All this talk about binaural beats. Just exactly exactly what are binaural beats? Let’s explore this in three steps. First, we’ll discuss what sound really is. Then we’ll define frequency. And lastly, we’ll make use of these two definitions to explain specifically exactly what binaural beats are.
Back to Basics – What is Sound?
Here’s the definition: Sound is the sensation our own brain creates (and we “hear”) when vibrations in the air cause our eardrum to move or vibrate. If you are you looking for more about Happiness Frequency look at our own internet site.
We have been surrounded by air – even though we don’t usually realize it except when the wind blows. Yet wind is a large and relatively slow movement – like the present in a stream. Sound is also the particular movement of air – yet much smaller and faster movements : like the ripples on a pond.
So , what exactly is sound? When we strike another container, for instance, the head of the drum gets pushed in. Then, because it can kind of elastic, it springs back again. But it doesn’t stop where it had been. Because it has mass it continues moving and pushes out (just like a swing continues to move to and fro after it’s pushed). Then, the particular drum head elastically snaps as well as continues until it pushes in. And so on – it continues to vibrate back and forth until it runs from energy. We see this movement as vibration because it happens numerous times a second.
That’s how sound is created – because each time the drum head pushes out, it pushes the air in front of it. Then that air pushes the air between you and the drum until the air close to your ear pushes your eardrum in. When the drum head photos back into the drum, it sucks in the air around it. And that vacuum cleaner propagates through the air and sucks your eardrum outward. So , the drum head moving back and forth forces the air between you and the drum backwards and forwards very rapidly which pushes your eardrum back and forth very rapidly. Whenever your brain senses your eardrum moving, it translates those motions to the sensation we know as sound. So it’s all about air moving back and forth : and that’s why there’s no sound in space. No air – no sound.
What is Frequency? – The Speed associated with Sound
Frequency is simply how quick those sound vibrations occur. When the drum head vibrates 100 moments per second it has a lower regularity than another drum head that vibrates at 150 times another. We hear higher frequencies because higher pitch notes. So a thin string on a guitar generates a higher pitch or tone than a fat string because it weighs much less so it can move back and forth quicker (and therefore pushes air back and forth faster). And if we fret a string, we shorten the thread and the pitch gets higher. The shorter string weighs less than a longer string (less mass) so , once again, it vibrates faster.
What are Binaural Beats? (FINALLY! )
Let’s return to our drum example – just this time, we’ll be greedy plus use two drums. If the percussion vibrate at exactly the same frequency and if they vibrate together; the sound will be twice as loud. In other words, both drums will push out at the same time so the air that pushes our eardrum will be twice as strong and then each drums sucking will tug at our eardrums with twice as much force.
