Research paper on the ear

A sound is characterized by its frequency and intensity. Mechanical forces can be steady, like the weight of this journal in your hand, or they can vibrate, like your car when it goes over speed bumps. The sound waves then hit the eardrum and the pressure of the air causes the drum to vibrate back and forth Significant progress was made during the next two decades particularly with regard to cochlear fine structure and the cellular mechanisms for converting mechanical signals to changes in electrical potentials. A century later Ernst Reissner described the presence of two distinct fluid compartments in the cochlea. This is largely because the ear does its job so well that we do not pay attention to it. Hamlet suggests that the information received by the ear or eye alone can lead to unwanted outcomes Anderson. Their work led to the concept of the ear as an elegant, but essentially passive device for converting the mechanical energy of sound into electrical signals to the brain. It even helps musicians fine tune their music to the perfect pitch. Ear Development Essay - Ear development, like all other sensory systems, evolved from lesser structures in lesser animals. The first step in this overview requires a description of the mechanical energy we call sound. By closely examining Hamlet, it becomes apparent that Shakespeare uses repetitive images of the eyes and the ears as the source from which action stems. However, as early as there were suggestions that an active mechanism might be necessary to explain the exquisite frequency resolving powers of the cochlea. However, in Act V, the world of Hamlet is turned upside-down, leaving the reader completely baffled. In addition, human social structures rely on speech communication which requires the sensitive, rapid processing of acoustic energy that the normal inner ear provides.

Included in the variety of sound systems is an array of headphones and earphones in different shapes and sizes, each with unique amplification systems.

This new sound technology had an instant and monumental impact upon our cultural imaginations that initiated the revolution in communication technologies so central to the history of the 20th century.

The ear is made up of three areas: the outer, middle, and inner ear The ear is made up of many parts that distinguish various sounds through different means.

Progress in understanding the structure and function of this tiny, relatively inaccessible organ has been slow and the milestones broadly spaced. If the piano is properly tuned, middle C has a frequency of cycles per second, high C 7 white keys to the right has a frequency of cycles per second.

It is connected to the brain by the auditory nerve and is composed of three divisions, the external ear, the middle ear, and the inner ear. By the 15th century, the presence of the ear drum and two of the three bones of the middle ear had been noted. It let us hear millions of different pitches and sound that are key for our everyday part of life. Sound is a form of mechanical energy. Mechanical forces can be steady, like the weight of this journal in your hand, or they can vibrate, like your car when it goes over speed bumps. This new sound technology had an instant and monumental impact upon our cultural imaginations that initiated the revolution in communication technologies so central to the history of the 20th century. Research based on the work of Andrea Streit however places the burden of ear development solely on vertebrates 1H. The structure of the outer ear catching sound waves as they move into the external auditory canal.

Sound - Mechanical Vibrations - Pressure Waves The sensory organs of the eye, ear, tongue and skin are each sensitive to specific forms of energy. A lack of coordination between these two senses is largely responsible for the ensuing state of things in the first four Acts Sound is generated by mechanical vibrations such as a vibrating piano string.

It contains the smallest bones, the smallest muscles, and the smallest, yet one of the most elegant organs of the body, the cochlea part of the inner ear.
