Acoostic switch

Cilj ovog rada je izraditi akustičnu sklopku tj. sklop koji reagira na zvukove i šumove iz okoline, te ukapča i iskapča strujni krug. Akustična sklopka registrira zvukove i šumove iz okoline preko mikrofona koji pretvara zvuk u električni signal. Nakon registriranog zvuka aktivira se relej koji napaja svjetleću LED diodu koja je indikator da je sklop pod naponom. Nakon sljedećeg registriranog zvuka, sklopka će se isključiti. Brod je specifična okolina koja ima svoje zahtjeve i pravila. S napretkom tehnologije, na brodovima se povećava stupanj automatizacije. Akustična sklopka ima široku primjenu u praksi. Primjerice, na brodovima bi se mogla koristiti kod zaštite uređaja osjetljivih na buku. Također, mogla bi se koristiti kod regulacije svjetla u svrhu optimiziranja potrošnje električne energije.Objectiv of this assignment is to make an acoustic switch. An acoustic switch is a device that reacts on sounds and noises from the environment. The device works by switching the circuit on and off. The acoustic switch registers sounds and noises through a microphone that converts sound into an electrical signal. After the sound is registered, a relay is activated and it supplies the light-emitting diode which is an indicator that the circuit is energized. After the next registered sound, the switch will turn off. Ship is a specific surrounding that has requirements and rules. With the advancement of technology, the degree of automation on ships is increasing. The acoustic switch has a wide application in practice. For example it could be used to protect noise-sensitive devices. It could also be used in light regulation for the purpose of optimizing electricity consumption
