What is Soundproof Glass

There are numerous occasions when we wish, we were sitting in a room with soundproof glass; especially when we are with friends spilling out secrets. Soundproof glass help us achieve that level of privacy where conversation stay intact with no secrets been revealed to the outside world.

Soundproof glass is a type of glass which refrains sound from penetrating from one side to the other. This could either be from inside to outside or from outside to inside. Such type of glass are used by people who spend time in noisy environment. For example, people living on busy streets or cabins of noisy offices.

How Does Soundproof Glass Work 

Sound in the form of energy pass through various mediums such as solid, liquid or gas. The closer the molecules in the medium, the faster the sound energy pass from one point to another. Since the molecules of a solid medium are closely held, the sound travels faster through it. But when a soundproof glass is installed, it absorbs the sound waves and reduces vibration thus working as a barrier and preventing the sound from passing.

How can Soundproof Glass be Made

A sound proof glass can be made by simply using a thicker glass. The thicker the glass, the stiffer it would be and lesser the vibration. One of the other option to make a sound proof glass is using a material between two panes of glass. One of the most common material used for glass sound proofing is lamination. Lamination of glass is where a thin piece of plastic is placed between two glass panes. This cuts down significant amount of sound and allows noiseless atmosphere. Laminated glass work as the best soundproof glass and best soundproof windows.

How do Eyes Get Their Colour

No two people in the world have the exact same eye colour. Eye get its colour from the melanin pigment which is present in the iris. Usually when a baby is born, there is an absence of melanin and hence the baby has a blue coloured eye. The melanin is produced by the melanocyte stroma only within 6 to 36 months after birth of a child, and thus the child get its permanent eye colour then.

Very little or complete absence of melanin gives an eye it's blue colour. Adding more melanin than regular makes an eye green. Little more melanin and the eye appears in different shades of brown or hazel. The exact amount of melanin present within your iris is determined by once genetic factor.

Since melanin is not repeatedly produced by one's eye, our eyes may get little lighter or darker as time goes by. Eye colour also changes with factors like stress, medication, health problems and sickness. As we start aging the eyes increase melanin production which also can cause change in the eye colour. 

How do Fruits and Vegetables Get Their Colour

Don't we always wonder how carrots could be red or orange, eggplant are purple and grapes or lush green! Let us understand how fruits and vegetables get their rich colours. The colour of the fruits and vegetables are caused due to the pigment which are found in them. Most of these pigments are mostly chlorophyll which gives the green colour, carotenoids which give the yellow, orange and red colour and anthocyamins which give the fruits and vegetable various colours such as blues, purple and reds.

The carrot gets it's orange colour due to the presence of carotenoid pigment, carotene. Carotenoid present in the tomato namely lycopene gives the fruit it's red colour. The red berries get the red colour due to the pigment anthocymins. The red beet get it's red colour from the pigment betaleins. And the green leafy vegetables get the colour due to the pigment, chlorophyll.

These pigments present in the fruits and vegetables contain nutrients. These nutrients are beneficial for us and hence eating a particularly coloured fruit and vegetable does benefit us some way or the other. When we consume red coloured fruits, they protect our cardio-vascular system. The benefit of eating orange and yellow fruits and vegetables is it's contribution to the overall well-being of our eyes. The green vegetables work as a natural detox and the purple fruit and vegetables work as a reinforcer of an immune system.
