Please answer the following question: Information:  - Common law (also known as case law or precedent) is law developed by judges, courts, and similar tribunals, stated in decisions that nominally decide individual cases but that in addition have precedential effect on future cases. Common law is a third branch of law, in contrast to and on equal footing with statutes which are adopted through the legislative process, and regulations which are promulgated by the executive branch. In cases where the parties disagree on what the law is, a common law court looks to past precedential decisions of relevant courts. If a similar dispute has been resolved in the past, the court is usually bound to follow the reasoning used in the prior decision (a principle known as "stare decisis"). If, however, the court finds that the current dispute is fundamentally distinct from all previous cases (called a "matter of first impression"), judges have the authority and duty to resolve the issue (one party or the other has to win, and on disagreements of law, judges make that decision). Resolution of the issue in one case becomes precedent that binds future courts. "Stare decisis", the principle that cases should be decided according to consistent principled rules so that similar facts will yield similar results, lies at the heart of all common law systems.  - Gardiner Greene Hubbard (August 25, 1822  December 11, 1897) was an American lawyer, financier, and philanthropist.  - Massachusetts ; officially the Commonwealth of Massachusetts, is the most populous state in the New England region of the northeastern United States. It is bordered by the Atlantic Ocean to the east, the states of Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state is named for the Massachusett tribe, which once inhabited the area. The capital of Massachusetts and the most populous city in New England is Boston. Over 80% of Massachusetts' population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry. Originally dependent on agriculture, fishing and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the 20th century, Massachusetts' economy shifted from manufacturing to services. Modern Massachusetts is a global leader in biotechnology, engineering, higher education, finance, and maritime trade.  - In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the "reception" of such waves and their "perception" by the brain. Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz. Sound above 20 kHz is ultrasound and below 20 Hz is infrasound. Other animals have different hearing ranges.  - The Bell Telephone Company, a common law joint stock company, was organized in Boston, Massachusetts on July 9, 1877, by Alexander Graham Bell's father-in-law Gardiner Greene Hubbard, who also helped organize a sister company  the New England Telephone and Telegraph Company. The Bell Telephone Company was started on the basis of holding "potentially valuable patents", principally Bell's master telephone patent #174465.  - Daniel Drawbaugh ( July 14 , 1827 -- November 2 , 1911 ) was a purported inventor of the telephone for which he sought a patent in 1880 . His claims were contested by the Bell Telephone Company , which won a court decision in 1888 . Described as a bearded rustic tinkerer from Yellow Breeches Creek , Pennsylvania , he claimed to have invented a telephone using a teacup as a transmitter as early as 1867 , but had been too poor to patent it then . In a lower court his case was well - financed by the People 's Telephone Co. and brilliantly argued in court by Lysander Hill . But he `` blew it '' by drawling in court `` I do n't remember how I came to it . I had been experimenting in that direction . I do n't remember of getting at it by accident either . I do n't remember of anyone talking to me of it . '' The lower court findings were confirmed by the Supreme Court in 1888 , as noted in The Telephone Cases . Drawbaugh was born on July 14 , 1827 , in Cumberland County 's Eberley 's Mills which is just outside Harrisburg , Pennsylvania . According to his obituary printed in the New York Times on November 4 , 1911 , he invented many appliances , for example : pneumatic tools , hydraulic rams , folding lunch boxes , coin separators and even is said to have invented a wireless phone that could be used 4 miles away . He died November 2 , 1911 in his laboratory while working on a wireless burglar alarm . Many of his surviving York County relatives attended a ceremony to dedicate a historical marker located at the site of the inventor 's workshop and home in 1965 .  - The human voice consists of sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming, etc. The human voice frequency is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. (Other sound production mechanisms produced from the same general area of the body involve the production of unvoiced consonants, clicks, whistling and whispering.) Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx, and the articulators. The lung (the pump) must produce adequate airflow and air pressure to vibrate vocal folds (this air pressure is the fuel of the voice). The vocal folds (vocal cords) are a vibrating valve that chops up the airflow from the lungs into audible pulses that form the laryngeal sound source. The muscles of the larynx adjust the length and tension of the vocal folds to fine-tune pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue, palate, cheek, lips, etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to strengthen it or weaken it as a sound source.  - A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user.  - Alexander Graham Bell (March 3, 1847  August 2, 1922) was a Scottish-born scientist, inventor, engineer and innovator who is credited with patenting the first practical telephone.
