sound over smell

Could a certain sound frequency cancel out smell? as in the sound waves dissolve the smell molecule? i need to do a lot more research on this... but if it actually heads in the direction of a product where a non-hearable sound kills all the smells i copyright the idea as of now if you steal my idea and make money i will kidnap you and shred all the money you make until it is liquid and inject it into your bloodstream.

Doorbell - press button and make an explosion sound

I'm thinking of making a prank doorbell where you press the button and an explosion sound goes off. I seem to be a little stuck on choosing a simple audio input that I can put an explosion sound on. Any suggestions? thanks!

Sound Activated LED's

Good Afternoon everyone, A friend of mine asked me to help him build something and I sort of hit a snag in the process. I know how to make LED's flash to the beat of music but what he wants is so that way when there are sounds around him the LED lights flash with the sounds around him (Such as if he was at a party, the LED lights would flash with the beat of the music even though they weren't connected to it.) Is this possible and if so what would I need to build or get? Thank you! Sincerely, Khris

help on sound controlled light

Hello! I am developing an art project in which I will need to control one lightbulb's intensity by the sound coming from one microphone. I haven't got the knowledge to build the circuit and the arduino program. I believe this is not a very hard thing to make. I just need to control a bigger voltage with a smaller one right? i would really appreciate some help...

Recording ultrasonic sound

I looked up at bat detector, a device that converts ultrasonic signals into audible sounds. Most bats produce high frequency calls which are often higher than a human ear can pick up. A bat detector picks up the frequencies and then converts the sound into a lower, audible frequency. I was thinking if I could get a bat detector, I use it to capture the ultrasonic sounds.While bat detector could pick up these high frequencies, it would be interesting to see how it will pick up the faintly heard, to human ears - sounds of the industrialised areas/city or even at isolated/quiet areas. The bat detector I want to use is this - ... _Bat4.html I'm thinking of hooking up the bat detector to a digital recorder and a binaural microphone and capture the sound through those equipments. I would greatly appreciate your suggestions/opinions on this matter.

I messed up one sound setting in Vista. And now I can't hear youtube videos...

Can you help me? Trying to tweak the sound, on my laptop running vista, I changed the setting under speakers properties>advanced>Default format. I foolishly changed the default format to another setting, thinking I could always switch it back. Immediately the sound from my youtube windows ceased. I tried switching it back and applying the settings. No joy. I tried restoring default settings. No joy. I can still hear windows sounds, just not stuff I WANT to hear. Anybody know how I can fix this? EDIT: Nevermind, I fixed it...errgh...should've just rebooted in the first place.

gentle touch activated sound?

I have a little toy that makes noise when you squeeze it that I want to give as a Christmas present, but tiny little hands have trouble doing the squeezing properly, so I want to do a little surgery on it so that the sound activates with just a gentle touch instead.  Such as if you flick it, pet it, pick it up... that sort of thing.  I know when I was little, we had a doll that was supposed to make noises when played with, but it was so sensitive that it would go off from just the blow of our AC.  My problem is, I've no idea what parts I need to do this.  Can anybody help point me in the right direction?  And I only have about a three inches to work in, so it needs to be fairly small. Thanks.

Sound activated switch

Hey, my friend is a drummer and he's trying to install LEDs inside each one of his toms that would come on when he hits the tom. He doesn't know anything about electronics so he asked me and I don't know much either so I'm asking all you awesome people at Instructables. What I want is a simple sircuit that will not cost me above £5 that will allow me to do what I mentioned above. I have a soldering iron and can solder stuff easily so I just need the parts and (preferably a stripboard) layout. He will be using a max of 16 red 2v 20mA LEDs in each tom so the circuit will have to be able to supply either approx. 32v 20mA if in series, or 2v 320mA if in pararell. So, any recommendations?

Soundproof Theater

After playing Super Smash Brothers Brawl at a party in a sound proof room on a projection screen, I've been trying to convince my parents to do the same to one of our unused rooms. Build a "teenage hangout". It will be very hard to convince them to do this, the lower the cost, the better. Is there any cheap tricks do doing this (and still look nice)? Memory foam on the walls? Obviously the screen itself will take the most convincing, but if that fails I'll use our 60in TV (three years of begging at it's finest :D ). I might even make it into an Instructable.

Question Re: Installation

I have a few questions regarding a scultpure I am making- To keep it simple, let's say the sculpture is simply a rectangle, ~4'x8'. What I would like to do is set up eight motion sensors (one in each corner and one in the middle of each side) that when triggered activate a corresponding tape player with a tape loop inside to play on a central speaker unit. So the goal is simplest terms is for people to walk around the installation triggering a musical note and with enough people organize a composition or a chord. Each motion sensor would have its own respective tape player, but I don't have the funds to supply eight seperate speakers. I also don't have much money to spend on PIRs, however, ebay has a bunch of PIR home security sensors for around $5. This project is most likely going to be crude, so I'm not overly worried about how sloppy it may turn out. What I imagine is to have the tape players always on, always running their loops, and a way for their respective sensors to allow the sound to play through the speaker. The gaps I need filled- 1) Is it sensible to use the PIR sensors I'm finding on ebay? (Aleph XP-40, Ademco 998) 2)short of buying eight speakers, is there a way to hook up all eight tape players to a central speaker unit? 3) If I am making this overly complicated, might you know of a better way to accomplish the task?

