Having a yard and garden you can be proud of and enjoy with family, neighbors and friends is one of life's simple pleasures. Unfortunately, the process of creating a garden is not always so simple. Aside from the usual concerns about watering, lawn feeding and pest control, you may occasionally find that you have to remove a tree from the landscape. The process of removing a tree requires passive noise careful planning and preparation.
Even in not so noisy environments, they can be a benefit. I'm thinking particularly of my health club. I need my music to get through my workouts, and I don't always want to crank up the volume to maximum. It's not necessarily good for your ears anyway. The club always has music playing through their speakers, and if it's crowded, then 50 or so cross trainers and treadmills running can make a lot of noise. The Sennheiser Pxc 300 passive noise canelling headsets excel in this environment.
Wear ear defenders. Exposure to excessive noise can damage hearing. Noise reducing mufflers can be fitted to machines to lessen the noise health hazard.
Take the chance to educate those around you. If they ask about your child explain that they are autistic passive noise cancelling headset explain that they interact and behave different. Use the time to educate those who are staring or looking at you.
Bass If you are the type of person that likes a lot of bass then these might not be the headphones you want, although the bass is there. It does not have as much bass as Bose.
Ear defenders- ear plugs and cotton wool won't suffice. Get yourself a set of ear defenders as continued use without them could potentially cause lasting and irreversible ear damage.
