How to protect yourself from the LRAD as a protestor in Kenya:
Long Range Acoustic Devices (pictured below) produce high-frequency sound waves that can cause you permanent hearing loss. The waves travel like light in a straight line, but for the Kenyan version, there are 4 cones to send the sonic wave in all directions.
And since maandamano will end when CoK 2010 ends, the first defense is blocking that line of sight to the machine with thick and heavy materials.
1. DIY Hard Sound Deflector: use wooden doors or thick plywood found in loose building materials, construction site scraps. Hold a thick piece of wood in front of your head to reflect the sound waves away.
2. Use metal cooking pots, sufurias or large metal trays directly over your ears and face. Thick metal acts as a hard barrier as sound waves struggle to pass through. Direct the aluminium side to the waves. It seems Kioni and his sufuria revolution was onto something.
3. Use heavy plastic bins, buckets to create a makeshift shield. They are easily available in the streets.
4. Pack thick books or directories in your backpack. Hold the backpack flat against your head and ears like a helmet.
5. Improvise ear Plugs and muffs using wet cloth or fabric. Tear strips of denim, heavy canvas, or thick cotton from clothing or bags. Wet the fabric with water, roll it into tight, dense cones, and push them firmly into your ear canals. Wetting the fabric packs the fibers closer together, making it much harder for sound to pass through.
6. Use firm rubber, plastic caps, bottle caps or rubber stoppers from juice or soda bottles. Wrap them in a layer of cloth and press them tightly into your ear openings.
7. If you have nothing else, press the palms of your hands completely flat and hard against your ears. Cupping your hands creates an air pocket that can actually amplify the sound; you must press flat and hard to seal the canal completely.
8. Combine with 7 above and turn away. Do not look directly at the LRAD. Turn your back completely to the sound source so your skull, back, and shoulders act as a first wall of tissue to block the sound from hitting your ear canals directly.
9. Get behind others with shields. If someone near you has managed to construct a larger wooden or plastic shield, press tightly behind them. Create a straight human line directly behind the barrier to stay out of the acoustic line.
Contrary to popular belief, dont use noise cancelling headphones. The sonic wave can intefere and create dangerous static right i side your ears, defeating the purpose of protecting yourself.

@KenyanSays They used the wrong mask.the "hackers mask" worldwide.Or maybe to pass the message of hijacking another party of tunataka power. time will tell
