Oh my.
I've never heard of this sort of thing.
Frank, sound comes from waves that enter the ear to be jumbled about in the inner ear and sent to the brain to decode the waves.
For those that work for years in a high noise job even wearing ear plugs or muffs, some company's have their employees take a hearing test each year.
Reason is sound waves bounce off the whole body, including the skull, not just the ears. Some waves jangle the nerves as finger nails or chalk on a chalk board.
Sound warfare has been around since Joshia blasted the gates to Jericho in the Bible. If you Frank have ever hit your funny bone in your elbow, some sound waves produce the same feeling in your head.
We see these programs where the high pitch of an Opera singer will shatter Christal glasses, I imagine the pitch that can break a glass has some bad effect on the people also.
The jaw is perfect as a transmitter of sound waves, without the inner ear to to send these messages to the brain to be decoded, constant waves cause confusion and migraines. To block off the inner ear with plugs and muffs, it becomes very annoying to work 10 hours a day asking everyone to repeat themselves or to have to yourself have to repeat yourself.
The very reason riggers will direct cranes with hand movements, good to know that special language in case the 2 way radios go down.
As you Frank are deaf, you can still pick up vibrations that effect your body, these vibrations are sound waves that one may not hear with their ears but is felt by the flesh and bones of people, animals, those that in case of impending earth quake head for higher ground.
Zulus knew the effect of sound waves in the Boa War, constant pounding on the ground by the thousands to cause intimidation of the enemy, days and nights of constant drumming, it literely drove some to commit suicide.
Frank, the incidence of people on antidepressants may well be because their body's and brains have an over load of Noise, sound waves. The noise of everyday life, crying children, then off to work in a world of noise for 8-10 hours, home to crying kids, neighbors fighting, street sounds, sudden and abrupt. TV, Radio and perhaps the phone ringing off the hook. Off to bed for 6-8 hours with sleep interupted by dogs barking, motorcycles, ambulances and police cars.
Our world has changed from one of occasional noise to that of unrelenting assult on our body's. You dear Frank may be more mentally healthier then those that must live under assult from man made sound waves 24/7 for life.
