How Do Sound Waves Affect Human Hearing

Aim: The aim of this project is to determine the ear's ability to allow us to perceive the pitch of sounds by detection of the wave's frequencies, the loudness of sound by detection of the wave's amplitude and the timbre of the sound by the detection of the various frequencies that make up a complex sound wave. Introduction: Understanding how humans hear is a complex subject involving the fields of physiology, psychology and acoustics. The ear consists of three basic parts - the outer ear, the middle ear, and the inner ear. Each part of the ear serves a specific purpose in the task of detecting and interpreting sound. The outer ear serves to collect and channel sound to the middle ear.

Although cerebral palsy is known for greatly impacting physical development, it can also impact you intellectually. Aphasia is the loss of partial verbal expression, making pronouncing words more difficult. Dysarthria is abnormalities of facial muscle tone which makes it harder to make and control facial movements. (Speech and Language…., n.d, p. 1). These conditions can all be apart of the symptoms and affects of cerebral

Cognitive processes include: speech, reasoning, the ability to solve problems and make judgments, as well as the ability to store and recall memories. The impairment of cognitive processes makes it hard to impossible for the patient to complete a task as easy as going out to throw garbage. Individuals that experience cognitive impairment may experience emotional outbursts and be frustrated at times. They may also push away people that are trying to help and isolate themselves, making the problem worse (Psych

George, the father of Harrison, can is talked about how is sense of hearing affected him. He had a “ little mental handicap radio in his ear” was required by law to wear it since he is intelligence was above normal. Every once in awhile, a buzzer would go off in his ear, causing him to become distorted. Then as George was watching television, there were ballerinas on set but, they were all weighed down. “ They were

Sacks describes a man who escapes it through playing Bach on the piano. For a man who thinks he has over forty thousand tics a day to be able to escape that for a few minutes just by playing his favorite songs is incredible. He doesn 't believe that his tics just disappear, however; he believes that they are just harnessed and focused. He says that he “was simultaneously feeding and fuelling my tourette’s by giving it a thing it so craved: touch.” (SOURCE) Parkinson’s Disease Parkinson’s is very similar to tourette’s, but in parkinson’s the natural rhythm of our body is gone, and all of their movements are very shaky and jerky, and sometimes faster or slower than they should be. It’s almost like their whole body is stuttering.

It might be obvious that music impacts people physically, but understanding how music and the brain interact is a deep study and a mystery. Music can have an affect on brain development. One of the first things that occurs when music enters the brain is the “triggering of pleasure centers”, this releases dopamine, a feeling that makes you happy. The response is so quick that the brain can anticipate the most pleasurable peaks in familiar music, and that can cause the early dopamine rush (Golstein). Along with affecting the brain music has a certain impact on emotions.

Abstract Brain connectivity is one of the most enigmatic question posed to neuro-biologists. The establishment of this intricate network in prenates and neonates brain is influenced in equal measures by environmental and biological factors. In it's extension, certain environmental stimulation boost the parameters for improved brain connectivity. One such factor is auditory stimulation. It is widely believed that use of such stimulation increases cognitive functions.

This is known because on the website npr.org it says “Even the smallest dose of power can change a person.” (When, 16) Prince Humperdinck throughout the whole story was consumed with power, but when he found that power wasn’t an option against love he didn’t know what to do. This is also known because it also says on that website that “When people felt power, they really did have more trouble getting inside another person's head.” (When, 16) When Humperdinck felt the power, he couldn’t even stop a simple person from falling in

In addition, Musicologist Julius Portnoy states that music has the ability to change metabolic rates, effect blood pressure, and even digestion. According to his research classical music was found to have a calming effect on the body and increase feel good hormones such as endorphins. To such an extent that 30 minutes equal to the effect of a single does of Valium. In contrast music has been also shown to cause sickness and act like a poison to the body. Loud rock music caused plants to die, and soft classical music made them grow faster.

- Some people hear a hissing or roaring sound. Subjective tinnitus is a kind of tinnitus that can only be heard by the patient, which can be caused by ear problems, auditory nerve issues, and disturbances in the auditory pathways. Objective tinnitus is a kind of tinnitus that can also be heard by a physician during an examination. Objective tinnitus is rare and may be caused by multiple factors, such as problems with the blood vessel, condition related to the middle ear bone or muscle contractions. Other possible causes include exposure to noise, diseases, drugs, stress, and head injuries.
