According to Krisp.ai, the long story of how noise cancelling or if you prefer noise reduction headphones all started in Germany in 1933 when Paul Lueg, a doctor of philosophy and medicine, submitted a ground breaking patent application about using phase-advancing waves to cancel sinusoidal tones in ducts and inverting polarity to cancel sounds around a loudspeaker. This went on to become what we today call active noise cancellation. In active noise cancellation, all that is needed is a secondary sound B to cancel out the un-needed sound A.
This system was also designed to reduce noise for the pilot in the cockpit area and help make the communication easier. Fogel was considered to be the inventor of active noise cancellation and he created one of the first noise cancelling headphones systems.
NOISE CANCELLING HEADPHONES: THE BASICS
Active noise control dates back to the 1930s, and noise cancelling headphones were part of the story for a while now. The first companies that started producing them were Bose and Sennheiser
Some of the noises that need cancellation may include.
Passive noise cancellation
Active noise cancellation
Adaptive noise cancellation

● 1 in 8 children have permanent hearing damage. ● Children are extra sensitive to sound and therefore suffer hearing damage more quickly. ● According to the World Health Organization, exposure to loud noise is one of the most common causes of hearing damage. ● Noise can overstrain young children leading to stress and sleeping problems. ● 95% of children sometimes suffer from an ear infection due to loud noise exposure.
There are no known disadvantages of using protective ear gear for babies, on the contrally, babies and kids need to be armed with noise–cancelling headphones. Infants and young children have particularly delicate eardrums that can easily be damaged by repeated exposure to loud sounds (anything louder than 70 decibels), which can lead to hearing problems.
We have already mentioned something about reacher grabbers and the special role they play in bettering the lives of people with disability, are elderly or battling with arthritis or Parkinson’s disease. The unger grabber tool has been proved to be the best among all the other pick up tools for elderly. In this article though, we look at the Ez reacher, another great grabbing tool.

People with Arthritis, stroke and Parkinson’s disease will find it hard to pick stuff either when they are lying on the ground or when they are way high above them. Grocery shopping for example is extremely hard for people with arthritis because their muscles might just decide to stiffen up when they are picking vegetables up the shelves of the grocery store. For one bending might be a really painful thing and even impossible especially for the case of those with physical handicap. Parkinson’s patients also have dyskinesia and dystonia which causes muscle stiffness. They are therefore not able to move around or pick things in far off places.
Thanks to technology though, they are still able to move around and do things by using reacher grabbers for handicapped that are uniquely designed to give them extra hand extension as well as ability to hold up as much weight as possible. There are even those tools that are magnetically fitted so that they can do special tasks such as picking car keys, belts, earrings or anything else that is metallic and can be attracted by the magnet fitted in the tool.
What to look out for when buying your grabbing tool
Length—you want something that offers maximum extension say from 32” and above
2. Durability—you are looking for a tool that is highly durable and will last for a long time therefore giving you value for your money.
3. Sturdiness—the tool needs to be strong and sturdy enough so that you do not have to worry about it breaking easily or catching rust that could affect its effectiveness.
4. Weight limit—you want a tool that will be able to pick high loads of weight without giving in or breaking apart
5. Foldability and flexibility—look out for a tool that can easily be folded so as to save on storage space
6. Picking even the smallest of things—you want a tool that will pick even the least of things be it a dime or even a needle
7. Adaptability—you are looking for a reacher grabber that will be adaptable even on a wheelchair
8. Ergonomic—when you buy tools for people with arthritis and Parkinson’s disease, you are looking out for tools that are ergonomic and comfy to use by them without creating any unneeded muscle stiffening.
