Israel torturing Gaza residents with sonic booms (miscarriages)

Palestinians 'terrorised' by sonic boom flights




Human rights groups launched a High Court battle to stop the "physical and mental harm" to Gaza's civilian population they say is caused by Israel's new weapon against militant attacks: the sonic boom.

Miscarriages have increased sharply and children have been driven to panic by Israeli jets systematically breaking the sound barrier over Gaza, according to a petition filed with the court yesterday.

The petition, served by Physicians for Human Rights-Israel and the Gaza Community Mental Health Programme, seeks a court ruling requiring the Defence Minister, Shaul Mofaz, to halt the low-altitude supersonic flights.

The groups say the fear and damage caused, particularly to children, by the "mock air raids" - a response to two phases of about 80 Qassam rocket attacks into Israel in September and October - are a form of "collective punishment" against the civilian population as a whole and therefore violate international law. Denying this, the Israeli military says the flights are a "less threatening" alternative to artillery fire and targeted assassinations, which have also increased in response to the rocket attacks and the suicide bombing that killed five Israelis in Hadera on 26 October.

it's so much fun being Israel's neighbor

3. Would someone be so erudite as to explain the linkage

between sonic booms and miscarriages.

I "Boolean ANDed" "sonic" AND "boom" AND "miscarriage" on http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?CMD=search&DB=pubmed>, which is the NIH "PubMed" search engine, and got

4. sonic is the key word

have you ever been under a low flying jet breaking the sound barrier?

5. Etiology? Epidemiology? Peer reviewed papers? NT

6. I was wondering about this too

Such as how quickly certain people came to the conclusion that noise stress or noise pollution by itself causes miscarriages. I don't buy it. I wonder if shooting machine guns off in the streets causes miscarriages also.

7. SST Sonic Boom

Many years ago - when the SST (The Concirde and the Bigger US SST) were in the news, "sonic boom induced miscarriages" was a hot topic.

Dr Murdoch Head at GWU Med School was giving one of seminars, and this question was discussed - and dismissed - by some NIH doc.

8. good info, thanks

13. I bet homicide bombings do too - among the survivors.

9. That's because almost all available studies...

deal with incidental, not intentional and repeated exposure to sonic booms. Studies have been done on the effect of repeated incidental exposure to sonic booms on animal life and not humans, until now (shades of Mengele).

Overpressure
Sonic booms are measured in pounds per square foot of overpressure. This is the amount of the increase over the normal atmospheric pressure which surrounds us (2,116 psf/14.7 psi).

At one pound overpressure, no damage to structures would be expected.

Overpressures of 1 to 2 pounds are produced by supersonic aircraft flying at normal operating altitudes. Some public reaction could be expected between 1.5 and 2 pounds.

Rare minor damage may occur with 2 to 5 pounds overpressure.

As overpressure increases, the likelihood of structural damage and stronger public reaction also increases. Tests, however, have shown that structures in good condition have been undamaged by overpressures of up to 11 pounds.

Sonic booms produced by aircraft flying supersonic at altitudes of less than 100 feet, creating between 20 and 144 pounds overpressure, have been experienced by humans without injury.

Damage to eardrums can be expected when overpressures reach 720 pounds. Overpressures of 2160 pounds would have to be generated to produce lung damage.

If the overpressure is sufficient to shatter windows and cause structural damage, is it sufficient to dislodge an embryo from the wall of the uterus? Not a human experiment I want to participate in or support.

12. Sonic Booms

2.2.2 Sonic Booms
During supersonic flight, the shock waves generated from forward-facing portions of an aircraft are usually regions of positive overpressure. The waves originating from rear surfaces of the aircraft are typically regions of negative overpressure, or underpressure. The pressure signature is the variation in overpressure generated by the forward- and rearward-facing surfaces of an aircraft flying at supersonic speed, creating the sonic boom (Figure 3). As an aircraft reaches supersonic flight, the pressure signature is propagated along a path commonly referred to as the sonic boom ray (ray AC, Figure 4); the presssure signature is generated at the point on the flight line from which the sonic boom ray emanates (point P, Figure 4).

The sonic boom rays emanating from an aircraft operating at supersonic speed initially form a cone (Figure 4). However, due to atmospheric variations (e.g., wind and temperature gradients) the rays conform to the laws of atmospheric refraction and become horn-shaped, forming a boom conoid (Figure 5). Because all relevant refraction properties of the atmosphere are usually not known, developing an accurate boom conoid for a given supersonic flight event is difficult.

In the absence of winds, the increase in the speed of a sonic boom along a descending ray creates a decrease in the ray angle (Peterson and Gross 1972). For this reason, a boom ray tends to be refracted upward, away from the ground. Due to this phenomenon, angles from the vertical of two boom rays from each point on a supersonic flight path are sufficiently great that the boom rays only graze, or do not reach, the ground. The sonic boom "carpet" (the area on the ground that experiences the sonic boom) is defined by the locus of points of the boom rays that just graze the ground (Figure 6). Surface areas outside these points experience no sonic boom.

A tail wind behind an aircraft enhances the effect of the increase in sound speed. A head wind creates the opposite effect and tends to refract the boom rays toward the ground. Also, the paths of propagation of the atmospheric pressure disturbances depend on the manner the aircraft is flown, as well as on the prevailing atmospheric conditions.

Under certain aircraft operating conditions (e.g., acceleration, dives, turns, and climbs), the sonic boom conoids generated by the aircraft may intersect one another. This effect is known as sonic boom focusing. Such focusing may also result from refraction effects caused by variations in atmospheric sound and wind speed. Focused sonic booms may be of much greater intensity than unfocused booms and are typically generated by fighter aircraft in "dogfight" maneuvers.

IAF pilots wouldn't do that, now would they?

14. Thanks for the info...

It's a pretty horrendous thing. I've only heard it once, didn't know what the hell it was, and I thought my house was going to collapse. Just about shat my pants..

For those insisting that it's ever-so-harmless, Scurrilous posted an article in the other thread about it that talks about Israelis who are affected by it also being up in arms....
