the sensitive auditory nerves of older people makes the difference in preference. But understanding can patch up the difference. Lowering the volume of sounds can make a big difference in respect to the older people. Pop music is definitely not a noise. It is a very expressive means to bring happiness‚ sadness‚ fear and hopes. It may pass many changes in tempo‚ rhythm and beat but the soul in every pop song will always be there. This is the most artful and most beautiful way of bringing out the innermost

the introduction of contaminants into a natural environment that causes instability‚ disorder‚ harm or discomfort to the ecosystem i.e. physical systems or living organisms.[1] Pollution can take the form of chemical substances or energy‚ such as noise‚ heat‚ or light. Pollutants‚ the elements of pollution‚ can be foreign substances or energies‚ or naturally occurring; when naturally occurring‚ they are considered contaminants when they exceed natural levels. The major forms of pollution are listed

additive noise is characteristic of almost all communication systems. This additive noise typically arises from thermal noise generated by random motion of electrons in the conductors comprising the receiver. In a communication system the thermal noise having the greatest effect on system performance is generated at and before the first stage of amplification. This point in a communication system is where the desired signal takes the lowest power level and consequently the thermal noise has the

LNA Design Iulian Rosu‚ YO3DAC / VA3IUL http://www.qsl.net/va3iul/ An LNA combines a low noise figure‚ reasonable gain‚ and stability without oscillation over entire useful frequency range. The Low Noise Amplifier (LNA) always operates in Class A‚ typically at 15-20% of its maximum useful current. Class A is characterized by a bias point more or less at the center of maximum current and voltage capability of the device used‚ and by RF current and voltages that are sufficiently small relative

“A Powerful Noise” was a moving documentary about the hardships women face across the globe focusing on three key issues‚ HIV‚ lack of education and economic hardship. From this documentary some clarity I received really opened my eyes to how these issues affect women around the world. I learned that HIV is not primarily spread through sexual intercourse but rather through sharing needles in impoverished countries. I was always aware that sharing needles is a way of obtaining

Prof. BERESFORD TALK ABOUT THE PROBLEMS OF POLUTION (Tape script‚ slightly abridged) Pollution is today‚ probably‚ the greatest problem that faces mankind. There is a saying in English that it is an ill bird that fouls its own nest. And human beings are‚ collectively speaking‚ fouling their nest at the increasing rate. It is an alarming picture. We are polluting the air‚ which we need to breathe‚ the earth from which we derive all our food‚ and the waters from which wе‚ of course‚ derive the
