Just like electricity and light, sound is another form of energy. A sound is the result of air movement in pattern called sound waves, for example when you clap your hands or move something very fast. These actions are the reason that generates sound waves, which travel to your brain through your ears. Your brain processes this sound and recognizes it.

Our world is filled with many natural and man made sounds. We have gathered information on some common sounds which we hear in our daily routine and how they affect us.

Amphibians and Reptiles

Reptiles produce sounds in three different ways, which involves massive air expulsions or movements. These sounds involve air movement through modified glottis. Rubbing and vibrating of integuments are also involved. Most of these sounds were made to repel predators but in some cases used to communicate too. One can discuss about the development of these sounds as the means to send signals as well.

Animal Sounds

Scientists and observers like bird watchers are always fascinated with the different variety of sound made by different animals. They pay close attention to natural sounds like insects, frogs, mammals and birds in surrounding areas and notices that each sound is made for some specific situation.

Scientists have studied many species to understand each vocalization along with the circumstances in which they were made to determine the method of their production. Little by little these studies can help scientist understand the patterns of how and why animals made them.

It is clear though that the sound produced by animals is a mean to transfer the information. These sounds are made by the vocal cords in the respiratory system. Animals made two kinds of sounds, one vocal and other non-vocal. Only the vertebrate animals can made vocal sounds.

Musical Sounds

Any tone which has specific characteristics and has controlled pitch and timbre is called musical sound. These sounds can be produced my different instruments by a performer. A skilled performer can easily control the periodic vibration of these instruments to make melodious sounds. These melodious sounds are also called Music.

When we coordinate instrumental sounds, we make music. Making music requires arranging tones and sounds in order. This arrangement is also called composition. Music can be used to deliver emotion, experience or environment to its listeners.

The are many benefits of listening to music like improvement in mood, reduction in stress, reduced anxiety, improvement in exercise, it also improves memory, reduces pain, provides comfort and improves cognition. Best way to listen to music is through head phones. They provide isolation from other sounds around us so that we can enjoy full 3D impact of the music that we are hearing. There are best bone conduction headphones available in the market to help you enjoy the full impact of music.

Bell Sounds

A bell is an instrument which involves struck idiophone percussion. Bells are usually shaped as a hollow cup that vibrates and make strong sound waves when struck by its side. The strike can be made by both internally with clapper or uvula and externally by any object (mostly hammer). The are also made in small sphere shapes with small ball inside to make sound and called jingle bell.

Bells are usually made by hard materials but mostly a type of bronze which has its resonant properties. Each material sound different when struck. Small bells can be made with pressed metal, glass or ceramic but large bells like clock church or tower bells are mostly made of special bell metal.
Insect sounds

The insects that produce sounds in earnest are also called singing insects. Most of the insects like in the family of Orthoptera create sound by rubbing one body part with another, which is called stridulation. Some insects like katydids and crickets bodies are specially modified by nature to produce sound. They use a scraper or sharp edge on the upper surface of their wings to rub against a bump on the underside of the upper wing to make sound. These sounds are known as high pitch raspy squawks, chirps, buzzes, melodic trills and shuffles of grasshoppers and katydids.

Conclusion

Each sound affects us differently especially music. It has both positive and negative effects on our nerves and brain. We can use music to improve our mental and physical health. It can be use to boost our mood when necessary. In medieval times music was used as a powerful form of healing in many sicknesses.
