Abstract
Abstract of new invention for household Active Noise Cancelling speaker system.
Abstract- A new device that will circumvent multiple social problems related to unwanted noise aggression.
1- People living in urban areas are often prone to live in vicinity of noisy environment. City traffic, outside noise coming from trucks, cars, can certainly degrade people quality of life. This device would greatly reduce or totally eliminate these outside noises.
2- Snoring is widespread and is detrimental to many people. This device eliminates the sound of snoring and permits spouses to have a better sleep.
Description ¨This device is fitted with an electronic circuit that actively cancel sound waves. It receives the incoming sound and emits an opposite sound, rendering the incoming sound inaudible to a listener.
Sound is a pressure wave, which consists of alternating periods of compression and rarefaction.
A noise-cancellation speaker system emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out ¨ an effect which is called destructive interference.
Modern active noise control is generally achieved through the use of digital circuitry. Adaptive algorithms are designed to analyze the waveform of the background aural or non-aural noise, then based on the specific algorithm generate a signal that will either phase shift or invert the polarity of the original signal. This inverted signal (in antiphase) is then amplified and a transducer creates a sound wave directly proportional to the amplitude of the original waveform, creating destructive interference. This effectively reduces the volume of the perceivable noise to a person hearing.
A noise-cancellation speaker may be co-located with the sound source to be attenuated. In this case it must have the same audio power level as the source of the unwanted sound to effectively cancel. Alternatively, the transducer emitting the cancellation signal may be located at the location where sound attenuation is wanted (e.g. the user's ear). This requires a much lower power level for cancellation but is effective only for a single user and only in close proximity. Noise cancellation at other wider locations is more difficult as the three-dimensional wave fronts of the unwanted sound and the cancellation signal could match and create alternating zones of constructive and destructive interference, reducing noise in some spots while doubling noise in others. In smaller enclosed spaces (e.g. a bedroom) global noise reduction can be achieved via multiple speakers and feedback microphones, and measurement of the modal responses of the enclosure.

Problem solving ¨
One area that is problematic is the living spaces that could be located in a noisy environment, where low frequency noises are present. In order to improve the quality of living in such environment, a properly sized active noise cancelling speaker system would eliminate the unwanted noises but retain high frequency sounds as fire alarms, alarm clock, baby communicator, door bells, telephone, all these sounds that are necessary for the safety of the whole family.
Another problem to solve is the quality of sleep for spouses that must endure snoring sounds every day, and suffer from sleep deprivation, tiredness, irritability that leads to certain but not limited to social and interpersonal issues.
A 2001 study at the Chicago Medical Institute suggested that sleep deprivation may be linked to serious diseases, such as heart disease and mental illness including psychosis and bipolar disorder. The link between sleep deprivation and psychosis was further documented in 2007 through a study at Harvard Medical School and the University of California at Berkeley. The study revealed, using MRI scans, that sleep deprivation causes the brain to become incapable of putting an emotional event into the proper perspective and incapable of making a controlled, suitable response to the event.
The negative effects of sleep deprivation on alertness and cognitive performance suggest decreases in brain activity and function, primarily in the thalamus, a structure involved in alertness and attention, and in the prefrontal cortex, a region sub-serving alertness, attention, and higher-order cognitive processes, rendering affected people prone to accident.