Mosquito sound that adults cant hear

I was at school the other day and I heard this annoying ringing sound. so I was looking around wondering what the hell it was when the teacher(who's probably 40 or 50)was like "what are you doing?" I said that I hear a ringing sound. then he said that I was crazy and there wasn't anything ringing. then the other classmates started listing and they all heard it also. I talked to that kid after class and was like where did you get that sound, and he replied its a ringtone. so when I got home I looked into it more and found out that people who are older supposevely cannot hear it so I played it for my mom and I was expecting her to hear nothing and then she was like "turn that annoying sound off right now". I was like did you hear it. everybody says she has super human hearing. here is the link to test it out.

Sound Locator Circuit?

Hey all, Here's an idea maybe one of you solder-jockeys can help me out with: Ever have a sound that you'd like to find the source of, but your ears can't tell you where it's coming from?  I'd like to build a circuit to do that. I was thinking of something like three electret microphones with op-amps between them in differential mode.  That would give three signals that would be, presumably, the ratio of sound coming from each mic.  (And, therefore, an indication of direction.) Of course, I'd also like to get an adjustable bandpass filter in there somewhere to isolate just the sound I'm looking for.  That's the part that complicates all designs I've thought of. And then, if I could somehow figure out distance too, that would be the ULTIMATE! Here's one possible use case: A car makes a funny squeal noise a highway speeds. The mechanic takes out this device and magnets it inside the hood.  He runs a control wire back to the cabin. Once the car is in motion and making the desire noise, he adjusts the BP filter using potentiometer(s) and a pair of headphones. The device tells him where (relative to itsself) the sound is coming from. Your bill is less because the problem was diagnosed quickly without a lot of guesswork. Thoughts?

CHALLENGE: Dirty Video Mixer with Sound Sensor!

Hey guys I have a challenge for you all but forewarning I am a bit of a novice with Arduino and electronics in general. I want to adapt Karl Klomp's Dirty & Cheap video mixer (schematic attached) into something a bit more responsive. The original video mixer is essentially just two RCA inputs fed into a potentiometer and then a combined output is produced as a mix of the two original video sources. I want to swap the potentiometer for a sound sensor (image attached) to allow for the mix of the video output to be governed by the volume of the mixer's surroundings. If anyone could please help me that would be great!!! (Even my lecturers are stumped) Thanks in advance guys! Ryan

It would also be quite helpful if you could add a 9-volt battery with a resistor for long life, and possibly put in a more powerful speaker for maximum annoyance.

need some help with my project (boombox)

Hello guys so i have been working on this project for some time (i know its not complicated) and i need some help with it. So i bought this old-school suitcase it was mainly made out of plastic so i glued some plywood  on the inside of the suitcase, ive cut  some holes for the speakers and vuala its semi-completed. So im using 4 mid-range speakers and 1 low-range speakers, so i yesterday i made the first sound test and to say the least the sound quality was terrible (i know it wont be a high quality sound boombox but i have made one some time ago). So my question / request would be if you guys have any suggestions maybe you know some cheap but decent quality amp or know anything about building speakers or stuff like that ( because i have pretty close to none experience in building them) BTW im using lepai lp 838 I would really appreciate any advices or suggestions. THANK YOU! ohh and sorry if this thread is missplaced or if my english is horrible.

Sounds with electronics

So here goes, I am trying to figure out how to make basic sound generating machines. Preferably generating a sound that can be modified with a potentiometer or something of the sort. The principle is simple, these will be for messing around, possibly, if the result is good, using in some random recordings of mine, so most of the machines will have a jack out plug. Anyhow I was wondering, what, in a circuit, actually makes sound, what is the base of all sound generating electronic devices (synth, analog stuff, beepers) what actually creates the wave, the current that is sent to the speakers? Have I just answered my own question by saying current? Is it just the electrical current, and putting random resistors, capacitators, potentiometers and stuff changes the sound that is generated? Any help is more than welcome! and if anything good comes of it, I'll post some sound clips!

Speed of sound question !!

My friend and I were debating : If somebody sitting in the back of a plane cockpit going faster than the speed of sound ( the whole plane that is, imagine it was the SR71 ) insults the pilot at the front will the pilot hear it and turn around to punch the guy sitting in the back? This one might be more understandable: Can someone sitting in the front of a super sonic plane hear the guy in the back, without the help of microphone and all that crap. My friend thinks it is impossible becose the plane is going faster than the speed of sound and the sound from the guy at the back will not go fast enough for it to catch up. I think that is total nonsense Anybody knows the answer ????

Help with Arduino Coding

Hello. I have recently been interested in coding Arduino and the USAF lets me to launchpads to setup remote cameras that are sound activated for a rocket launch. I was working on designing an Arduino connected to one of the cheap sound detector modules on eBay. The camera would be triggered by a short circuit on the digital end, with the sound module on the analog end. The camera is activated by a short circuit on the shutter release, so I though I would have + going into the camera when sound is activated with the other cables on ground. I just needed someone to check over my coding, as I am debating whether or not to buy an Arduino. No errors appeared on the computer, so I don't know if it will work fine or not                                                                                                                                                                                                                void setup() {}   //Just there as placeholder: void loop()    //To repeat a function of detecting sound: {const int SoundDetectorPin = A2;  //Sound Detector Module located at Analog pin 2:   const int CameraTriggerOutput = 3;  //Dual Trigger Output is located at Digital pin 3: //Following is If functions: if (analogRead(SoundDetectorPin) == LOW) //When power is read, if it is LOW, the trigger detected sound:      digitalWrite(CameraTriggerOutput, HIGH); //Pin 3 is given positive voltage: else {  //If opposite happens:     digitalWrite(CameraTriggerOutput, LOW); //When power is read, if it is HIGH, the trigger is detected nothing and no command is excecuted:    } }
