Request: Sound canceller / radio frequency canceller. Here's the sound canceller, which is prices at around $30,000 Euros, and powers itself. (using radio frequency) http://www.digitaltrends.com/wp-content/uploads/2013/10/sono-technical-setup.jpeg Aditional request: Radio Frequency canceller. Ideally it would be something similar in concept, but would be able to cancel specific ranges also. Thanks.

Hello all:) I was wondering if I could get some help and advice about a project I've had in mind for a while. The idea is to use a modified electronic megaphone to produce sound that's antiphasic of the microphone input. I want to keep the execution as simple as possible to retain signal quality and keep it something I might be able to do myself with a little studying up. I got the idea when I noticed if you incorrectly wire a couple speakers one can produce output that's 180 degrees out of phase, cancelling most of the sound emitted. Ultimately I'd like to use the device to help quiet the sounds of the power tools I use as a favor to my neighbors and to save my hearing a bit:) This should be doable since I could keep the megaphone near the source. Thanks a bunch for any help, Pete

I just joined last night, but when I finally printed out the instructions for the bench, they were much less detailed than I need/expect. I need to cancel this membership immediately and get a refund. Thank you. Virgil Klunder email@example.com

I upgraded to a pro membership on September 14th and got the receipt in my e-mail for $8.85 for a three-month Pro subscription. On September 25th I got an e-mail saying: Hi daemonsan, We just wanted to let you know that your Pro membership has expired. Your Instructables membership is now back to the regular level. If you would like to keep your Pro features active, you can upgrade to Pro at any time here: and when I come to the website I am indeed a normal user again. What can be done to fix this?

Many brands compete with noise-cancelling technology, but all offerings seem tuned to mitigate frequencies other than voices. I appreciate that on an airplane or gun range, but in an open office plan, the only common attempt at mitigating vocal pollution is to add white noise variants. White noise systems have limited effectiveness and alleged health drawbacks. My noise cancelling headphones cut the white noise, effectively enhancing voices that I want to shut out. I can use "sound-isolation" instead of "noise-cancellation" but they are bulky and hot. I'd think it would be possible to use noise-cancellation technology to target vocal frequencies. Thoughts?

Example: when you save a certain file on your computer and if you close it.the file you save will be gone..
The Grateful Dead's wall of sound prevented feed back by having two mics for each vocalist with one of the mics 180° out of phase of the other. Then mixing both mics on the same channel. So the only information that wasn't canceled was the voice. This gave me an idea. I took a handset and added a mic facing backward from the existing mic. Then wired the second mic out of phase. Apparently there's more to it electrically then just wiring the other mic backwards because the handset went dead. Is this possible with just parts salvaged from old phone equipment?

I'm looking for advice. (now this is difficult to explain but I'll try my best) I am trying to design a way to have a dance floor in an open area that will have an area where you can hear the music but away from the area it can't be heard. I'm attempting to do this using an array of speakers around the dance floor that will cancel out the music past the dance floor. Each speaker will face away from the area and be equipped with a microphone (directed torwards the main speaker) that then goes through and amplifier and then to the speaker (wired up so that it will emmit an opposing sound wave). This would essentially create a sound barier. I have attatched a picture as a visual aid.

I couldn't find my membership and thought that it expired so I started a new one. But today I found my old one and now I am paying for two! My user names are fernmama and fern mama. Fernmama is paying installments and fern mama paid for two years. Can I please cancel Fernmama's membership?

I am playing with an idea. Higher end cars come with active noise cancellation systems to make the drive quieter and more enjoyable. However compact and subcompact class cars do not. With the noise canceling technology is available on every shelf for headphones, I am wondering if this could be hacked and repurposed to reduce road noise in a car. The system (Im presuming) would require one microphone, one noise canceling circuit board, and one speaker per wheel well. So it would require two pair of noise canceling headphones to accomplish. The idea is to improve the cabin noise quality in an off the shelf kind of way. Currently there are no aftermarket systems within the normal financial reach of most people. Only a hand full of aftermarket systems out there are available and priced @ 4K USD or more. If this works, it could be marketed at around 100 USD per unit. And provide a much nicer driving experience to the compact and subcompact cars. By placing the microphones under the carpet and on the wheel wells metal surface the system should ignore the stereo, and correct road noise transmitted from the wheels to reduce cabin noise. Stereo interference is a common problem with cabin mounted microphones on OEM systems. So, your mission if you choose to accept it, is to devise a way to reduce road noise in a compact or subcompact car using off the shelf noise cancellation circuitry available to the average person. If your successful this should be a very easy way to upgrade most cars not equipped with such a system. Having a noise canceling system in a car reduces noise fatigue, and improves the driving experience for all of us.

I'm making a mixture thats basically sugar and corn syrup, what can I add to the mixture to stop it from being so sweet that it tastes bad? I'm looking for something like a flavor or juice of some kind, and was wondering if lemon juice or something common like that would cancel it out well. As in it works with small amounts compared to large amounts of sugar. And it also has to not affect gelatin. Thanks.

I accidentally broke by Sony MDR-NC7 headphone's cable, and when I tried to repair it I discovered that it had four cables instead of the usual three. Does it have anything to do with the fact that they're noise-canceling headphones? Two of the cables are golden, one blue and the last one red.

I have a pool pump. it seems a bit loud especially to the neighbors. I tried to buy some foam and 'for sale' signs, glued them together and wrapped them around the pump but it's still too loud, and I'm worried about overheating the pump/motor because of the wrapping of the motor/pump. Is there some way to build a sound cancellation system for this for say a hundred bucks that will run outside?
Question by kishjeff | last reply
I know that noise cancelling headphones exit but is it possible to scale that up and have the out-of-phase noise played through speakers? If so, and the microphones were against the wall of the offending neighbour and the speakers were to be aimed at that wall, would the noise be noticeably reduced? Thank you.
