With the help of these headphones, you can eliminate all the unwanted noise and sound. Does it sound weird about how can headphones create silence? It may, but that is the technology.

How Does It Work?

It works due to the noise cancelling technology which works brilliantly. This technology is controlled by analogue circuits or even by digital signal processing. This technology is created by some algorithms that are designed in such a way that it can analyse the waveform of the background noise. Then a signal is generated based on the particular algorithm that will either reverse the original signal or shift it. This signal which is reversed is amplified and another sound is created by the transducer.

This sound wave created is directly proportional to the amplified version of original sound wave. It can create a destructive interference which can effectively reduce the noise volume. So, this is the technology that works in the active noise cancelling headphones. The sound you perceive through these headphones is reduced in volume with the help of noise reducing or cancellation technology. These headphones are different from that of the normal headphones that you use for listening to music.

In the Early Years: Technology improved for Oneonta police in 1935

Criminals in 1935 would not find Oneonta to be a “pushover” town when it came to law enforcement.

“The Oneonta Police department is preparing to meet the modern gangster on even ground,” The Oneonta Star reported on Monday, Jan. 21, that year. “In the near future, Chief Frank N. Horton announced yesterday, the department will be equipped with a sub-machine gun and a two-way radio-telephone service.”

 These were state-of-the-art technology upgrades for the time and Oneonta appeared to be proud of them, approved by Common Council in the 1935 budget and said to “bring Oneonta’s Police department on a par with other cities in the state, and will materially aid in preventing crime.”


Officers were ready to be trained to use the machine gun, which could fire a 50-shot drum in three seconds, a rate of 800 shots per minute. It weighed nine pounds loaded, so the weapon could be used with one hand like an ordinary revolver for single-shot fire.

To the best of my knowledge, there was never a time or crime in that era that required such firepower in Oneonta. The other new crime fighting tool, the two-way radio, was handy and useful.

By April, the radio equipment had arrived and been installed at police headquarters (then found at the Oneonta Municipal Building, today’s 242 Main St.), as well as the two “prowl” cars used on the streets. Tests were made all over the city and outside the limits, and all transmissions were strong and clear.

Prior to this new technology, The Star reported that officers had to watch for a red light at the top of the municipal building, indicating an emergency was in progress. Instead of awaiting the arrival of a prowl car to pick up the emergency information at headquarters and go, officers could now be dispatched and head to the scene immediately.

Another advance in police work in Oneonta came in March 1935. The department sought supplies used for fingerprinting individuals who wanted to have their fingerprints on file for personal identification purposes.

“Several months ago the department of Justice advocated national fingerprinting,” said M.L. Thomas, a fingerprint expert in the department. “Many Oneontans responded and their records are now on file at Washington, D.C.” It appears the program was tried earlier and was now becoming a permanent part of Oneonta’s police work.

Outreach to young people was part of crime prevention in 1935, just as it is today. On Thursday, Feb. 14, Police Attorney Joseph P. Molinari was a guest speaker at Oneonta High School.

“Crime does not pay and the life of a gangster is short,” Molinari told the students, himself a 1919 graduate of OHS. He pointed out the short careers of John Dillinger, “Pretty Boy” Floyd and “Baby Face” Nelson, stating that “these criminals could never have enjoyed life on their ill-gotten gains, as their luck could not go on forever. In the end they were killed and society was avenged.”

Molinari was in his early career at the time in Oneonta. It was only about a month later, Thursday, March 7, when Molinari announced he was seeking the post of Otsego County district attorney, a job he was elected to. In 1943, Molinari became Otsego County judge, and in 1951 New York’s Sixth Judicial District Supreme Court justice.

While police work was becoming more high-tech in 1935, the routine tasks still needed to be done, which many area residents of 2015 might identify with.

“Stop does not mean slow,” Chief Horton declared on March 25 while announcing that motorists must observe the various stop signs about the city. Police opened a campaign that day to compel motorists to observe the signs and had issued four summonses to drivers failing to stop. Those drivers were set to appear before Judge Frank C. Huntington in city court.

Interestingly, the signs were triangular in shape and made of iron, but the article in The Star didn’t tell what the color was at the time.

On Monday: The region went in front of the cameras for production of “Susquehanna Stories.”

Mark Simonson is Historian of Oneonta City, Twice a week he writes for the thedailystar.com, including this article. What he outlines in this article is more about Two way radios, but also early 20th century crime prevention techniques.

College Quarterbacks' Earpieces

Quarter backs plays an important role in American football. They are charged with the role of moving the team forward and ensuring that the play is perfect and that every move is coordinated towards the rival side in order to win. They act as leaders of the offensive team and are responsible for calling the play in the huddle. Do college quarter backs wear earpieces? That is always a million dollar question to every fan.

