Detecting Sound

How Our Ears Detect Sound

"Sound waves are detected by the fact that the waves can cause objects to vibrate. The vibrations from the sound waves must be converted into a signal and then amplified and processed. Your ear and a microphone are common detectors of sound."

"Just as a vibrating object creates sound, thus forming compression waves in air or some other medium, sound is also detected by the waves causing a back-and-forth vibration of some object in its path."

"What is happening is that the sound in traveling from the air into the object, just like you can hear sound going through the walls or windows in your house."

"Since the vibrations are so small in most situations, you cannot tell that the object is actually vibrating. However, you can feel how sound can cause other things to vibrate by standing in front of some loudspeakers when music is being played very loud. You can actually feel the vibration on your skin and chest."

"Loud sounds in a room can cause the windows and even walls to vibrate noticeably at the frequency of the waveform."

"Sound waves can cause some objects to vibrate, allowing for detection of the sound. The vibrations from the sound waves must be converted into a signal—usually an electrical signal—and then amplified and processed. Your ear and a microphone are common detectors of sound."

According to the website: http://www.school-for-champions.com/science/sound_detection.htm

Our ears transform and change sound waves into electrical signals that allow us to hear. The outer ear collects and receives sound waves. The vibration then travel to the middle of your ear. very tiny organs increase and largen the size of the vibrations. These vibrations are picked up by organs in our inner ear. Our inner ear changes vibrations into electrical signals that our brain interprets and receives as a sound.

How the Human Ear Works

Our ears change sound waves into electrical signals that allow you to hear. The outer ear collects sound waves. Then the vibrations go to the middle of your ear. Very tiny organs of the ear increase the size of the vibrations in the middle ear. The vibrations then are picked up by organs in our inner ear. The inner ear changes vibrations into electrical signals that our brain interprets as sound.


How the Human Ear Works

The outer ear - acts like a funnel for sound waves, the pinna (this is the auricle. It is the visible part of the ear) gathers sound waves and shows them into the ear canal.

The middle ear - three bones: the hammer, anvil, and stirrup. They act as levers to enlarge the size of vibrations entered through the out ear.

The inner ear - vibrations created by sound are changed into electrical signals for the brain to explain and interpret.






In the ear drum (this is a lightly stretched membrane that is the opening to the middle ear), sound waves vibrate.

The vibration in the ear drum then makes the hammer vibrate as well, which also makes the anvil and stirrup vibrate.

The stirrup then vibrated the oval window (opening to the inner ear).

The vibrations in the oval window make waves in the liquid inside of the cochlea (the spiral cavity of the inner ear).

Movement of the liquid cause very small hair cells inside the cochlea to bend.
The bending of those tiny hairs stimulate nerves, which then sends electrical signals to the ear.

Life Story of Pope John XXIII

POPE JOHN XXIII

1958-1963

" On October 20, 1958, the cardinals assembled in conclave, and elected Angelo Roncalli as pope. Many regarded him because of his age and ambiguous reputation. Little realizing that the pontificate of this man of 76 years would mark a turning point in history and initiate a new age for the Church. He took the name of John in honor of the precursor and the beloved disciple. But also because it was the name of a long line of popes whose term to be pope  had been short.

Angelo Giuseppe Roncalli, the third of thirteen children, was born on November 25, 1881 at Sotto il Monte (Bergamo) of a family of sharecroppers. He attended elementary school in the town, was tutored by a priest of Carvico, and at the age of twelve entered the seminary at Bergamo.

A scholarship from the Cerasoli Foundation (1901) enabled him to go on to the Apollinaris in Rome where he studied under (among others) Umberto Benigni, the Church historian. He interrupted his studies for service in the Italian Army but returned to the seminary, completed his work for a doctorate in theology, and was ordained in 1904. 

Continuing his studies in canon law, he was appointed secretary to the new bishop of Bergamo, Giacomo Radini-Tedeschi. Angelo served this social-minded prelate for nine years, acquiring first-hand experience and a broad understanding of the problems of the working class. He also taught apologetics, church history, and patrology.

In 1921, he was called to Rome to reorganize the Society for the Propagation of the Faith. He immediately concerned himself with the problems of the Eastern Churches. 

Transferred in 1934 to Turkey and Greece as apostolic delegate, he set up an office in Istanbul for locating prisoners of war. In 1944 he was appointed nuncio to Paris to assist in the Church's post-war efforts in France, and became the first permanent observer of the Holy See at UNESCO, addressing its sixth and seventh general assemblies in 1951 and 1952. 

In 1953 he became cardinal-patriarch of Venice, and expected to spend his last years there in pastoral work. He was correcting proofs of the synodal Acts of his first diocesan Synod (1958) when he was called to Rome to participate in the conclave that elected him pope.

Since his death on June 3, 1963, much has been written and spoken about the warmth and holiness of the beloved Pope John. Perhaps the testimony of the world was best expressed by a newspaper drawing of the earth shrouded in mourning with the simple caption, "A Death in the Family." "

My thoughts:

My own personal view of Pope John's life is that it was very outspokenly great. It seams as a pope himself, he was very outspoken in his work. He had an open heart and mind in showing his hope-filled spirituality. Pope John cared for the people and their lives.
During World War II, he helped save lives of many Jewish families.
He had a big part in renewing and modernizing the Catholic Church. He was not only part of the church, but the whole world. He was a very gracious and warm hearted man. He worked for and with the people.
He spread wisdom all through out the world. For that reason, he left a long lasting legacy.
To me, wisdom changes many lives. For that reason, I believe Pope John changed many lives. Not only mentally, but spiritually.
