of adaptive technology, learning is made possible.
BCI Technology
It is the goal of experts developing assistive technologies to aid those who are living with physical impairments. That is why extensive studies of brain-computer interface (BCI) is constantly pursued.
While viewed by many as invasive, the advantages of using neuroprosthetics cannot be understated. Vital functions such as sensing and motor capabilities are revived. Lost limbs can now be replaced by synthetic parts capable of transmitting signals to senses. Those who are hearing impaired benefit from cochlear implants.
Brain implants have also been introduced to help those afflicted by Parkinson’s disease. A very tiny device is embedded in a particular region of the brain so that electrical impulses reaches other regions thereby triggering the required movement.
Not all BCIs are invasive. There are those that involve merely neuroimaging, functioning as an interface tool. Signals are meant to stimulate implants to trigger movement. This non-invasive method can be a substitute for surgical procedures involving the brain.
Cochlear Implant Procedures
Those who are hearing impaired benefit from cochlear implants. These implants have been popular in Europe and to date, more than 120,000 patients have benefited from it. In three years’ time, it is projected that hearing impaired children could already be receiving cochlear implants before they even reach their 5th birthday.
Ethical issues could spring from robotics and technological advancements, yet no one is blind to the glaring benefits of applying these in the lives of people today. They provide each person the opportunity to lead a healthier life and with it come the privilege to engage in work and worthwhile activities.
Would you agree to swallow a tiny robot? Maybe not, if there’s no compelling reason to. But if it’s going to help you recover from accidentally swallowing foreign material without the need of surgery, you will probably give this amazing invention a try.
There’s a robot so small and ingestible that it could be swallowed. Once inside the stomach, it can perform its function – that of closing a wound or zeroing in on foreign material found in the digestive system.
Ingestible robot
Scientists from Massachusetts have come up with biodegradable robots so minute and flexible, they can be folded up and swallowed so it could do its function. It is a minimally invasive method of fixing wounds in the stomach as it will just disintegrate once it has done its job.
The tiny robot is made of pig intestines, particularly those used as casings for sausages. It looks like a tiny caterpillar designed using origami technique. A very small magnet helps with maneuvering while inside the intestines, according to experts.
Producing a bot that can be ingested did present many challenges. The team responsible for its development said that making it function inside a person’s stomach was difficult because it had to adapt to the organ’s anatomy. It should be able to move even when it accidentally flips over.
Structure and design
The robot’s material shrinks when exposed to heat. When this takes place, slits on its surface causes the robot to fold making it look like segmented structure, like a column of boxcars.
This segmented structure allows the robot to attach itself on a surface and then break free when it flexes. It moves around via a stick-slip motion.
The stomach is filled with fluids so it has to be made to adapt to a watery environment. The team restructured the robot, modeling it after a fish fin. It is capable of swimming and crawling at the same time.
Tests on an artificial environment
The invention was tested on an artificial stomach. The stomach was structured to simulate an actual one that has foreign material, a small watch battery that has been swallowed. The objective was to test if the bot can target the watch battery and mend lacerations it has caused.
Scientists used silicone mold to line the artificial stomach and esophagus. The silicone stomach also contains a liquid that is similar to gastric juices found in the intestines.
In one of the tests, the robot was placed in a capsule made of ice. It’s as small as a pill so it can be easily swallowed. Moreover, the robot has a tiny magnet attached to it so it can be propelled towards the floating battery.
Once near the battery, it attaches to it and together they can be rolled away from the digestive tract and passed out naturally.
This amazing invention proves to be a promising one but the team has to further improve controls to make maneuvering more effective and safe.
