audioguru Posted July 6, 2006 Report Share Posted July 6, 2006 can u help me to add innovations in the room noise detector?Are you talking about our project?http://www.electronics-lab.com/projects/sensors/012/index.htmlIt detects and indicates when sounds exceed a certain loudness.You could add a lowpass filter so it detects only low frequency sounds, add a bandpass filter so it detects only mid-frequency sounds and add a highpass filter so it detects only high frequency sounds.You could replace the output transistor with an LM3915 bar-graph driver IC that drives 10 LEDs and shows actual loudness.
