Sound or popularly known to us as noise is one of the widely available energy sources which have its range extending al-most to infinity. The noise is considered to be a great contribu-tor in the increasing pollution which is studied under the cat-egory of noise pollution.
Let us first understand the basic definition of sound. Sound basically is mechanical wave that is an oscillation of pressure transmitted through some medium (like air or water), com-posed of frequencies which are within the range of hearing. Thus, considering sound as the wave we can imagine it as the flow of energy from one point to another with the help of a medium as air. The sound waves can be longitudinal as well as transverse as per direction of vibration of the sound parti-cles called phonons.
Sound that is perceptible by humans has frequencies from about 20 Hz to 20,000 Hz. In air at standard temperature and pressure, the corresponding wavelengths of sound waves range from 17 m to 17 mm.
this ppt discuss about how sound energy get converted into electrical energy using piezo electric material. In the bottom slides i gave just figures which are self explanatory.

After a successful Ruby Meetup in June, Amura hosted PunesRuby's Meetup for the month of November '15. We had our very own team members give some really awesome talks about Ruby and technology in general.
RequireJS - An Introduction - Vrushali Waykole
WebSockets in Rails - Vineet Ahirkar
Information about Ruby Association Grant - Sameer Deshmukh
I delivered this presentation in Dublin Web Summit in November 2014.
The session aimed at helping startups to decide what and how to track. I covered why metrics matter and what every startup should measure at different stages of their lifecycle. The session also covered Analytics mistakes that startups must avoid and some Analytics best practices.

When exposed to ultraviolet light, the GFP absorbs photons and emits electrons, which travel around a circuit to produce electricity."
