Sound level meter A sound level meter is used for acoustic (sound that travels through air) measurements. It is commonly a hand held instrument with a microphone.The diaphragm of the microphone responds to changes in air pressure caused by sound waves. That is why the instrument is sometimes referred to as a Sound Pressure Level (SPL) Meter. This movement of the diaphragm, i.e. the sound pressure deviation ... How decibel sound level meters work Explain that Stuff How sound level meters work. Sound level meters look quite simple. They have a pointy stick at the top, which is the microphone that samples and measures the sound. The stick keeps the microphone away from the body of the instrument, cutting out reflections, and giving a more accurate measurement. Audio circuits to build ePanorama.net Links Audio circuits to build. The following links to circuit diagrams and building projects I have found from other web sites. I have tested only very few of them so there is no guaratee that those circuit will work as expected.
