High power animal chasers have changed everything ...
Unbelivable, there was no research done before starting,
and to do a reliable research after the damage is already done, some
devices have to be banned for some decades before starting
The Mosquito is a low powered animal chaser used against our youth and children. The risk to the target group is relatively low assuming that the mosquito noise is not predominated by street noise or loud music, and that the the youths are aware of the danger and leave the area immediately when the device is "working". But small children and infants are very much at risk through lengthy exposure to the sound because the average adults themselves do not perceive the noise. The noise generates a huge workload leading to oxidative hair cell death.
Small children and infants exposed long enough to "Mosquito" sound become deaf to animal chaser frequencies, just like average adults. They will never complain about the noise of animal chaser, nor will they feel any pain or be aware of any danger. A fate many other children will share. High powered animal chasers work over a far wider range, doing the same damage as the Mosquito but a lot faster.
Audible or inaudible. Stereocilia is continually moved by animal chaser sound as too is the nonfunctional stereocilia on already dead hair cells. The shorter the distance to the animal chaser the higher the risk of worsening damage. Stereocilia is the weak point in the ear. The pain threshold is the simple warning that this weak point will soon be damaged. Commercially available animal chasers are easily exceeding this pain threshold by about 30 dB (1'000x) to 50 dB (100'000x). This means up to 100'000x more power than the threshold level. Decibel (dB) is a logarithmic unit. 30 dB more means 1'000x more power, 50 dB more means 100'000x more power. Just 10x above the warning level poses a real danger of breaking off or rooting out stereocilia. Above this figure, damage becomes unavoidable.
Amputated stereocilia unravel a whole range of phenomena. Acoustic shock often causes tinnitus resulting in deafness many years later. This is explainable with physical behaviour. For all the effects it is easy to prove that all those phenomena existed a long time before the first animal chaser appeared. Since gunpowder was discovered.
An electron microscope photo shows stereocilia moving in the inner ear. To obtain such a photo a slice of the cochlea has to be cut out. There is no technique available to look into the cochlea without destroying it!
- The stentorian sound of a high powered animal chaser breaks off or uproots stereocilia. Ultrasonic tones are received on the outermost part of the spiral cochlea where the most damage is done, but it is also possible that an inner part of spiral cochlea is slightly damaged at
4kHz or 6kHz).
Most children try at least to protect their ears whereas most adults are deaf to animal chasers. Probably painless, and unaware of any danger they let the noise of the high power animal chaser unhindered into the ears to break off or uproot stereocilia of former already nonfunctional hair cell in cochlea.
- Stereocilia are never replaced and once damaged remain so for their lifetime. Cochlea is filled with a lymph fluid. This fluid conserves stereocilia. The amputated stereocilia are conserved by the fluid too and become a real danger as everlasting debris. At loud noise levels that debris is moving to and fro like bullets in the cochlea.
- The inner ear is a closed system. At best the broken off debris will remain in the vicinity they were broken and at least cause no further damage. Sound waves, however, may drive the debris outwards or inwards. The outward equilibrium organ will be disturbed. Inward hearing loss will slowly effect lower frequencies.
Should there also be debris in the second possibly damaged area (3kHz,
4kHz or 6kHz) used for speech and music, then loud noise will damage the hearing ability within both lower and higher frequencies in this area too, thus music and speech becomes less audible!
A thousand explanations, three causes, one common ground. With few exceptions, tinnitus is always a result of a defect in the inner ear.
Tinnitus as phantom
Tinnitus is common, phantom pain is it not. Phantom pain can be made worse by stress, anxiety, weather changes and many other uncountable things. The same goes for tinnitus. Causes and therapies against phantom pain and tinnitus are often the same. No wonder, with a lot of amputated stereocilia tinnitus is sort of phantom pain...