Due to their important role, defensive backs are allowed to wear earpieces in order to receive instructions from the coach as well as get the best tactics on how to make the best moves and ensure that they are able to push the rival team. Instructions come from the coaches since they are at a vantage point to clearly observe the other team and notice the flops of their team as they look forward to counter the other team and pursue them to make the best drills through the defensive backs.

Quartet backs are well familiar with their role and for this case the wearing of earpieces is very important in the game and tackles. It provides them with the idea of what to do next and avoid making similar mistakes since a quarterback acts as the team's driver. A quarterback will play well, with his confidence boosted and therefore the team performance will definitely be improved as much different calls for the play are made. It is a perfect mechanism employed to lure the other team and ensure that victory is directed to the team with a great quarter back. Do college quarterbacks wear earpieces? The answer is yes, the coach always has a hard task while selecting a quarter back since his role is great and it demands somebody with the ability to multitask, this to play, listen and lead the entire team to the decisions that he has been instructed without necessarily having to fail.

Earphones are perfectly designed and well fit in their helmet so that the quarter back can receive instructions clearly. They are well made to ensure that there is clear communication when it comes to getting the instructions as the game progresses. Much of the information relayed is the offensive play in and it serves an important fundamental role in ensuring that communication is paramount to the outcome of the game, for example, getting instructions like triple actions means that the quarterback will only pass the ball a few times in the game.



The earpiece does not run on throughout the game, it is designed to be automatically switched off at W15 seconds left on the play clock, a dedicated official in the college American Football is charged with this role to ensure that all is well. Once switched off, the radio is not turned on until the end of the game. Due to this unique advantage to the quarter back, he is allowed to have a designated W/a green dot placed on the back of the helmet. He is unique and plays such an important role in the game thus having to acquire this different stature.

Microsoft Co-Founder Discovers Last Resting Place Of Legendary Japanese Warship

More than 70 years after American forces sank it, the legendary Japanese battleship Musashi has been discovered resting on the seafloor at a depth of 3,280 feet (1KM) below the water’s surface.

The expedition, headed up by Microsoft co-founder Paul Allen, discovered the wreck of the Musashi off the coast of The Philippines.



Allen’s private yacht, the 414-foot-long (125 meters) M/Y Octopus located the wreck in the Sibuyan Sea earlier this month, but the team has declined to offer details regarding the ship’s exact location.

Mr. Allen is known to have been fascinated by the riddle of the lost battleship and has been searching for its final resting place for 8 years.

The Mushashi met its end during the Battle of Leyte Gulf in 1944, and it is thought that over a thousand men, almost half of the ships 2,399-strong crew compliment was killed during the sinking.

The Musashi is a well-known battleship of the era because it was considered to be one of the largest â€"and most technologically advanced- warships ever built at the time. The Musashi was 862 feet long and weighed in the region of 66,225 metric tonnes. However, despite her immense size and reliable eyewitness accounts of her sinking, the precise location of the wreck remained unknown for over 7 decades.

The Musashi’s sister ship, The Yamato, met its end in 1945. The wreck was lost until the 1980’s, when shipwreck hunters discovered her remains 180 miles southwest of Kyushu. The ship was split in two and was found at a depth of 1,120 feet (340 m).

Some underwater footage of the Musashi has been released to the public already. The footage reveals the catapult system once used to launch planes, a 15-ton anchor and the turret from a naval gun.

The ship took her name from the famous Japanese samurai, philosopher and artist Miyamoto Musashi. Musashi was known for his psychological approach to duelling, as well as his unorthodox fighting style. His ‘Book of Five Rings’ (Go Rin No Sho) is considered a classic text on the subject of conflicts and personal discipline.



Musashi made his first kill at just 13 and won his most famous bout by killing the renowned samurai Sasaki Kojiro on the island of Funajima (using a modified oar that he had taken from the boat that carried him to the island). He is the founder of the Niten Ichi-ryu (‘the school of the strategy of two heavens as one’ â€" loose translation) School of swordsmanship. Musashi partook in around sixty duels, many of then to the death. He retired undefeated and died in 1645, probably from cancer.

Returning to the present, a statement on Paul Allen’s website says that, by discovering the legendary battleship, his team hopes to “bring closure to the families of those lost”.

Mr. Allen has further pledged that he and his team plan to work closely with the Japanese government in order to ensure that the wreck of The Musashi is treated "respectfully and in accordance with Japanese traditions."

The headset also charges up fairly quickly and does come with a wall charger, but not much else. The one thing with the chargers on this one is that not many devices use the same connector. The noise cancellation is great when walking down a busy street or when driving.
