How can I create a device that indicates the direction of sound source?

AI Thread Summary
To create a device that indicates the direction of a sound source, consider using the principle of sound localization, similar to how human ears perceive sound. The device could utilize microphones placed at a distance apart to detect sound waves, measuring the time delay between when the sound reaches each microphone. Implementing a microcontroller can help process the signals and determine the direction based on the time differences. Additionally, incorporating visual indicators, like LEDs, could enhance the user experience by showing the direction of the sound source. This project combines elements of acoustics, electronics, and programming for an engaging science exhibition.

hi Guys,
there is a science exh. in our school, i am thinking of creating a device which indicates the direction of sound source , is there any way to make it ?

Use your ear as an example. You can tell the direction of sound based on the time delay the sound takes to get from one ear to other.

You would need to design something along these lines. Any ideas where to start?
 

Thread 'Is calling fictitious forces not real just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
