Observation Project - accommodative "Noise" Reduction
Because noise arises through the din of simultaneous conversation....
The idea for this project occurred to me after having been in places where groups of people, that happen to fluctuate in size at any given time were going about their business as they might do at these locations. A mall, a reception area where a function can be held or a vestibule of a building where people might congregate prior to an event in an adjoining space. The common and expected thing that arises from each of these places is - noise. I generally don't care to have to yell to the person next to me to have a conversation or provide some necessary information, but that often is the case in spaces where people are. The noise level will not always be the same all the time at these places and so, the need to attenuate the noise will vary. The goal is to assist in providing an aural environment where noise can exist as it needs to but not so that it becomes a force to be reckoned with for the sake of any individuals need to be understood or who simply would like to hear themselves think !
The architectural consideration of a given space cannot be ignored so, the system must not only be consistent with design needs but also accommodate the users. It should interact on a realtime basis with the need of the people in the environment, adjusting, for the time necessary.
This system provides for an adjustable mechanism to increase as needed, the acoustic absorptive capability, essentially, of the space. The reduction of competing background noise, helps to maintain a more comfortable overall sound level. More normalized volume levels for conversation are then realized by the occupants. The need to shout over each other is diminished, civility is increased, energy is conserved and more is right with the world.
This is a sketch of a noise reduction unit. It could be mounted on a surface or installed flush in a wall, between wall studs, approx 14-24 " wide. The housing and legnth of prowing absorptive panel could be sized to fit this range.
Sensors to count the number of persons within a space, for reading decibel levels and for frequencies or frequency ranges ( for standing wave problems) would relay threshold information ( perhaps wirelessly) to programmed PIC chip(s) for an individual unit or for an array of units depending upon readings relayed from multiple points. A flow of calculations for the reveal of absorptive materials would be made in regard to the known coefficients of persons within and materials confining the space in question. Based on these calculations the units would be engaged to reveal more or less absorptive material by having the front of the unit prow outward by use of servo motors allowing a covering panel to slide open, revealing various densities of acoustically absorptive materials. Facing of the panels could be of fabric(s) consistent with room decor covering any appearence of mechanism
