Now let's see what this implies in terms of sound itself. As we have already seen in its pertaining section, a sinusoidal signal comprises of one single frequency Pure sinusoid, equal to the number of cycles that the sinusoid itself undergoes per second.

It is not a distortion of the truth (excuse the shakespearian pun..!) to state that this effect has literally changed music history. The birth of rock music in fact owes a lot to this effect, which was discovered by chance as a result of a wrong amplification.

High-frequencies contain less energy and therefore have a harder task in polarizing the particles on the magnetizing ribbon. This takes place when the particles are initially immobile, and therefore require, in order to overcome their inertia, a greater quantity of energy than the amount that would be necessary if they were already moving.

All magnetic material who undergo the effects of the actions of a magnetic field react in accord with a modality which is described by a so-called Hysteresis Cycle.

Before they get magnetized, magnetic particles are still and require a certain amount of initial energy to overcome inertia. Once moving they pretty much follow faithfully the magnetizing signal to saturation point.

Next we will take a look at the listed physical quantities which describe the various aspects connected to magnetism, in order to supply us with the necessary concepts to understand the ensuing sections.

The same sound is perceived as being more acute if the volume is increased considerably. The reasons for this phenomenon are not as yet still clear.