Tinnitus from debris
Through sound waves and vibration, debris moves within the inner ear from damaged to undamaged areas. When a lot of stereocilia are touched in several places by a lot of debris at the same time then random noise is heard. At loud sound levels debris can also become lodged between intact stereocilia and cause continuous tones. The source of the sound is usually then blamed on such things as a motor cycle, a loud voice, a disco. Many things things that never used to hurt and were often heard with no illeffects. Never suspected is the animal chaser that created all that debris.
With luck tinnitus may disappear. When lymph fluid is slightly warmed its consistence becomes more liquid and the blockage may be relieved. But the debris still exists, the danger remains and loud noise may never be allowed again.
Tinnitus and WLAN
WLAN uses frequencies from 2,412 GHz to 2,472 GHz.
Bluetooth uses 2,400 GHz to 2,485 GHz. Right in the middle the
microwave oven use 2,455 GHz. Microwave ovens heat food in the same frequency range as WLAN radiates through walls for internet access. For hair cells WLAN works like a mini power microwave oven ...
The permitted energy limit for WLAN is 10 W/m² at 2,4 GHz. WLAN enters the injured inner ear and "heats" hair cells. Hair cells can receive energy from sound or from WLAN. The energy level can be compared:
WLAN < = > Sound
10 W/m² = 130 dB
0,2 W/m² = 113 dB
0,1 μW/m² = 50 dB
An intact hair cell will probably dissipate the WLAN energy through stereocilia into the lymph fluid. But what if a full or partially functional hair cell was decapitated from the stereocilia and never fully died afterwards? Contaminated by amputated stereocilia, hair cells cannot dissipate the energy from WLAN into the lymph fluid.
Injured body parts react differently to healthy body parts. Headache and tinnitus are often diagnosed in connection with WLAN. Headache and tinnitus are also often diagnosed after acoustic shock.
Hardness of hearing / Hyperacusis
Debris swimming in lymph fluid increases existing damage caused by loud noise, whereas exactly the same loud noise with pure lymph fluid would have been of no consequence. After exposure to loud noise and fierce movement of stereocilia, the hearing ability is normally regenerated during rest. But stereocilia accidentally hit and broken off by high speed debris will never recover. Not only is the damage increased but also the amount of debris increases too, thus increasing the danger of further damage. The longer the exposure to loud noise, the higher the risk that this will occur. The damage wanders slowly deeper into the cochlea and the ability to hear high tones slowly diminishes. Most dangerous are the frequencies within the transition zones between damaged and damaged cochlea.
Hyperacusis (over-sensitivity to noise): A lot of debris is spread over a wide area with functional hearing ability. Constantly debris hits stereocilia. Sound levels which are quite harmless to pure lymph fluid can pose a real threat to the remaining hearing ability of those affected. Pain warns of this danger. The pain threshold for the person concerned is lower, giving the impression of over-sensitivity. If tinnitus is already apparent in the area, then further noise will increase the loudness of this tinnitus.
Noise-induced hearing loss (NIHL): Tinnitus should be treated as an alarm. But we are told to ignore it. Some debris wide spread in the cochlea can, at loud noise levels, cause a chain reaction, hitting more and more stereocilia causing more and more debris. Without warning in a very short time wide parts of hair cells in the cochlea can be irreversibly damaged, leaving a lot of debris spread over a wide range causing hyperacusis.
Acute hearing loss
Uprooted stereocilia can lead to swelling. Should the uprooted stereocilia build a cluster of debris a bottleneck is formed. Sound waves will reach stereocilia behind this bottleneck, but in suppressed form, producing a feeling like cotton in the ear. Considerable hearing loss is frightening. Light hearing loss will only be recognized if one ear is more affected than the other. When the swell disappears and the cluster dissolves the hearing ability seems to come back with no adverse effects.
What is wrong with Stereocilia-Hypothesis?
The Stereocilia-Hypothesis suggests that inconsiderable, harmless hearing damage caused by animal chasers is in fact quite considerable albeit unnoticed hearing damage. People that financed the harmlessness will do everything to protect their invested money and to prove the hypothesis untrue.
