Noise pollution, a serious problem ...

In developed countries it is actively considering how to handle the problem of noise pollution. Many experts say is necessary to incorporate a study of noise levels in urban planning, with the aim of creating "islands sound", ie spaces with as little noise as possible. Another solution being debated is to isolate the buildings similar to the radio studios. The problem is that this idea would be too costly.

Anyway, nothing better to take preventive measures. It is necessary to raise public awareness through education campaigns, so that the problem is recognized and that everyone can aspire to contribute and require a reduction in noise levels.

In European countries, the acceptable limit for the ambient noise is 65 db. during the day and 55 db. overnight. Hearing ability deteriorates in the band between 75 db. and 125 db. and becomes painful when they exceed 125 db., reaching the pain threshold to 140 db.

Sounds for relaxation

If a sound similar to the "hiss" from the wind or the waves, but constant and repeated is the white noise or white noise is achieved by combining all the sounds of the environment from 0 to 22,000 Hz The uses that have given this mix of sounds, is therapy for some common ailments in humans. Although it is used to soothe discomfort, is not a medical therapy.

White Noise is only an aid to control symptoms, naturally, in some cases doctors. For example, it has been recommended in patients who suffer from tinnitus (ringing, whistle or noise that a person feels constantly in the ear). White noise to help mask the buzzing and reduces the discomfort. Because of its relaxing effects, it is also used to control insomnia. In the case of babies with colic or worried, this reassures the therapy helping to reduce crying.

It is also used to mask other noises, that is, makes you miss the intensity of that sound by the action of others. For example, if a group of people holding a conversation and have white noise in your environment, no strangers to the meeting may hear it. The white noise is traded on electronic equipment developed by high technology companies, some at high cost. Also on compact discs at affordable prices.

The mystical power of music

Science has proven that music has a direct impact on the person in the body. The music penetrates the human body by varying subtlety with brain waves, breathing, heart rate, muscle tone, body temperature, the perception of space and time, and level of endorphins, which are hormones that provide a sense of well being.

For these reasons, music is the deepest chemical product that exists, both capable of stirring passions and ease tensions, to make us dance, induce happiness or sadness, and even connect with the unconscious through different atmospheres dreamlike. His mystical force can change the course of the roads making them lighter and darker open.

The newborn baby can see and hear?

Would I heard ...? Would I go ...?
Often wonder if your mom sees her son. And the answer is that not only looks but also listen and feel. From the moment of birth all the babies are trained to see and the best proof of this is that, before a stimulus bright flash, or remain with his eyes closed when there is plenty of light.

Around the second week can distinguish the face of the mother and, at the second or third month, continue moving objects. His hearing was already underway in the womb and, like the beating of the mother reassured, there are other sounds that disturbed.

Why sing in the shower?

There are people who enjoy singing in the shower mainly because it listens to itself very well.
This is because the shower works as a rudimentary recording studio: increasing the volume of sound, enhances the low and produces echo.
The tiles of the room reflect the sound over and over again in all directions, which boosts the intensity of the sound and provides a voice "potenle more."

The echo is achieved by the multitude of reflected waves that reach the ear at different times, which makes the sound of the melody is more full and rich.
Finally, the bathroom functions as a resonance chamber that amplifies the low frequencies.

A SuperPC will allow to hear the sound of the black holes

Can somebody imagine the sound of a black hole? Gobbling and gobbling titanic quantities of matter and energy. Because that is what you/they have intended some physiques of the University of Siracusa, designing a superordenador that he/she will be able to detect and to identify the celestial sounds coming from the black holes.

This SuperPC has been baptized as SUGAR (YOUR Gravity and Relativity Cluster) and very soon he/she will begin to receive big quantities of data coming from Caltech. These data have been picked up during the last two years by the Observatory of Waves Gravitations (I TIE)

The assembling of SUGAR has been carried out by a group of physiques belonging to the I TIE, a world initiative that are about detecting waves gravitacionales. These waves gravitacionales are produced by violent events in the distant universe, as the collision of black holes or the explosion of supernovas. These waves spread for the universe to the speed of the light.

The construction of the detectors TIES you were ended in 2005, and they were installed in Hanford, Washington, and Livingston, in the state of Lousiana. After being finished, with an investment of 365 million dollars, they have been two years sampling them scientifically, and you are now when the analysis of the obtained data will begin.

You are expected that as much the superordenador as the high speed network are working throughout this month. Once the data are transferred to the University of Siracusa, the physiques will be able to begin to "hear" this cosmic" "symphony.
