Cheapest most effective method of sound insulation?
Where I live we’ve the enjoyment (spot of sarcasm in here) of the morning rush hour traffic. The kitchen window of the apartment looks on the main road.
Whats the cheapests best way to insulate against road noise?
(double glazing isn’t an option; exterior shutters aren’t an option either) – it’s got to be something retro fitted inside, which we’d close up at night to enjoy a peaceful nights sleep. I’ve seen cork board used somewhere…? or even sound insulating curtains…
A microphone is used to pick up the sound that is then analyzed by a computer; then, sound waves with opposite polarity (180° phase at all frequencies) are output through a speaker, causing destructive interference and cancelling much of the noise.
Residential soundproofing aims to decrease or eliminate the effects of exterior noise. The main focus of residential soundproofing in existing structures is the windows. Curtains can be used to damp sound either through use of heavy materials or through the use of air chambers known as honeycombs. Single-, double- and triple-honeycomb designs achieve relatively greater degrees of sound damping. The primary sound proofing limit of curtains is the lack of a seal at the edge of the curtain. Double-pane windows achieve somewhat greater sound damping than single pane windows. The increase in soundproofing with higher energy efficiency windows is primarily due to the better seals on double-pane than single pane windows. Significant noise reduction can be achieved by installing a second interior window. In this case the exterior window remains in place while a slider or hung window is installed within the same wall opening.
Since the early 1970s it has become common practice in the United States (followed later by many other industrialized countries) to engineer noise barriers along major highways to protect adjacent residents from intruding roadway noise. The technology exists to predict accurately the optimum geometry for the noise barrier design. Noise barriers may be constructed of wood, masonry, earth or a combination thereof. One of the earliest noise barrier designs was in Arlington, Virginia adjacent to Interstate 66, stemming from interests expressed by the Arlington Coalition on Transportation. Possibly the earliest scientifically designed and published noise barrier construction was in Los Altos, California in 1970.
I’d go with both, cork board is cheap and easy to cut to size, you can put ‘em up and take ‘em down as you please, curtains are great, you can just push ‘em aside when not in use. neither is very expensive nor hard to put up

Use
in building suspended ceiling somehow that ceiling join neighbour room and
partition is mounted up to suspended
ceiling may significant decrease room to
room sound insulation. In this paper are presented test method of estimation
room to room sound insulation for suspended ceilings. Measurement stand using
to estimation this acoustical parameter are characterised on example Department
of Acoustics of Building Research Institute. Principles of estimating influence
of suspended ceilings on acoustical insulation between rooms are discussed. It
is taken into account both formulas given in PN – EN 12354 – 1:2002 and methods
of estimating elaborated by Building Research Institute. It is given examples
of calculating and results of measurements carried out in building.
